Hey there!
I am attempting to create a Python automation script that reconstructs a series of meshes using the makeSolid tool set to a certain cell size. I have a script I have used before to remesh objects and was going to update that. Basically, I want to open a mesh and use the makeSolid tool in Fast mode with the cell size set to 2.5mm. However, when I look at the mm-api documentation python_html (GitHub version linked here), I don't see all the parameters I think I need.
I can see I would want to set solidType to 1 for Fast Mode (with closeHoles = T and transferFaceGroups = F, which I presume are the defaults). But it seems that with solidResolution and meshResolution both taking integers, these are referring to the Solid Accuracy and Mesh Density sliders in MM. So does that mean it is impossible to set the cell size through python scripting?
I notice that when you type in a certain cell size in MM itself, it basically calculates the integers for Solid Accuracy and Mesh Density that would give you the closest value to the desired cell size. Perhaps is there a way to calculate what these values would be and then I could set my values to those?
At the moment, here is the basic code I have and I would be super keen to hear any and all ideas!
