I occasionally have an issue in Layout - If I pull a dimension between two points on the same horizontal plane, the dimension reads accurately. However, if I try to pull a horizontal dimension using points that are not on the same horizontal plane, the dimension reads as the diagonal distance between the two points no matter how I orient the dimension after initiating it. Attached is a screenshot for reference. This only happens occasionally, and I can’t figure out what setting configuration to change.
Have you tried pulling down or up further on the page?
This is possibly a consequence of the cutting plane not being exactly perpendicular to the treads. I have a feeling there are recent changes in the code that have altered the mathematical accuracy and inference sensitivity. If the dimension sees a distant point first it will latch on to it. I haven’t tried this but if you adjust the camera view in Layout you should see the connection points for the dimensions.
I was caught out by a similar thing a few months back that didn’t relate to the cut plane, the dimension was latching onto a node in a lower one of my stacked views. I now turn off any stacked views prior to dimensioning. Could that be a reason?
