Modeling curves into a wall

[hoseinasadi]

Hi guyz, ive been struggling with modeling curves and generally round things into walls(surfaces) without using boolean and we all know they pretty much mess up the topology. anyway heres a ref image and id like to create that nice arc thingy on top of the window. any tips please ?

This sample uses turbosmooth, but hope it helps.

thanks for the reply , could you please tell me the steps youve done to get the final result tho ?

Just draw your wall in an ortho-view (top ,front, left). Use splines and be sure to use a higher interpolation value for the splines. When that is all set, just attach your lines, extrude, and place your wall.

Corey's method is good for arch walls. the one i showed uses turbosmooth so you'd end up with more polys than you may want for a wall. but its shown here:

im not sure what u mean by "higher interpolation" , but here's what i got following ur instructions. tho im not really happy with the way it looks , too many individual pieces i had to attach to get this, i kinda think this is not the way pros do it.

in the spline parameters there is an interpolation rollout. you can increase that value to make an arc "smoother" (more segments).

it'd be great if i could just go ahead and cut this thing out of a box/surface without creating all those splines and attaching and stuff. do you know of any particular technique i could use?

use the method Corey suggested to create the wall... make it a separate object from the window. wall rectangle + window perimeter spline > shell/extrude modifier.

 

 

in this image, the arc segment's interpolation =12

im such a noob! how do i get the window cut thru the wall just like ur example?

[Jose Negrete]

the wall has to be a rectangle spline that you can attach your window perimeter spline to. once those two splines are attached together, add the extrude modifier

i created a rectangle as for wall , and created the window frame using arc+line and then attached them together, i then attached the window frame to wall (rectangle), applied extrude modifier and here's what i get , wonder what the problem might be ...

make sure all your window spline verts welded

[hoseinasadi]

thanks alot ,as u said they hadnt been properly welded. one more question tho , how can i model complicated curves like this ? again without the use of boolean.

Dude, that's already two questions for one thread. Check the forum rules for it might be not permitted.

 

As for the original question, if you make tight solid meshes, and I mean welded vertices, no overlapping faces or edges, etc. (which you can check with the xView tool), you can make whatever booleans you want without messing up anything. Trust me, I know because I do it all the time.

Try using proBoolean, seems to work better.

 

Still, for modeling an arched opening in a wall, indeed there are many ways to do it.

that image has a lot going on, i would try to outline profiles in those coffers in order to get a better sense of the pattern and the shapes involved.
