Trim to Roof – Make it useable

[snow]

Hello friends,

since some years we've this further development of once 'crop to single roof plane' and SEO to crop all kind off elements to roofs… with this enhancement to react to intersection priorities.

But in most cases it is not possible to use this function, because every part of elements to trim which is not covered with the trimming roof, gets eliminated.

(In the background the desired result, done with SEO)

So the whole 'Trim to Roof'-option remains useless. In most buildings we plan we don't have just a rectangular roof plane.

I would be a great thing to use trimming in many more situations.

Thank you for fixing it.

Yeah, I would find it a lot more useable if it did not crop everything to it's boundaries.

Tip: What you can do in such a case is place another, a flat Roof in the Model, which will trim the top of the "missing Zone portion". The idea is that the Roof should overlap the Zone in plan view so its Trimming Body is larger than the Zone. Then select the two Roofs, and use the "Merge Element" command on them. When two Roofs are "merged", their Trimming Bodies are merged as well and will give you the desired result. You can activate the View > On-Screen View Options > Trimming Bodies toggle to see how the Trimming Bodies of the Roofs change when you merge them.

Thank you, Laszlo, for showing this workaround.

When I wrote the wish, I thought it will work such way... but I'm really not satisfied with this basic behaviour...

It can get quickly very complex, especially if you have to manage walls, cropped to different roofs and parts of it without any cropping.
