The following issue was submitted to Bentley Technical Support. This issue has been transferred to this forum so that the community can benefit from the troubleshooting techniques and resolution.
As soon as I open DGN files after a specific person in our office worked on it, the line elements disappear when zooming in. For example, when you have a line and you zoom in, after a certain distance the line disappears. When you zoom back out, after a certain distance, the line reappears.
I tried the following solutions neither of them worked (these solutions were found on Be Communities):
• Another simple trick to fix elements with incorrect range issues is to force microstation to rotate everything by 0 degrees. Using a very small fence with nothing in it, then rotating all elements by 0 degrees will have no visible effect, but will cause microstation to re-evaluate each element's range, and should reset it.
Place a fence (use a very small fence with no elements in it)Rotate method: active angle > set to 0 degrees...About element center: doesn't matter if it is checked or not since degrees is 0 copies: uncheckedUse fence: checked and set to void-overlap
• You mentioned that this happens to "some" colleagues. If this behavior does not happen to the same file on some computers, you may have a video card/driver issue. I've seen similar behavior in the past, and one solution was to go to the Troubleshoot tab on the Advanced Settings of the display properties and move the hardware acceleration slider back a couple of notches.
If you could answer a couple of questions, I will be able to better troubleshoot this issue.
Would it be possible for you to attach a problem DGN file to this thread for testing purposes?
Answers to your questions:
We are both working on Power Civil V8i for South Africa_SS2; 08.11.07.566.
Attached is the drawing as requested; I have circled the once that have the zoom issue.
To resolve this issue, please create a new file from seed. Reference in the DGN that is having the issue. Then merge the reference into the new seed file.
I just tried this on the test file, and the issue was resolved.
Without hands-on testing, it's impossible to determine what particular action from the other user is causing this problem.
I created a new dgn, using the bentley 3d seed file and then merged as you said - the issue still persists, I tried copying the attachment instead of merging but the elements still disappear when I zoom in. We found a solution by exporting the file as a 2D, then only does the problem get resolved.
Have you tried to change the display depth?
MicroStation key-in "dp=-5000, 5000".
thank you so much for your reply, i tried it and it worked! Very happy that we found a solution to this saves me lots of time having to create 2D drawings.
