Command line: 2DREPSTR
Creates a two-dimension representation from a three-dimensional model. This command removes hidden lines and retains layer and color information. It can work in model or paper space. In model space, the 2D representation creates as an unnamed block that does not show up in the CAD platform Insert command. When you use the command in model space, the created block displays at the zero elevation of the selected object. If you do not see the 2D block, then the CADWorx object is overlapping the block. To see the 2D block you need to move the CADWorx object. CADWorx does not create a block when you use the command in paper space.
When you XREF an item into a drawing, check that the Solid History of the object is set to None before running 2DREPSTR.
An alternate command, 2DREPHSTR is also available. This command exports the hidden lines from solids to the 2D representation. All other features of this command are similar to the 2DREPSTR command.
Solids
Generates 2D representations of native CAD platform 3D solids.
sOlids-and-centerlines
Generates 2D representations of native CAD platform 3D solids and copies selected CADWorx piping and structural center lines to the 2D representation.
soLids-and-lines
Generates 2D representations of native CAD platform 3D solids and copies selected CAD platform 3D Polyline, Arc, Circle, Ellipse, Leader, Line, Polyline, Spline, and Helix to the 2D representation. This includes CADWorx piping and structural center lines.
Centerlines
Copies selected CADWorx piping and structural center lines to the 2D representation.
cEnterlines-and-lines
Copies selected CADWorx piping and structural center lines to the 2D representation and copies selected CAD platform 3D Polyline, Arc, Circle, Ellipse, Leader, Line, Polyline, Spline, and Helix to the 2D representation. This includes CADWorx piping and structural center lines.
-
This command only processes native CAD platform solid and line entities that are typically created by CADWorx Structure. This command does not process any custom solid or line entities that are created by other add-on CAD applications.
