@Dave R - Thanks for the additional info. That explains a lot. The 3DS model came from my sister's copy of HGTV Home Design Suite. I exported the drawing from there into a 3DS file, then imported that into SU. I thought that would work great, but apparently, something got munged either during the export or import. Or the exporter/importer doesn't work so well.

Well, hopefully not all is lost. I also exported DXF files, so maybe I can use them to build the house. And if that doesn't work, well... then I get to re-create the whole bloody thing manually.

Thanks for the advice, guys.

Thanks for the reply and info, pilou.

I think you are right that the entire model is in a group. When I click any item, the entire model is selected. When I double-click (as you recommended), I'm now able to push/pull the wall, which is some progress. However, I'm still unable to drill holes through the walls. I still get the weird effect where the shape (like a door) pokes out one side of the other of the wall, but there's no hole.

I'm attaching a copy of the model in case you or someone else can take a loot at it and maybe make some sense of it. All I want to do is be able to put doorways through the walls. Sorry the embedded pics didn't show up earlier, but you should be able to see for yourself now what I'm seeing.

Thanks again!

Hi all,

I'm a relative SU newbie, and I just imported a .3DS file of a house. I discovered that the push/pull tool won't work on any of the walls. The push/pull icon has a little red international "no" symbol next to it.

Why can I not push or pull any of the walls? If I draw a shape on a wall, like a circle, I can push/pull it, but it doesn't make a hole through the wall like it would in a shape I drew in SU.

Obviously, there's something about the imported walls that SU is treating differently, but I'm not sure how to fix it. Any ideas?

Thanks!
