Command name : PrB_Extrude

 
This command allows the creation of a profile with a custom section without the need to save the custom section in the library first.
The custom section and the new profile will both reside in the same drawing.
The command will first ask you to select the 2D polyline(s) that should be used as the section for the new profiles.
Multiple polylines can be selected for the creation of holes or for multi-sections. The result will still be 1 profile per extrusion.

The command will then ask the model lines onto which the profile should be created. At this stage you can press <Enter> to create a new line with the help of 2 points.
The model lines do not need to be close to the 2D polylines. The section will be moved and rotated to the position of the model line(s). However, placing the section polylines at the start of the path provides more control over initial rotation.

Afterwards you will still have the opportunity to position and rotate the new profile around the model line, just like any other new Parabuild profile.
