Member End Edit window ( Modeling )

Also see :

VIDEO The selection filter is set to ' Member ends '. A member end whose pins are disabled is selected. The Delete key clears all pin information for that end. Auto Pin adds pins to the end. The auto pin information is reviewed and the member that the end is pinned to is raised by changing its " End elevation ." Pins are adjusted and deleted and the member's elevation is changed again, with different results. (Recorded in SDS2 Detailing , v2017.)

-----  Settings -----

User: or .

Member ends that have " User "pins are displayed in the " User " color that is specified at Home > Project Settings > Job > Member Pins .
" User " pins are Auto Pins or system pins. Member pins that have system pins are displayed in the " System " color that is specified at Home > Project Settings > Job > Member Pins .

If this box is checked ( ), the settings on this window are locked and will not be changed during Process and Create Solids or when, for example, a new view is added in the vicinity of this member end or when the framing situation of this member end changes. When you make a change to a pin setting -- for example, enter an offset -- all pins associated with that member end become user pins, and this option is set to " User " after you press " OK " to close this window. You cannot make pins Auto Pins when they are " User ".

If the box is not checked ( ), the pins associated with this member end are system pins, which means that they can change as the member end's framing situation changes or, for example, as new views are added within the member end's vicinity.

If you change this option from " User " to " User " then press " OK ," Process and Create Solids will change the color of the end to the " System " color. Another way to do the same is to select the pin then press the Delete key and press " Yes " on the dialog that opens, then, with the pin still selected, right-click and choose " Auto Pin " on the menu .

Regardless of whether a pin is " User " or " User ", if the item that the member end is pinned to is moved, the member's end will move with the moved item unless other pins constrain such movement.

Disable member pins on this end: or .

" Disable member pins on this end " causes the member end to be displayed in the " Disabled " color that is specified at Home > Project Settings > Job > Member Pins .

If this box is checked ( ), pins that are defined on this window are disabled. This means, for example, that if an item that the member end is pinned to is moved, the member's end will not move with the moved item. You cannot make pins Auto pins when they are set to " Disable member pins on this end ".

If the box is not checked ( ), pins that are defined on this window are fully operational.

Also see: " Default members to disabled restraints " is, by default, turned on at the time a project is started. It causes the ends of newly added members to automatically be switched to a " Disable member pins on this end " and keeps members from being pinned to other entities, thus preventing unselected members from moving when other members are moved or when grid lines are moved. This also helps make it easier for users to apply pins at a time of their own choosing, in a way that controls the outcomes that they want. A " Pin New Member Ends " tool can be used to override the " Default members to disabled restraints " setup choice.

" Add " lets you add a new pin. That pin's settings will be found in a new leaf on this window. There are eight types of pins that can be added. Each pin type pins the member end in a unique way to a member end or grid line (view) or member line .

adds a new pin

1 . Press the " Add " button.

2 . A window opens with the following options. Double-click the option you want, then perform the action that is required of you in the model.

Option Action Required in Model Heading Under Which the New Pin Is Shown
to view Select a grid to pin the member end to.. " View "
to other member line Select a member to pin the member end to. " Other Member "
to other member's end Select another member's end. " Exact Location "
to member's plane No action is required in the model. The new section is created without your having to select anything " Self "
to other member's plane Select a member. " Member Plane "
to other member end's plane Select a member end. " Member End Plane "
spliced members Select a member line. " Spliced Ends "
even spaced members Select a beam that you want the member end to pin to. " Even Spacing "

3 . A new pin ( leaf ) is added on this window. The table in step 2 tells you the name of the leaf. In that leaf, you may be able to adjust settings applied to the new pin.

View

Each view listed on this Member End Edit window represents a distinct view that this member end is pinned to. Additional views can be pinned to by pressing the " Add " button then choosing " to view '. A pin can be deleted by pressing the trash can button ( ) associated with a view leaf .

View: Any grid line/ view in you current model can be pinned to. See grid lines .

The bottom column end that is shown in this example is pinned to three different views, which are named 1.9 and E and AB PLAN . Each pin restrains the column's bottom end to a different plane.

Warning: Be aware that the member end that you are editing will snap to the grid line that you select as the " View " that the end is pinned to. Applying Auto Pins to a member end pins that end only to views that do not cause the member to move; however, manually selecting a view can cause the member to move (after you press " OK ").

For example, if the column's top end is auto pinned to a plan view named Second Floor that is at an elevation of 126-0 and you switch " View " to a different plan view that is at an elevation of 127-0 , your change will result in the column's top end " End elevation " being changed from ' 126-0 ' to ' 127-0 '. " User " will be checked to indicate that the end is no loner auto pinned.

Also see: Member ends that are pinned to a particular view may move as a result of your performing a File > Views/Grids > Move View operation on that view.

Offset: A positive (+) or negative (-) distance (in the primary dimension " Units " or other units ). The " Offset " distance is the distance perpendicular from the work plane of the " View " (selected above) to the member end.

The top column end in this example is pinned to a view named ROOF and an offset of ' -X ' (negative) is entered, causing the column's top work point ( wkpt ) to be a distance of X below the ROOF grid line.

VIDEO A beam's left end is pinned to a view. By editing that beam's left end and increasing the " Offset " to that view, the user changes the beam's left-end " End elevation " and makes that end of the beam move up. (Recorded in SDS2 Detailing , v2017.)

' 0 ' results in the end of the member (its work point) snapping to the work plane of the " View " selected above. For example, if the member is a beam and the " View " is a plan view at 100-0 , then that beam's " End elevation " (for the end being edited on this window) will be ' 100-0 '.

' A positive distance ' moves the end of the member (its work point) away from the direction that the view faces. For example, plan views look downward. if the " View " entered above is a plan view, then entering a positive distance to ' Offset ' and pressing " OK " moves the end of the member upward that distance.

' A negative distance ' moves the end of the member (its work point) in the direction that the view faces. For example, if the " View " is a plan view, then entering a negative " Offset " moves the end of the member downward that distance.

Also see: Member ends that are offset a particular distance from a particular view may move as a result of your performing a File > Views/Grids > Move View operation on that view. The offset will be maintained.

Other Member

A member end can be pinned to an " Other Member ." If the end is pinned to more than one member -- for example, in a vertical brace to beam & column framing situation -- each of these other members will have its own leaf . A pin to an " Other Member " can be deleted by pressing the trash can button ( ) associated with that leaf.

Offset from member line: Manual or Half Nominal Depth .

The member end is pinned to the member line of B_146 . A " Manual X " distance of ' X ' results in the end of the member being moved a distance of X away from the member line of B_146.


' Manual ' lets you set the global ' Manual X ' and ' Manual Y ' and ' Manual Z ' distances that you want the work point associated with this member end to be offset from the member line the end is pinned to. 0 to each of these offsets results in the work point at this member being pinned to the nearest point on the member line. A positive or negative distance moves the work point of the member that distance away from the nearest point on the pinned-to member line.

VIDEO One end of the ridge beam on a hip-and-valley roof is raised, also raising the ends of all beams that are pinned to that ridge beam's member line. The auto pins for each of the beams pinned to the ridge beam have their " Offset from member line " auto set to ' Manual ' with X, Y and Z offsets of ' 0 '. (Recorded in SDS2 Detailing , v2017.)

' Half Nominal Depth ' is the choice made for auto pins on the end of a vertical brace to a beam.

VIDEO Vertical X braces that frame opposite to one another have " Spiced ends " pins. A vertical brace to a beam-column is pinned to the beam with an " Offset from member line " of ' Half nominal depth '. When the beam's left and right " End elevation " are moved up, the X braces remain colinear and the brace to beam-column stays aligned to half the nominal depth of the beam. (Recorded in SDS2 Detailing , v2015.)

Also see: Member ends that are offset a particular distance from a particular member line may move as a result of your performing a Model > Member > Move/Stretch operation on that member line. The offset will be maintained. The same is true if you change the member " End elevation " of one or both ends of that member line.

Exact Location

The Exact Point of one member end can be pinned to the Exact Point of another member end. You can create the pin by pressing the " Add " button then choosing " to other member's end ' then selecting that other member's end. A pin to an " Exact Location " can be deleted by pressing the trash can button ( ) associated with the " Exact Location " leaf .

Lock to elevation: or .

If this box is checked ( ), you can enter a " Level " and/or " Manual X " to constrain the end within a particular plane.

If the box is not checked ( ), the end is constrained along a line through the half-way point between the end points of the two members.

Level: <no level> or a plan view . Any plan view that is stored in your current Job can be selected.

' <no level> ' keeps the ends of the two members in their current position. If a Move/Stretch operation moves one member end from that position, the other end will move as well, unless it is constrained by other pins.

' a plan view ' snaps the end to the reference elevation of the selected plan view. If the reference elevation of that plan view is different than the current location of the member end, the member end will snap to the elevation of that plan view.

Manual X: A positive (+) or negative (-) distance (in the primary dimension " Units " or other units ).

Member Plane (self)

A member end can be pinned to a plane of its own member that end belongs to. In which case, it will appear under a heading that reads " Self " or " Member Plane ." A pin to a " Member Plane " or " Self " can be deleted by pressing the trash can button ( ) associated with that leaf.

Bind to plane of top flange: or .

In this example the plane that the member end is pinned to is the plane of its own member's top flange.

If this box is checked ( ), the member end you are editing is pinned to a plane that includes the surface of the top flange of that same member.

If the box is not checked ( ), the member end is not constrained by the top flange of its own member.

Bind to plane of web center: or .

In this example the plane that the member end is pinned to is the plane of B_33's web center. B_33 is the member that the end belongs to.

If this box is checked ( ), the member end you are editing is pinned to a plane that includes the web center of that same member. The plane will be a vertical plane, regardless of the rotation of the member, if " Ignore member rotation " is checked.

If the box is not checked ( ), the member end is not constrained by the web of its own member.

Ignore member rotation: or . This may apply when either " Bind to plane of top flange " or " Bind to plane of web center " is checked.

If this box is checked ( ), the plane

Member Plane (other)

A member end can be pinned to a plane of another member. Auto Pins can create such a pin, or you can create such a pin by pressing the " Add " button then choosing " to other member's plane ' then selecting that other member. A pin to a " Member Plane " can be deleted by pressing the trash can button ( ) associated with that leaf.

Bind to plane of top flange: or .

In this example, the bottom end of a column is pinned to the top flange of beam B_22 . The column's bottom end elevation will adjust when the beam's elevation changes.

If this box is checked ( ), the member whose end you are editing is pinned to a plane that includes the top flange of another member. The plane will be a horizontal plane, regardless of the rotation of the other member, if " Ignore member rotation " is checked.

If the box is not checked ( ), the member end is not bound to the flange of the other member.

Bind to plane of web center: or .

In this example, the plane that the member end is pinned to is the web center of B_25 . The left end of the horizontal brace is the end being edited.

If this box is checked ( ), the member end that you are editing is pinned to the web center of another member. The plane will be a vertical plane, regardless of the rotation of the other member, if " Ignore member rotation " is checked.

If the box is not checked ( ), the member end is not bound to the center of the web of the other member.

Ignore member rotation: or .

Member End Plane

Member ends can be pinned to each others end planes. You can create such a pin by pressing the " Add " button then choosing " to other member end's plane ' then selecting that other member's end. A pin to a " Member End Plane " can be deleted by pressing the trash can button ( ) associated with the " Exact Location " leaf .

-----  between Member XXX and Member YYY -----

Each of the two pins shown in this example are pinned to the same plane. The two beam's connect with a beam-to-beam splice plate connection.

Spliced Ends

Member ends can be pinned so that their members remain colinear to one another. You can create such a pin by pressing the " Add " button then choosing " spliced members ' then selecting the opposing member's member line. A pin for " Spliced Ends " can be deleted by pressing the trash can button ( ) associated with the " Exact Location " leaf .

-----  line from XXX to YYY -----

Auto Pins creates " Spliced Ends " pins that align the opposing ends of the supported vertical braces in an X bracing framing situation.


VIDEO Vertical X braces that frame opposite to one another have " Spiced ends " pins. A vertical brace to a beam-column is pinned to the beam with an " Offset from member line " of ' Half nominal depth '. When the beam's left and right " End elevation " are moved up, the X braces remain colinear and the brace to beam-column stays aligned to half the nominal depth of the beam. (Recorded in SDS2 Detailing , v2017.)

Even Spacing

-----  EvenSpacing on XXX -----

VIDEO " Even spacing " auto pins for vertical braces that are part of a truss ensure that the even spacing is maintained when the beam is stretched due to the grid line that beam's end is pinned to being moved. (Recorded in SDS2 Detailing , v2017.)

VIDEO Filler beams are added between two beams. Model > Members > Pins > Pin Add > even spaced members is used to constrain the beams to even spacing. (Recorded in SDS2 Detailing , v2017.)

With first / last spacing: or . Note in the examples below that the four member ends on members L_1 and L_2 are set to be " Spaced on member: B_7 " and that B_7 is one of the members that are stretched when B_7 and B_8 are stretched.

" With first / last spacing" (examples before and after Move/Stretch ):
" With first /last spacing" (even spacing only, before and after Move/Stretch ):

If this box is checked ( ), then " Space 1 " and " Space 2 " distances can be entered to ensure that the leftmost and rightmost members that are evenly spaced to maintain their distance to the left/right ends of the " Spaced on member ."

If the box is not checked ( ), stretching the " Spaced on member " will result in even spacing being maintained between the member ends of all members

Space 1: The distance (in the primary dimension " Units " or other units ) from the left end of the " Spaced on member " to the work point associated with the leftmost member end that is attached to the " Spaced on member ." This applies only when " With first / last spacing " is checked.

Example: In the example for " With first / last spacing " (above), the user could have entered a distance of ' s1 ' to " Space 1 " for the two member ends associated with member L1 . After the " Spaced on member " ( B_7 ) is stretched, the distance s1 would be maintained between the left end of B_7 and L1 .

Space 2: The distance (in the primary dimension " Units " or other units ) from the right end of the " Spaced on member " to the work point associated with the rightmost member end that is attached to the " Spaced on member ." This applies only when " With first / last spacing " is checked.

Example: In the example for " With first / last spacing " (above), the user could have entered a distance of ' s2 ' to " Space 2 " for the two member ends associated with member L2 . After the " Spaced on member " ( B_7 ) is stretched, the distance s2 would be maintained between the right end of B_7 and L2 .

Spaced on member: The member ( pcmk [ num ]) that the member end is spaced on. Press the " Select Member " button if you want to select a different " Spaced on member ."

Tip: If you want to change the " Spaced on member ," you should multi-edit and do it for all member ends that are spaced on the " Spaced on member ."

Example: In the example for " With first / last spacing " (above), the two member ends associated with L1 and the two member ends associated with L2 are all set to " Spaced on member : B_7 ," resulting in the spacing being maintained when beams B_7 and B_8 are stretched. Since the two beams are stretched equally, the same results would have been maintained if all four ends were instead set to " Spaced on member : B_8 ."

" OK " can result in serious changes to the member whose end you are editing.

The member whose member end you edited may undergo Process and Create Solids .

The member may be relocated, for example, due to your pinning it to a particular view or member or due to your entering an offset.

Settings such as " End elevation " on the member's edit window may change.

If " User " was unchecked before you opened this window, you may find after pressing " OK " and re-opening this window that the pins associated with this member end are set to " User ."

"Cancel" (or the Esc key) closes this window without changing any of the pin settings associated with the member end(s) you are editing..

"Reset" undoes any changes made since you first opened this window. That is to say, " Reset " populates this window with the settings that were originally entered to it when you first opened the window. The window remains open.
