Trimming roof problem

Anonymous — Tue, 23 May 2023 12:24:58 GMT

Im have problem with trimming roof with Wall, bot with same composite structure. The problem is that last skin (plank Wood) wont connect propertly. The insulation (intersection priority is menor tan inter. priority of Wood), is visible in 3d. I want connect plank Wood and hide insulation. How i can solve this??
Please help, it is for my final Master work.
Thank you!

The capture of 3d is in atacch.

For one thing, it looks as if you don't really want those materials to join anyway. It would be very unusual if the building to be constructed like that - the roof insulation is probably not going to be monolithic with the wall insulation. SIPS ? Also, they are not the same composite. Roof appears to have 3 materials and the wall looks like it has 4. ?

What are the specific materials you are building the roof and the wall with?

Yea, in this image is diferent composite, but the same thing is happening with same composites. The insulation is monolite, to avoid the termal bridges. Is natural insulation...

This is an issue similar to Wall Intersections in Floor Plan, where there are similar cases where the automatic Priority Based Connection does not give the desired result.
Please see the offered solution there:

In your case we can do something similar: model the whole problematic Wall-Roof intersection using a Complex Profile Beam, the horizontal bottom of which will touch the top of the Wall below it, and the vertical left side of which will touch the Roof.
If you do it right, these joins will be seamless and you will not see undesired lines in 3D on their surfaces.

Thanks. I will try with profiles. But in the future hotfixes and versions we waiting for this issue solved 😉

This is not a problem with the software, it is a problem with the methods of modeling something that probably is not even constructible.
If it is, I would like to do it on my next project.

In any case, if the roof and the wall composites are the same, there are several tings you can do the change the graphic display on the edge of that roof to match the material of the wall. One of the things you many not have tried yet is to do this with Solid Elements Operations. There is a setting for "Inherit from Operator" that may do the job.

There is always some way to get what you need in ArchiCAD -- if you are clever

are you using SIPS ?

By the way, the update for 19 is out for UKI and INT versions.

Thank you. I cant do with this option that you mentioned.. I will do thing en Photoshop....

Time is short I am sure. I hope everything goes well with your presentation.

In case you have time later, here is a little video that shows how you can make the roof composite join a wall composite with a perfect clean up. http://screencast.com/t/AlaTFT5sqK0

Thank you very much... It is nice to see good people.. Actually I'm working so hard, and I have one mount and 15 days to terminate the work. Its a lot of things - to prepare the buildings, do graphic design, write texts... but succes is guaranteed
