![PANEL](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/1/11655916a47d06def71af4e9bf789bf27d937c8a.jpeg) Hello, I’m a bit new to Dynamo and I’m experimenting with divided surfaces. I’m attempting to achieve the correct dimensions with U = 8 and V = 4. I want a panel with a height of 8’ and a width of 4’. However, I must be making a mistake in Dynamo because I’m not getting the desired sizes. Can anyone help me? ---

Typically U and V are actually the number of panels to place across a face, not the dimensions. You will need to assess the length of the surface edges (using the Isocurves node) and then determine how many U/V divisions they require to get to those dimensions by dividing/rounding. ---

thank you for replying to my forum GavinCrump But, how can I determine the number of panels to place across a face, considering that U and V typically represent the divisions and not the dimensions? Additionally, what is the process for assessing the length of surface edges using the Isocurves node and determining the U/V divisions needed to achieve specific dimensions through division and rounding? ---

Watch my video here from 8 minutes through to 20. I moreorless do what you’re trying to achieve: [![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/a/2ad5953e6b31ca51309e3090e2c7852ec89f37cb.jpeg "Sun hour analysis using Dynamo and Revit (no Ladybug)!") ](https://www.youtube.com/watch?v=9Xu8i809EFE) ---

Thank you immensely for your assistance. I’ve only just realized that you are one of my favorite YouTubers - your videos have been extraordinarily helpful. Additionally, I have an inquiry: I am in search of a Dynamo package that features a red or green light on nodes to signify whether they are operating correctly or obtaining accurate information. Would you know of the specific package I am referencing? also thank you again, its pretty cool that your helping me. ---

Glad to help! Not familiar with that specific package, although the Tuneup extension should generally be helpful for tracking script performance.
