SharonP Posted February 17, 2020 Share Posted February 17, 2020 I have a very straightforward roof for a small house, which I created as a roof, then ungrouped so I could alter one roof face. I have done this many times before with no issues. This time however, I can only see the roof in 2D view, and as soon as I try to look at it in any 3D view it disappears - I can select the roof faces before changing the view and the OIP will say I have 7 roof faces selected, I just can't see any of them. I have tried fit to objects in case the roof faces are in a funny place, but still nothing shows up. Classes are all visible. Any clues? Sharon Quote Link to comment
cberg Posted February 17, 2020 Share Posted February 17, 2020 Is the model very far away from the drawing origin? Check to see if the numbers in the ruler thing are very large.... Quote Link to comment
SharonP Posted February 17, 2020 Author Share Posted February 17, 2020 Nope, very close to origin - numbers are between 0-20000, so almost centred on origin. Quote Link to comment
cberg Posted February 17, 2020 Share Posted February 17, 2020 (edited) Try double clicking into the roof face to see if there is stray geometry. Sometimes there can be lines or duplicate geometry that can make 2d representation a problem. I double click and cut the geometry I want to keep. Then select all and delete whatever is leftover. Then paste the good geometry back in place. That way you can make sure geometry is clean. Otherwise make sure polygon is closed. Edited February 17, 2020 by cberg Quote Link to comment
SharonP Posted February 17, 2020 Author Share Posted February 17, 2020 ok, I have just checked each roof face, and the only geometry in each one was a single polygon, so no stray bits and pieces there. I have just tried creating a new unedited roof on top of the walls, and it creates fine, I can see it in a 2D plan, it has solid fill visible in a 2D plan. I have it selected, and as soon as I go to a 3D view (in this case I have just tried a Right hand view) it disappears-I can still see the blue squares indicating I have something selected and the OIP says it is my roof. The roof is sitting directly on top of the walls, as indicated by the location of the blue squares. I have never had this happen before.... baffling. Quote Link to comment
cberg Posted February 17, 2020 Share Posted February 17, 2020 Have you copied the roof to a new file to see if works in a clean file? Quote Link to comment
SharonP Posted February 17, 2020 Author Share Posted February 17, 2020 I have just tried that... and it does. Guess I will have to copy everything to a new file. Thanks for the help. Sharon Quote Link to comment
cberg Posted February 17, 2020 Share Posted February 17, 2020 Maybe there is a classes issue going on? Are all your classes turned on? Quote Link to comment
SharonP Posted February 17, 2020 Author Share Posted February 17, 2020 yeah, they are Quote Link to comment
cberg Posted February 17, 2020 Share Posted February 17, 2020 Before giving up on the file, I might try to make a new roof face to see if it solves the problem. Pay special attention to the class of the rectangle that you use to make the roof face. If it's a relatively simple roof face, you should have your polygon and you know all the settings.

mike m oz Posted February 17, 2020 Share Posted February 17, 2020 Try this: - copy the Roof Face object. - paste in place into a new blank file. - copy that pasted Roof Face object. - go back to the original file and delete the Roof Face object. - paste in place the copied Roof Face object. This process makes the Roof Space object regenerate and it may solve the problem you are having. The other thing I would do is check the 2D source geometry of the Roof Face object to ensure that it is closed and doesn't have vertices very close to each other at one of the corners.
