Canted wall w/ window workaround

Anonymous

Hello, I've looked at suggestions made for creating windows in canted walls and I'm having trouble getting the correct results.

Originally, I used a canted wall and found that it's reference wall's windows were only appearing as openings.. So then I copied the reference wall and saved it as a GDL, went into the 3d script and added the cant angle to ROTX. There are two prompts for ROTX, so I tried adding the angle to both. What I end up with is a perpendicular wall w/ a canted window....exactly the opposite problem of what I started out with, and still not right. Any advice for me? I'm new to this GDL stuff... perhaps I'm modifying the wrong line in the script?

Using two roof planes in a conventional wall, use SEO to trim to the angle you require.

i think i understand, but something didn't work. i drew an really thick wall. then drew two roof planes at the angle that i want for the cant of the wall. i tried to do the seo with the intersection mode. it just completely erased the wall (the roof planes were both bigger on all sides of the wall). then i tried doing wall trim at a time, one with downwards extrusion and the other with upwards, so that i could get the sliver in between. it still didn't work. did i totally miss the boat on this?

it appears so.

here's another view of the assembly.

Your attempt with intersection mode got me thinking. Using Intersect in SEO means your canted wall will remain only where both the fat vertical wall AND the sloping roof co-exist, so if you are using intersect SEO use a single roof exactly where you want your canted wall. Turn the roof's layer off - you should get your result.

Of course if you want different slopes inside and outside your wall, two cutting roofs will be necessary.

i'm not sure what in the world i am doing wrong. i've attached an image of the way i'v been trying to do it. the big grey thing is the fat wall with the two planes being roofs. i need to end up with the sliver in between the roofs. i've tried everything i can think of. if anybody can help, you'd be helping me out so much! thanks

SEO the lower roof "subtraction with downward extrusion"

SEO the upper roof "subtraction with upward extrusion."

i've tried that so many times. each with different combinations, and orders of picking things. the closest i can come to getting the wall is this image. i have even tried making the roof plane on the left side so thick that it totally covers up the part of the wall i don't want.

Are you selecting the wall as the target, then deselecting it before selecting the roof as the operator?

yep, the wall is the target. then deselect and select the roof only as the operator...
