vassen Posted January 15, 2020 Share Posted January 15, 2020 Hello everyone... 1st point Is there a way to cut a roof generated by vectorworks like we can do in Slab? I want only some part of the roof? Or do i have to create the surface with the extruded surface. 2nd point Can we insert symbol in an extruded surface like we do in wall with windows?

Pat Stanford Posted January 15, 2020 Share Posted January 15, 2020 You should be able to just draw a 2D object (poly, retangle, oval, circle, etc.) select the object and the Roof and do Clip Surface (or Add Surface) to make changes to a Roof or Roof Face. VW does not allow you to insert symbols in anything other than Walls and Roofs. Quote Link to comment

Pat Stanford Posted January 16, 2020 Share Posted January 16, 2020 I created a roof. Drew the rectangle on the right. Selected the roof and the rectangle and did Clip Surface from the Modify menu. I then did the same on the left. I then ungrouped to get Roof Faces and did the same with the circle on the top. And then I Add Surface with an oval at the bottom. I don't know what is up with your roof. Can you try a simple roof in a blank file like I did? Quote Link to comment
vassen Posted January 16, 2020 Author Share Posted January 16, 2020 (edited) @Pat Stanford Thanks. This one work perfectly. Example, if i have a roof of Height 800. If i want to cut at the height of the roof at 455 then will add another roof on top to get the right slope am looking for, are we able to do that? There are two type of slope in my roof. Attach you will see that i want to do with the roof. In the attached images only the orange part was generated automatically. The roof below is just a simple rectangle drawn at the slope angle i wanted. Edited January 16, 2020 by vassen Quote Link to comment
Pat Stanford Posted January 16, 2020 Share Posted January 16, 2020 I don't do a lot with roofs, but I think you can do this. Make a roof that is VERRY tall using the slope of the vertical portions of the roof. Draw a clipping polygon that matches the outside of that roof at the desired height. Select roof and poly and do Clip Surface. You should now have a Roof with a whole in the middle the shape of the clipping polygon. Use the clipping polygon to create a second roof to fill the hole. It will take some trial and error, but I think it will work. 1 Quote Link to comment
Art V Posted January 16, 2020 Share Posted January 16, 2020 Another option to get the same as @Pat Stanford described could be to first generate the roof part with a sloped extruded to the desired height. Then extract the top face to create the polygon for the 2nd roof part extrude with a different slope. Then add both volumes to create a single volume and then shell solid to create the roof thickness you want and have the inner part hollow. Quote Link to comment

Hans-Olav Posted January 17, 2020 Share Posted January 17, 2020 Hi I find it usually easier to use roof faces. Here you have a quick example with two roof faces stacked on top of each other roof test.vwx 1 1 Quote Link to comment
vassen Posted January 17, 2020 Author Share Posted January 17, 2020 @Hans-Olav Thanks for the attachment. Would it be possible to help me to know how you perform it please? Quote Link to comment
Pat Stanford Posted January 19, 2020 Share Posted January 19, 2020 It works for me. In the attached movie I cheated. I have already created the inner polygon that hits the outside of the roof at approximately 15 feet. I created that poly by drawing a couple of large rectangles, One for the main building and one for the bump out. I moved them up 15-feet and then in Left/Right/Front/Back mode I adjusted the edges to match the outside surface of the roof. Here are the basic steps I did. 1. Created the two polygons. 2. Selected the outside polygon and Create Roof with a slope of 80°. 3. Switch to Top/Plan View. 4. Send the Roof to the Back. 5. Select the Roof and the inner Polygon. 6. Clip Surface. 7. With the inner polygon still Selected I Create Roof with s slope of 15°. 8. Switch to Left Isometric View 9. Add Texture to both roofs and render in OpenGL. Note the inside of the lower roof is incorrect. I can't find a way to keep it a roof and have a horizontal cut at the top. So there is a vertical cut on the inside that removes too much until it exits the thickness of the roof. For an external model this is not too bad. If you really need the model correct you will probably have to use the Split tool and deal with the lower section not being a roof but rather a CGS Solid.

Hans-Olav Posted January 23, 2020 Share Posted January 23, 2020 @vassen Sorry I hadn't time to answer and Pat had an excellent solution. I just want to point out that the mirror tool and combine tool is working well with roof faces. I usually build my roofs with roof faces, adjust the first one to my likings and option-drag to duplicate. roof.mov 1 Quote Link to comment
jmhanby Posted November 30, 2022 Share Posted November 30, 2022 I am trying to cut a roof. I ungrouped the roof so my hatch pattern would show. When trying to cut the roof face, it won't cut. So I grouped the faces back together, then I get an "Illegal object(s) selected." error. What am I doing wrong? Quote Link to comment
Benson Shaw Posted December 1, 2022 Share Posted December 1, 2022 (edited) Not sure if this is issue, but the cutting operation (clip surface) should be performed in Top/Plan. -B Edited December 1, 2022 by Benson Shaw Can't leave it alone Quote Link to comment

You can't use the Clip Surface command on a Group. And you shouldn't need to Ungroup your Roof or Roof Face to have it display a Hatch in Top/Plan. You can either apply the Hatch via the Roof container class or if the Roof is Unstyled you can apply the Hatch via the Attributes Palette on an object by object basis. Quote Link to comment
jmhanby Posted December 1, 2022 Share Posted December 1, 2022 (edited) So I redid the roof and was able to cut the rectangle on the left. When I don't ungroup the roof the pattern shows all over the roof and I only want the pattern on top so I ungroup the roof for the pattern only shows on the top. This turns the 4 sides into roof faces. When I try to clip the roof faces on the rectangle in the middle, it clips the rectangle and not the roof. I am in top/plan view. Edit: I just reshaped the roof faces to get the clip I needed. Edited December 1, 2022 by jmhanby Quote Link to comment
