Turnbuckle Edit window
( Modeling > F2 > " 
Misc steel " > " Turnbuckle ")
Selecting " Turnbuckle " as the " Miscellaneous steel " type adds a custom member with turnbuckle material to a 3D model.
The Turnbuckle custom member is a superior alternative to " Miscellaneous -- Turnbuckle ."
The edit window of this member features material and member options on the same window.
Its " General settings " include " Break apart " and " Rotation " which are not available for the legacy miscellaneous member.
Member operations such as many of those found on the Model > Member menu in Modeling can be performed on this member, and you can add custom components to it.
The " OK " button is disabled (grayed out) to indicate a validation error. Hover the " OK " button with your mouse pointer to get a listing of settings you need to change on this window. When all settings are valid, the " OK " button is enabled. 
Red-colored highlighting identifies an entry that is invalid. You need to change that setting, or you will not be able to close this window using " OK ."

Add a turnbuckle :
1 . A turnbuckle miscellaneous member can be properly located and rotated even in an isometric view. Before adding the member, be aware of the following:
2 . To add a turnbuckle miscellaneous member (in Modeling ):
Alternative 1 : Press F2 > check the box for "
Alternative 2 : Choose Model > Member > Prompt for Member Type > check the box for "
3 . Locate - Repeat - Return mouse bindings become active, and you are prompted to locate the turnbuckle's work points. Two work points are required to lay out a turnbuckle.

3a : Select the appropriate Locate option.
3b : Left-click ( Locate ) at two different on-screen positions to define the member line between those two points. The first work point you enter when you add the turnbuckle defines the left end of the member. The first point represented as an exact point after step 4, when the member is actually generated in the model. The second point determines the orientation of the member line with respect to the global coordinate system.
The first point that you locate is identified by an origin symbol . The origin symbol also tells you which end is the member's left end. If you Model > Member > Isolate > ... a turnbuckle miscellaneous member, you will find that the member's MAIN VIEW shows the member's origin symbol (
) to be to your left. This is true for any miscellaneous member -- even if the origin symbol for the member is to your right in a plan view. The MAIN VIEW in member isolation directly correlates to the main view of the miscellaneous member's detail.
Best practice when adding a miscellaneous member in a plan view is to input the member from left to right or from bottom to top. That way, when you add a grid line from left to right, the near side of the member, as determined by the location of its left end , will be the side looking toward the bottom or toward the right of the screen.
4 . The Turnbuckle Edit window opens. On it are settings for the turnbuckle that you are adding.
4a : Enter a " Section size ," a " Left thread type ," and a " Right thread type ."
4b : Press the " OK " button at the bottom of the window to apply your settings and close this window.
Note: The default settings on this window are those of the last turnbuckle miscellaneous member added or edited in this session of Modeling . Even if all you do is double-click a turnbuckle member and press " OK " on its edit window, its settings become the defaults for the next-added turnbuckle miscellaneous member. You therefore only need to make changes to those settings which are different for this member.
5 . If User and Site Options > Modeling > " Process after modeling operation " is ' Process and create solids ', the new turnbuckle will have automatically undergone all phases of Process and Create Solids and will show up in a solid form . If that option is ' Process ' or ' Do nothing ', then the member line of the turnbuckle you just added shows up on screen in stick form , and you will have to Process > Process and Create Solids in order to have the member piecemarked and able to be displayed in a solid form. Do one (1) of the following:

Alternative 1 : Move the mouse pointer (
) and middle-click ( Repeat ) to lay out a turnbuckle just like the last one beginning at the point where the point location target (
) is at. The X, Y global axes location of the repeated turnbuckle will begin from the located repeat point (where the target is at). The turnbuckle's Z location and other settings will be that of the last-added or last-edited turnbuckle.
Alternative 2 : Follow these instructions beginning with step 3 to add a turnbuckle with different settings than the one you just laid out.
Alternative 3 : Right-click ( Return ) if you are done adding turnbuckle.

Section size: Any turnbuckle material section that is listed in the local shape file . You must enter a section size in order to add a turnbuckle.
To enter a section size: You can type in the section size that you want, or you can press the "file cabinet" browse button (
) and double-click any section that is on the list of available turnbuckles in the local shape file . Validation does not let you enter a section that is not available in the local shape file.
The following can read the choice made here when " Main material " is ' SYSTEM ':

Report Writer: MemberMaterial.Material.SubMaterial.MaterialFile.SectionSize
Left thread type: None or Left handed or Right handed . If, for example, the end of the round bar that is to be fitted to the left end of this turnbuckle uses ' Right handed ' as its " Thread type ," you will probably want to select ' Right handed ' here.

Report Writer: XXXXX . LeftThreadType
Right thread type: None or Left handed or Right handed . If, for example, the end of the round bar that is to be fitted to right end of this turnbuckle uses ' Right handed ' as its " Thread type ," you will probably want to select ' Right handed ' here.

Steel grade: C-1035 or F22 Class3 or etc. The grade of steel for the turnbuckle.
Setup: If the grade of steel you want is not shown as a list box (
) for this field, you can use Home > Project Settings > Job > Material Grades > Turnbuckle / Clevis / Pin Grades to add it to this list.
The following can be used to track the choice made here when " Main material " is ' SYSTEM ':
Bill of material: Steel Grade
Advanced Selection: MaterialGrade
Parametric module: MaterialGrade

Standard detail: None or a standard detail name . To apply a standard detail, you can type in the file name of the drawing (if you know it), or press the "file cabinet" browse button ( ) and double-click any job standard detail or global standard detail that is on the list.
If ' none ' is entered here, then no standard detail will be applied on this end of the miscellaneous member when it is automatically detailed .
If a ' standard detail name ' is entered here, the next time you auto detail this miscellaneous member, the reference point of the standard detail will align with the input work point on this end of the member, and the standard detail's bill of material will be combined with the member's bill of material. The detail is placed on a layer that is named after the standard detail plus a "_L" or "_R" suffix.
