how to put an end bevel/mitre on a complex profile beam

[Anonymous]

Archicad 14:
Say I create a beam that is half round using the profile editor and create a beam of x length in plan. How can I now put an end miter of say 45 degrees on this? On columns this is somewhat easier, one can trim to roof. However, with a beam it can't seem to be trimmed. I tried trimming (with trim) tool to a wall segment placed at 45, but that didn't work. Is there a workaround?

Trim to Roof works just fine. I frequently use this technique to handle complex profile eaves.

If you are having issues with it, check your priority settings.

I'm not sure just what you are trying to achieve here.

Beams will automatically miter at their intersection. This only works cleanly if they are the same profile of course. If you are looking to force a miter different than the automatic one (such as the vertical miter at an eaves/rake joint) the trick is to overlap the sticks and use SEOs to do the trimming. I use a couple of slabs as the cutters and put the on a hidden layer.

If you are looking for a self-return just make sure the reference line of the profile is not on the back face so the return is not zero length (you can make it long and trim it but this is a kludgy solution).

If you're looking for more freedom shaping beams or other objects, try OBJECTiVE. You can cut objects using a tool very much like ArchiCAD's split, and the cut remains constant no matter how you subsequently rotate, stretch, or further split the object. Referring to the attached image:

• 1. Select the object to cut and click the menu OBJECTiVE > Tools > Split. Then trace the line where the object is to be cut, and click on the side to remain selected. You can retain the offcut or delete it.
  
  2) You can then split the object again, shaping the end as required.
  
  3) The same applies in the elevation view. You can also rotate the object (using OBJECTiVE > Tools > Rotate to create more complex shapes.
  
  4) The finished result in 3D.
