You are very fast with creating a bug report before having approved your first post! And you ignored the really HUGE banner in the bug tracker telling you how to proceed. Before creating your next bug report, please read how to do so: https://forum.freecadweb.org/viewtopic.php?f=3&t=5236 . Discuss here if it is a bug at all (it is not, it's a feature request), check with the most recent version (you did not), check if a previous similar ticket exists (I'm pretty sure it does). Sorry for being that frank, it's a riddle to me how people start learning a new software start with a bug report right away. Now we can discuss your issue described here:
The step file contains several parts each having its own origin. FreeCAD is clever enough not to show them initially. When you say "Show All Objects" FreeCAD does as it is told and shows everything. You should have selected just the top level parts and toggle their visibility with the space bar.
I went into the menus to View - Visibility -> Show All Objects.... and suddenly I get this mess thrown in my face:
Code: Select all
# Hides all objects from active document, if name starts with "Origin" doc = App.ActiveDocument if doc != None: Objects = doc.Objects for object in Objects: if object.Name.startswith(u"Origin"): print ("found:", object.Name) object.ViewObject.Visibility = False print ("Works only with an active document")
As you noted, this is a huge STEP file... hanging in loading is a 'normal' behavior for this kind of files, also in proprietary CAD sw.Dale Mahalko wrote: ↑Sat Nov 17, 2018 5:21 amI just downloaded FreeCAD tonight, to try to convert a STEP into a mesh for other non-CAD 3D editors. I am not at all familiar with FreeCAD, but I have used other CAD before.
The STEP is massive, 147 megabytes, a model of the Ultimaker 3 Extended 3D printer. It can be downloaded here:

When you open it, FreeCAD will apparently hang, says Not Responding. It's not dead, it's just working really really really hard. Find something else to do for about ten minutes or so.
(I filed a bug report, it should show some sort of progress bar and not hang like this in a manner that annoys Windows.)
so the failure is in Sketchup that cannot import STEP natively and not in FreeCAD that can import it just fine.Dale Mahalko wrote: ↑Sat Nov 17, 2018 10:10 amThis project I am trying to do appears to be a failure. I will have to try to find some other program that can convert STEP into other formats.
I got to the point of deleting everything but the outermost visible shells/rods, then tried to export into something Sketchup understands.
This may depend on what you did on your 'refined' model.

This is the mess when we do not place all the components on the same origin (at best a maximum)I get this mess thrown in my face
