Thanks a lot

It's pretty simple, but kind of confusing at the same time.

1) Select the roof tool on your Tool box
2) Select the roof you want to cut a hole in
3) Click inside the roof to start drawing the hole inside the roof.

Or in the Arrow tool, click on the edge of the roof and choose the Subtract from Polygon pet pelette option and minus any area you like based on the current geometry selected in the Info Box.

Actually Link's method is probably better since it allows you to draw a hole that extends beyond the original element's shape without getting an error message.

Thanks for the replies...
But i should have said that i want to do it in a polyroof.
In this kind of roof, the subtract options, etc, do not appear...only some.
In the first two types, i have no problem...only in this one. Otherwise i will have to draw it in lines, and then make 6 or 7 different roofs.
Thanks

I'm not sure I understand. Can you post a screen shot?

You probably having grouping enabled. Hit Alt+G (to suspend grouping) and then see what the pet palette offers you. Either way, there is still no way to put holes into multiple roofs at the same time. You need to subtract from each piece of roof individually.

You can make any hole in any roof or group of roofs by SolidElement operations. Build some slab in a form of hole you want to have, plase this slab in the place where your hole must be, in 3d mode deselect all and use SolidElement operations in Edit menu in AC9 and in Design menu in AC10. There are 3 buttons
1. select your rooof, or group, and push ...Target...
2. select your slab, and push ...Opearator...
3....Execute...

Then place your slab in non needable layer and hide this layer in Layer settings.

An SEO will get the hole in the roof alright, but I dare say the lack of floor plan display would probably be the undoing of this method.

Specially to Link...Yup...when you do a polyroof, then if you want to have more options you have to ungroup...now i can do anything i want.
