i was trying to measure the distance between two nodes on imported mesh, where i don't have geometry, but i couldn't measure, can you please tell me the procedure to measure the distance in the absence of geometry.
You should be able to pick nodes directly in the measure command. Check the following:
1) Nodes are visible. Use show/hide to toggle all entities off then on 2) No selection filter is set when you are in the measure command 3) Selection scope is set to "Entire Assembly" 4) Snap Points are enabled in the Selection bar and "Existing Point" is toggled on
