Can't edit length of interior elevation section-elevation line in Troubleshooting Posted October 3, 2020 @sara.t Welcome to the Forum! Which version of Vectorworks and Service Pack (SP) are you currently using? You can find this under the Vectorworks menu > About Vectorworks. In the lower left of that same About Vectorworks window, it is a good idea to press "Check for Updates" to see if there is a newer SP you should be using. If you need to update, please do then re-check to see if the issue persists. (It also helps to add your computer specs and Vectorworks version info to your Community Forum signature. You can do this via the icon in the upper right corner > Account Settings > Signature.) If you are up-to-date with your SPs for the Vectorworks version you are running, try saving and closing the file, and re-opening it. It that doesn't solve it, trying quitting Vectorworks and restarting it, then checking again. If that doesn't solve it, try restarting your computer and checking again. About the interior elevation extents, as I check the same thing in VW2021 SP0 (the initial release), I'm not seeing the same blue handles you are (which made me wonder about the Vectorworks version and SP you are using). Below is an image of what I get. As expected, I am able to change the length of the interior elevation using the two handles that I have highlighted. Please check back in here with your Vectorworks version and we can go from there. This may be something that our tech support team should look at with you but a simple SP update may take care of it.
