Simple tip for making custom trim profiles with a radius

Anonymous
Not applicable
Say you want to do a masonry arched opening and you want to do a gothic style stone casing with an special profile. THe casing needs to curve around the top of the arch. Create the profile (fill pattern) in the profile manager and save as beam - the trick is the profile needs to be lying on its back, not upright. Go to a plan view and select the custom beam profile and draw the profile. Beams can curve in the x-y axis only so curve the beam radius to match the radius of the arched opening. Once you have done this you have a curved beam lying on the ground with the profile you want for your casing.
Now convert the beam to a morph by right clicking and selecting the morph conversion option. Once it is a morph you can go to the 3d view of the beam and select it then rotate the morph 90 degrees upright. then just place it up against your arched opening.

Or you could do it with a revolved shell.
The advantage of this is you can edit the profile if you need to whereas once it is a morph this is not so easy.

There is a youtube video on the archicad channel where they are trimming walls with 0 thickness shells to create the arches in Wells Cathedral.

The curve resolution of the shell might not be what you are looking for, but as pointed out by Barry, they are much easier to modify than morphs.
