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?
Have you tried to create a new file and then reference that file into it, place a fence around the file and copy it into your current file? then detach that reference.
I have had this problem you refer to above on a few DGN models. All element information disappears along a complex alignment. It only appears when you have zoomed in to a particular level. It happens on some DGNs and not others and is very difficult to reproduce when needed.
I have seen this issue in SS3. Is that where you have seen it? But I have not seen it in SS2. If anyone has a DGN where they can reproduce the issue, I would really like to test with it.
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.
