hi Thanks. I agree that it's quite tricky to get there. Anyway, there is another "riddle" I can't solve. I need to get the 2 roof ridges of a trapezoidal dormer perpendicular to the fascia. I can't seem to find the geometrical - mathematical way to construct this. See attachment and vwx. May you have an idea? It must have something to do with roof slopes and intersections between related faces... Trapezoidal Dormer test.vwx

Hi! Thanks for that. It works, but the consequence of this action is, that the roof gets split up to roof faces this way. We'll lose the benefits of the roof... I have to see if I can live with that. But thanks again, your suggestion was helpful.

Hello Is it possible to make a hole in a roof smaller again or to close it completely? It was previously punched out with "Delete/cut surface"... Haven't found a way to do this yet... Thanks for an input. MiD

Hi there I'm also owner of a Space Mouse - 3dconnexion. The model is from 2016 or 2017. I didn't really use it until now, though. Do you know, if I can still work with it in VW 2021? Is there a kind of usage instructions for 3d-Mouse in VW? I don't know how to install it, and how to implement it. Thanks Michael

ok, thanks for the specification. I'll have a closer look at that point, too. In the end, this has been the problem of the dormer. The next question is, how to solve the joints between dormer and main roof...? Let's see...

Thanks for your suggestions. I'll follow them. That's what I've found out: Intersection between roofs, when one of them has incline in 2 directions doesn't work. (example 1° and 5°).

I'm trying hard to get it right. In the document attached I have 2 examples: 1) 2 roof faces which I got from a roof, that I've changed into faces. 2) 2 roof faces built from scratch. It's strange to me: When I try to edit roof style, the ones built from scratch and aren't possible to offset, do not show "edit roof style" when I right click on them. While the other 2 do. (They have been extracted from a former roof.) Can it be that there is a different behavior when roof faces are "exploded" roofs? Roof faces 2.vwx

Thanks for your help, @Hans-Olav Please, could you try joining the 2 roof faces in the document attached. I can't seem to get there... They should make up a trapezoidal dormer in the end. Roof faces.vwx

ok. I think I got it. Thanks. this works. unfortunately, a roof face like this doesn't properly work in offset with another roof face. 🤪 It's quite a lot of effort to build something as common as a trapezoidal dormer, don't you agree?

Hi Hans-Olav. Thanks for reply. It's not possible to rotate a roof face in 3d > see attachment. It says "Hybrid objects can only be rotated around z-axis. I've tried to rotate a simple rectangle in x and y, and then make a roof face out of it. Even that is not possible... It's quite disappointing, that such an advanced software can't solve such a common task...

Thanks for your suggestion. The problem is : I have one face with 65°. Slab isn't possible with such incline...

Hi Does anybody know I can create a roof face with incline in both directions (X and Y)? Thanks for help. Mi&D

@Tom W. At least I got closer to solve it. In my example of trapezoidal Dormer I succeeded in joining 2x2 roof faces. (It hasn't been possible to join a pair 2-layered roof faces). Still, I have some issues at the offset. There is one edge that shouldn't be there. And the at the inner intersection lines do not meet in the same point... Is this the best we can get? PS. In the thread I've found your statement: "to join two Roof Faces using Dual Object Connect Mode + Mitre Roof Face Joins Mode". I am using a Swiss version of VW. Could you please show me the icons of these 2 Modes. I might need to check... On the other hand, you're mentioning, that the horizontal face should be set at 0.1° (trick). Unfortunately, in my case I can't rotate the 8° (y-axis) face 0.1° in the other direction (x-axis)... Do you know a way how to incline the roof face in both directions (0.1° and 8°)? This would solve the problem I guess.

Thanks @Tom W. You guys rock! In our European Forum we don't get that far in analyzing tools and looking for solutions. Great effort! I'll have to study this.

@Tom W. I did some research meanwhile concerning roof faces offset: - 2 faces with equal angle : offset is ok - 2 faces with different angle: offset with troubles - 1 face is 0° (flat) : offset doesn't work... see screenshots 1,2,3 Am I doing something wrong? Or is it a bug?
