Interior partitions shrink Sketchup<->OpenStudio
Sometimes interior partition's geometry changes (one or two sides of a rectangle shrink) when going back and forth between Sketchup and OpenStudio.
Is there a question here? If you are reporting a bug or issue, you could do so on the OpenStudio GitHub issues page.
Yep, unless you have an actual question I'll close this one, just letting you have enough time to do so for now.
Do you mean that when you open an OSM in the OpenStudio SketchUp plugin, the vertices of surfaces may change? This can happen if SketchUp's algorithms correct the surface vertices slightly. However, I would not expect that surface vertices would continue to change if you open an OSM in the SketchUp plug-in, save it, and re-open.
Opening an OSM in the OpenStudio Application should not change the vertices at all.
I didn't want to report this as a bug right away and so I thought I'd present it to the community at first to see if there was a common mis-step that caused this. What I may have done is I resized the partition just by selecting/resizing it as an object in the space, instead of double-clicking into the partition group and resizing the surface itself. Can't remember if I did this. But, I do know that when I saved it at least looked resized.
You have to be careful using some of the SketchUp tools (like scale tool). They will look like they work, but when you re-open your OSM file you will see that the changes were not recognized. Also, you know to only save and open the OSM file right? In the general OpenStudio workflow the SKP file does not need to be saved.
