Quit often, as I am drawing duct all of a sudden the duct in the area I am working dissapears. I can go to 3d view, plan view, I can regen, do an objrelupdate, and it will not come back unless I save and close the drawing and re-open it. Has anyone else had this happen?
Thank you for your post. Int his case it could be a number of things but typically is associated with something visual within the software (settings, etc.). One thing to check is your graphics system being used itself and if it is certified for use in the version of software. I have included a link below.
Another area is to toggle the hardware acceleration of the graphics card to see if you notice any difference in overall functionality. This can be toggled within your program and I have included a link below on how to administer this check.

The other area of interest is the cut plane and the display representations themselves. These can play a large part on overall visual appearance within the file. These settings are located in the bottom right of the interface and can be adjusted as needed. I have included a helpful link below with details on Displays in the MEP software.
Please let us know if this helped in this post. Thank you.
