Hello, I’m replying to an old conversation because this seems to be the same issue. I am trying to work with a drawing that I created in a vector drawing program. I converted it to dxf and imported, but it is extremely slow to do any operations at all. It is a fairly large spline, with several thousand nodes I think, but it’s more or less instantaneous in the 2D drawing program, so I know it’s not excessive.
In Shapr3d on a reasonably new iPad Pro, or also on the beta on a newish Macbook Pro, it takes several minutes just to select the drawing. Things like “translate 20 mm vertically” take a similar amount of time. I extruded it and then tried to intersect, and that took upwards of 10 minutes for the progress animation to finish.
I’m not able to include it as an attachment because I have a new account, but hopefully this link lets you get the file. You should be able to reliably reproduce this issue by:
-Create a new empty Shapr3d document
-Import the dxf file
-Double-tap to select the whole spline, or else tap the folder
-translate 20 mm upwards
That last step takes several minutes, for me.
