Editing 3D Warehouse Component

Hello all,

New here to the forum, and to sketch up - wondering if anyone can help! Hopefully I have found the right category.

I have downloaded a PVC Window from the 3D warehouse, and am struggling to make changes to the window to suit my particular window aperture sizes.

I want to increase only the size of the glass, as the frame etc around it should remain the same, regardless of window size. So when I scale, it alters not only the window to the correct shape (great) but also increases the size of the frame etc (bad!).

When I explode it, I lose some detail i.e. to the cavity spacer bar.

Can anyone help? I have tried to upload my sketchup file however its saying it is too large. Any ideas?

Thanks in advance. Chris.

Without seeing the actual component, it’s a bit of a guess, but typically, you should be using the Move tool instead of Scale. You’d need to open sub-components or groups for editing, select the part of the frame that needs to move and then move it the required distance. It’s actually quite simple to do if the model as been made correctly.

Before doing that, though, check to see if it’s a Dynamic Component. It might be in which case you might be able to set the desired size in the Dynamic Component Component Options window.

This is the component if this helps?


How large is the opening, then? And if the width is different, do the side windows remain the same width and only the center window gets wider?

1600mm wide by 1028mm high.

I edited the component first though (deleted the central panel - see photo


Ah… So no center light?


Not sure if I bodged the edit, but basically drew a plane through the frame, deleted what I didn’t need, mirrored it and reattached it! :confused:

No. I don’t think you bodge it at all.

So here’s the first part. I set out guidelines off the center line of the window 800mm out so I can work from the center out. Then I opened the frame component for editing, selected just the geometry at the side and moved it. You could, if you knew the exact move distance required, enter the move distance instead of using the guidelines.

Then for the windows themselves, you only need to edit one since they are instances of the same component. And since the right hand one was flipped to make it a mirror image, this part is pretty easy. Open the frame component for editing and move it the same distance as you moved the outer frame. To make that easier, I had added a little tick mark on the outer frame which was in line with the corner of the inner frame. Then I was able to move the corner of the inner frame to the tick mark’s new location.

Repeat the process for the sill parts and then adjust the height. You’ll want to do this with Hidden Geometry on to avoid distortions. It may seem like a lot of work but when you figure out the proecess, it goes quite quickly. I have on more than one occasion created a new piece of furniture from a different furniture model when all the joinery and other details were done.

Thanks for this Dave.

I’ll give it a go and let you know how I got on!

All done, so thanks for that. The only thing I’m stuck on now is increasing the projection of the window sill. I am unsure what the dotted lines are, but to increase the projection I have tried to copy these further out, but the sill ends up being see through.

Can you upload the window component as you have it after editing so I can take a look?


Its not allowing me to upload the sketchup file as it says its too large (6.5MB).

Is there another way?

Go to Window>Model Info>Statisitcs and click Purge Unused. Does that get the file size down? Otherwise, upload it to the 3D Warehouse or Drop Box and share the link.

Here we go.Sketchup File.zip (2.1 MB)
So I extended the sill, and it looks like the lines are denoting some slight curves, so I copied them down to extend it, hoping it would look the same, but its see through.

Do you want it to be curved or straight with a slope?

The reason it’s see through is because you’re missing faces and the faces are missing because the edges aren’t coplanar.

Does coplanar mean the ends of the dotted lines are not connected properly at their ends?

I wanted it to be a continuation of the slope yes

Would i need to redraw the arc so it connected with the dotted line ends?

Coplanar means that all four edges of each rectangle have to lie on the same plane. Basic geometry stuff.

Straight slope or curve? At this point the easiest thing would be to redraw that part of the sill.

Oh yes, I see. I have drawn a rectangle over one portion of the slope and one corner isn’t matching up. Does the dotted line mean its a hidden curve?

The dotted lines mean those edges are hidden or softened.

I would cut it off back at the window frame and redraw it the way you want it to look. It’s not worth the time and effort to repair it.
