Curved and sloping window transom

Anonymous

Good morning

I am trying to model a curved section of curtain walling, the top transom also needs to follow the line of a sloping soffit. Im new to ArchiCAD, I can form my transom using a complex profile and the wall command. But can not find a way to slope/ angle it so that in elevation one end is lower than the other.

Any thoughts?????

Cut it off by a conveniently placed roof plane.

Use Solid Element Operations to cut off what you don't need.

Use the complex profile with the Beam tool instead. It will slope.

The sloping beam tool will work with a straight profile, but i need to curve it in plan. all i have managed to do is draw what looks correct in plan but in elevation it is a series of beams all at the same angle. Not a continuos slope as needed.

Also any ideas on how to trim a beam to a non perpendicular column?

You're right. I hadn't tested this. The beam tool doesn't bend. If you place beams along a curve with the magic wand/space bar, it segments. And instead of continuing upwards, each segment starts at the same level.

I you manually raise the level of a segment to match the previous, they will join in 3D and section, but it will look a bit weird and the joint will be visible. See attachment.

I guess itäs doable this way, but Djordje's tip of cutting a curved wall with SEO or trim to roof is pobably better. There is a caveat to that one too. The cut will be a plane, not the spiral ramp that you really need. Perhaps you could use the spiral ramp object in the library?

Otherwise, your best bet for this is the add-on Objective! Try it!
