The Position and Match Marks screen lets you define how CNC marks are positioned on member main material. These marks can then be used in the shop to guide the fastening of connection materials to the member. The selections made here also determine the dimension points on member details for system connection shear tabs, stiffeners, gusset plates, etc., even if you do not generate CNC marks on member details.

Perpendicular shear tabs: Center of plate or Left face or Right face or Framing face of plate. This applies to moment and non-moment single-plate shear connections. It also applies to a shear plate that connects a vertical brace gusset plate to a column. The left face is the surface of the shear plate that faces left on the supporting member's detail. The Framing face of plate is the face of a plate that attaches to the supported beam.

Column flange stiffener plates: Center of plate or Top face or Bottom face or Outside faces of plates or Inside faces of plates. This applies when the box for Design for stiffeners is checked for a bolted or welded moment connection to a column flange.

Connection stiffener plates: Center of plate or Left face or Right face. The example shown below is the vertical stiffener for a plate seat. This also applies to stiffeners for angle seats and end plates. The left face is the surface of the plate that faces left on the detail for the member that the stiffener plate shop welds to.

The match mark on the stiffener is shown here as green. The position marks (Center of plate) are black and placed at the edges of the plate.
Clip angles: Corners. This applies to single and double clip angles. The placement of position marks on clip angles depends on whether the clip angles are set to be Attached to the Supported or Supporting in the shop.
Supported
Supporting
Add match marks puts a match mark 1/3 of the way down (or up) the clip angle and another mark on the supported beam. The match mark on the beam is red in this example. The match mark on the clip angle cannot be seen in this view since it is on the face of the clip angle that frames to the beam. The position marks (Corners) are black and placed at the corners of the clip angle. All marks are black in the model.
Add match marks puts a match mark 1/3 of the way down (or up) the clip angle and another mark on the supporting member. The match marks on the column are red in this example. The match marks on the clip angles are not shown in this view since they are on the framing faces. These two clip angles share the same piecemark, and that is why their match marks do not align.
Connection seats: Center of plate or Top face or Bottom face. This applies to plate seats. The top face is the surface of the plate that faces up on the detail of the column that the seat shop welds to.

These marks can then be used in the shop to guide the fastening of connection materials to the member. The selections made here also determine the dimension points on member details for system connection shear tabs, stiffeners, gusset plates, etc., even if you do not generate CNC marks on member details.
A CNC mark is shown as an X on members in Modeling that are displayed in a solid form. To get CNC marks on member details, Show marks on details during Detail Members. CNC marks are always shown on the details of submaterials. The location of CNC marks also affects dimensioning on member details.
For CNC with DSTV, a good alternative to position marking is to set Placement lines to All submaterial and Line style to Corners and Scribing block type to BO. This will get you CNC marks at the corners of all submaterial.
When position marks are applied to materials using this window (prior to CNC), they will affect piecemarking. If they are applied when the CNC file is generated (as described in the previous bullet point), piecemarking is not affected.
Settings applied to the Position and Match Marks screen are for your current Fabricator. A different set of settings will apply when you Change Fabricator.
