Trim Element to Roof shows the element geometry...

How to prevent showing the wall cut when using the Trim Element to Roof?

The building material strength for the top roof surface needs to be stronger than the building material strengths you use for the wall.

where in the "help module" is this explained or what do i search for? when i look at the building materials interface i don't see the roof that i used and trying to eliminate the wall peeking through? i tried to change the numbers in the layer interface to increase roof from 1 to 5 and wall partitions from 5 to 1 but no changes.

Select the roof, right mouse click and choose the option to 'edit selected composite'.

This will show you the building materials you have used in that composite.

Or even better, select a roof plane and a wall and open the building material settings dialogue.

You can then arrange the list by building materials used (they will be highlighted) and you can compare the strengths of all of them.

The one used for the top surface of the roof need to be stronger than those used in the walls.

When you 'trim', the shape and position of the elements will form the overall trim and the stronger building materials will cut the weaker ones.

Hey @Barry Kelly, shouldn’t changing the crop zone to the underside of the roof fix this problem before changing material strengths ?

When you crop or trim, you can choose to keep the wall above or below the roof.

But I am pretty sure in either case the intersection between the wall and roof is still there and building material strengths come into play.

I think only Solid Element Operations will truly cut the wall at the top or bottom surface of the roof.

Hi @Zdenko to help us all understand how to do this operation with various methods and the resultant effects, please watch this excellent video tutorial. For the @Barry Kelly material strength method please watch the video to the end. Enjoy !

hi barry - after messing with the building materials interface it solved my problem and wanted to say thank you VERY MUCH! this learning lesson was worth its weight in gold! now on to stairs 🙂

No worries, James Badcock from GS has some other great tutorials that have helped me out greatly particularly the ones on using the railing tool. He has others on YT that I have subscribed to as well. So he deserves all the credit.

ok so i am back at it and quite frankly, annoyed, went back to that video which imo was of no value with my current situation. went to the help and it appears i can't replicate what help is showing as an example. the video basically shows me simply trying to trim the walls to the main roof and then was going to go the dormer roof to trim those walls.

please disregard figured out my sequence was the opposite!

need a little guidance on 2 items one related to topic and the other not. would like to clear out the main roof within the loft roof and you can see looking through the window that the main roof is visible and trying to figure out how to remove. second question is in regards to the sliding door shown in lower right of image. can't seem to find how to make the sliding door show clear glass in the object settings interface.

Re: Trim Element to Roof shows the element geometry...

Barry Kelly — Thu, 30 May 2024 00:59:34 GMT

You could select roofs, right click > Connect > Trim Elements to roof shell, but the hole will be the size of the upper roof.

I would just use the pet palette option to cut a hole in the main roof.

If that is a door and not a window, check the MVO settings for detail level in 3D - may not be 'Full'.

Barry.

thanks for the hint and mvo was good but did find the glass clear selection under leaf surface to solve my problem. still working on roof and will try your recommendation if unsuccessful.

@Zdenko, Thanks for posting the cut a hole in the roof and create an atrium video.

Have you seen this video about using a predefined dormer from the library that auto cuts into the roof ? That’s the easiest way to do it but taking the long way you learn to use the program better.
