Command input:
ath_obj_project
With this command you can generate orthogonal, two-dimensional projections of objects, such as standard parts, semi-finished products and metal sheets.
When you execute the command, the following appears:
Input request 
Select objects:
Select the objects from which you want to generate an orthogonal projection. This input request is repeated until you terminate the object selection by pressing the Enter key.
Specify base point or [Adopt/?]: <Adopt>:
This option appears when you have selected a sheet metal section, as sheet metal sections have no insertion point.
Specify the base point for the projection.
With Apply, use the starting point of the first sheet limb as the base point.
Specify the side and starting point for the projection or [?]:
Determine the side and starting point of the projection.
The specified point determines the direction of projection as well as the distance of the projection to the selected object.
With the option ? you call the help.
Specify bar length or [?] <xx>:
Determine the bar length of the projection.
This input request only appears when the selected object is a profile section (standard part or semi-finished product). If the selected object already possesses a projection with length, then this length is used.
Note 
If you select several objects with different alignment, subsets of the objects are found which possess a common perpendicular. The projection is executed for the largest subset.
The original and projection are coupled to one another. This means that: If you modify a projection by a double click, all coupled projections are updated. This also applies to the display options (e.g. axes and thread lines).
Length changes, e.g. by stretching, are transferred to all linked projections.
Linked projections can be released with the Group Explode command.
When you change the position of a projection (e.g. rotation or displacement), this has no effect on the coupled projections.
During evaluation in projects or during Parts count, projected objects are treated as one.
Similar to 3D bars, you can also cut 2D projections of profile sections.
Similar to 3D bars, you can also slice 2D projections of profile sections.
Projections of sliced or trimmed 2D projections cannot be further sliced or trimmed.
You can convert the projections to solids. All blanks are retained.
