Novice user here. I want to create cross sections of a model that was imported to blender from sketchfab but have been unable to. This problem is very similar to the prior stack exchange question/answer (Create Cross Sections and 2D planes in Blender). The difference here is the model I'm starting with consists of multiple objects.
I think the issue is that the model consists of multiple objects.
In order to join the model into a single object I tried both “control J” and the boolean modifier “union”. While I eventually was able to join all of the objects into one, blender would freeze or give different outputs when attempting to get a cross section of an area that previously consisted of separate parts.
Aside from joining the model into a single object, I also attempted to place a plane that crossed over the model and then applied the boolean modifier “difference” to create a cross section out of the plane. This method was effective when the plan interested a single piece of the model but would then start to give different outputs when intersecting more than one piece.
Here is a link to the Sketchfab model I am trying to create cross sections from : https://sketchfab.com/3d-models/baby-f05a87806cad49feb75ac7659d55c368
Summary: 1.) How do I consolidate the sketchfab model into a single object? 2.) How do I get cross sections from the consolidated model?
