Command -  Prb_LineCut

     

This command allows us to modify the start or end of a profile by shortening or extending it, but also by adding non-perpendicular cuts to it.

At the command line prompt, the following dialog will appear:

Here there are 2 options:

  • To lengthen or shorten the plate or profiles
  • To cut the plate or profile along a line


Shorten/Lengthen:

Start Beam

End Beam

Both Sides

First you enter the distance to be shortened or extended. A positive value will extend the entity, while a negative value will shorten it.

Choose from To Point, Begin beam and End beam. 

To point - you have to indicate a reference point on screen and the beam will be cut to that point. 

Start beam will shorten/lengthen the beam according to the entered value. The start beam position is the origin of the entity (where the triangle is located)

End beam does the same as Start beam but at the opposite end of the beam.

Both sides - will shorten/lengthen the beam at both ends


Cut using a line:

Part to keep -        Longest: Will cut away the shortest section, keeping the longest measured from the cut line

               Shortest: Will cut away the longest section, keeping the shortest measured from the cut line

               Both: Will cut the beam or plate at the cut line, keeping both sides

               Select: Will allow you to manually select which side to keep

Longest

Shortest

Both


Orientation cutting plane:

      • Current UCS: Cut along the current work plane (UCS).
      • Current view: Cut according to the current view.
      • 3 points. You are requested to set/select 3 points. The cut will be according to the plane defined by these points.

Tolerance: You can also set an offset between the line and the profile.

Shorten/lengthen the entire edge against the line when enabled this will shorten or extend the profile during the cut operation \


This is an example with the option Shorten/lengthen enabled :


This is an example with the option Shorten/lengthen disabled :


This is a second cut operation on the same profile with the option Shorten/lengthen disabled :

With the Shorten/lengthen enabled it would not be possible to achieve this miter.
