chamfered or detail cut on beam ends

What is the easiest way to model beams with chamfered ends or details cut on the beam ends?
Thank you,
John

Build a group of complex profile walls to either auto-cut or SEO the beam end. Think of the group as a special trimming object.

In this image, I've overlapped several complex profile walls to step the cut.

Aloha Dwight,
Thanks, I'll give it a try. First I have to figure out how to make a complex profile wall. Would you be so kind as to give me a hint or instructions on how to do this?
Once the end of the beam has been cut this way can the beam be moved around, copied, raised and lowered? Can the angle and rotation of the beam be changed?
Thank you,
John

The principle is to EXTRUDE a shape with the wall tool.

1: use a fill shape to make a complex profile shape, assign it to wall use [distinct from wall, beam and column uses -to keep the complex profile choices manageable for each tool].

2: Use it in a wall ACROSS the axis of the beam. If you have the wall/beam priorities correct, the wall automatically cuts the beam. But you can't see this until you make the wall into a wireframe layer. If you don't get the priorities right, use the SEO function to trim the beam.

3: You'll edit the fill to change the shape of the trim and apply it to the conditions you'd like to edit.

4: Group these elements to make them travel with the beam.

See Eric's article: the three bunny wunnies have a picnic

Now, if having the construction drawing benefits and behaviours of a real 'beam' isn't important, you can make the entire beam element from a wall complex profile element without any trimming. You'd use a fill derived from the building section, copy the fill to the complex profile editing window and then draw ACROSS the axis to make the wallbeamthingy.

This approach solves numerous modelling challenges in Archicad where the SECTION PROFILE defines the shape of the sideways extrusion for ballustrades, medallions, logo signage - whatever!!

Oy Vey!!! Experiment, already!!!

Well I would have to argue with Dwight on this one. but with a caveat. This is probably the easiest way to do it within AC without any added tools but using the OBJECTiVE tool add-on makes it dead simple. You can easily rotate, change pitch angle etc. I use this add-on more than any other except perhaps CadImage's Door & Window tool. My 2 cents.

Check THIS ArchicadWiki article... half way down.

Thanks everybody,
I'm trying Objective right now and it was easy and worked great.
Mahalo,
