Thumbnails of drawing sheets in sheet library
Problem
I am using Vertex BD 2025 (31.0). I have created a drawing sheet library of my own. Some of the sheets do not have a thumbnail image or the image is not up-to-date. How can I update the thumbnail images?
Solution
Run the custom update function. Select System | Update Custom.

Select 30.0 in the Previous update field, and click OK. You will get a list of sheets that have thumbnails added.
