How to make Windows on Curved Surface

arch window house.3dm (5.0 MB)

The model I have attached has an arch window cut out from where I want to put a window. I want to add a windowpane and also frame, but if I were to extrude a closed curve to create the pane it doesn’t work. How would I make the pane and then also add the frame outside the edge of the cutout?

Thank you!!

The approach I took was doing a Sweep2 on the two sides of the window - the rails being the top arch edges and the bottom edge.

From there, making the surface that joins the two sides of the window by doing yet another Sweep2 by sweeping a line created connecting the two corners.

Hopefully this video demonstrates well enough.

Hi Jacky -

I’m not sure what it is that does not work.

I’m assuming that you want to have a planar window.
I’d start by making a box that is as deep as it gets while still being within the wall:

The next steps then involve a bit of scaling and cutting… In the attached, I’ve created objects for each step I took, you can step through them by turning layers on and off…

For this kind of thing, I’d build the window without the curve and then use Pascal’s ProjectObjects tool.

Thank you soo much!! This was super helpful.

Would you perhaps know how to make a basic window frame for it?

What I would do is DupeEdge the outer edges of the window frame, join the resulting curves (at least I think they don’t autojoin), do an offset, and then extrude the original and offset curves.

People much smarter than me might have a better way.

Sorry, what did you mean by this? Cause if I were to try offsetting the joined dupeedge, it would come out weirdly?

My attached file shows a curved wall and thus the curved window pane. So I was wondering how to make the window frame which would also have to curve the building’s surface as well. If that makes sense.

The idea I had was offset the duped edges, extrude, back the extrusion in the appropriate amount, and if desired, do a boolean difference to remove the bit that’s intersecting with the house.

Hi Jacky -

I don’t think that curved window panes make sense, but, if that’s what you want, you’d do this in a completely different way.

I don’t know how you made the window cut-outs for the walls (and don’t know why they aren’t oriented toward the center of the building…) but, at some point, you had an object (or different surfaces, curves, …) to make those cuts. If, at that point, you had split the walls instead of trimming, you would have had the surfaces for the frames.

In the attached, I recreated that cutting object and used that to make a frame and a window - turn layers on and off to see the process step-by-step.
