Hi @mas985 and @jousefm,
I would like to jump in to clarify - we are doing a gradual release of our new CAD handling system. Before there were issues that some CAD files were sized incorrectly, usually 1000x too big. Beginning with the new workflow, we will convert all CAD files to meters on upload.
In your case @mas985, I believe the inches would be converted to the appropriate size in meters during the upload/import to SimScale. To be sure, I'm tagging @jprobst who works directly with the CAD handling on SimScale. He can provide more details in this case.
Regarding your follow up question, the bounding box is currently the only measurement available. Our product road map is shaped by our users to please add all of your requests to improve the experience on SimScale in our Vote for Features category.
In the meantime, I will make a note to update this FAQ as well. Thanks for you input
