Hi, when I'm routing conduit or cable tray in a view other than 2D wireframe and cancel the command all or some of the parts will disappear. The only way i can seem to get them to show up again, other than restarting the program, is to go back into 2D wireframe. Any help would be appreciated.
Thank you for your post. In this case and from what I have seen in the past, this typically would relate to one of the following, the object, display representations, and/or graphics system and settings on the system. One thing that may help or at least worth a quick test would be to take your current problematic file, and then insert into a new clean and blank template file (stock) that has all stock display representations loaded. From here you will then be able to compare overall visuals.
If this does not render a more favorable response from the system, please navigate to the link below and generate a working system information file (NFO) for review. This will help us better understand the system environment and offer further possible solutions to this case. Thank you and we look forward to your reply post.
If all you are doing is changing your Visual Style then it is probably not a display representation problem. Your conduit should not appear/dissapear depending on which visual style you are using. I would check that you are using a certified video card and that it is "Hefty" enough to handle the application. I was also start the 3DCONFIG command and select the Manual Tune button and make sure that you are using 3D acceleration. The Enable Hardware acceleration button should be checked. Sometimes when you install/reinstall Autocad MEP it will turn this off by default.
There isn't any layers isolated to end the isolation command you mentioned. Attached is a better screenshot of the issue. The conduit is the same layer from end to end but some parts are missing in concept view.
Based on the screenshots and your description of the issue I would say that it is related to your video card and other hardware.
