Summary0003697: Opening huge 147 MB STEP file leads to "Not responding"
DescriptionI am not a regular user of FreeCAD, I only just installed it before trying to do this and seeing this problem.

I am only trying to use FreeCAD to convert a complete STEP model of the Ultimaker 3 Extended, into a mesh for use in non-CAD 3D modeling software.

The problem is not that FreeCAD has crashed but that it is working so hard on reading the STEP file, that it stops responding to Windows, which to the end user may appear to be a crash or freeze.

FreeCAD needs to:
[list]
[*]Be modified to display a progress bar during a long import or file-open task that takes more than a few seconds,
[*]Actively update the progress bar as the import/open task runs, optionally with a Cancel button to allow aborting of an unexpectedly long import/open task,
[*]Respond to Windows during the import so that the system doesn't display Not Responding.
[/list]
Steps To ReproduceThis is all I have done with FreeCAD, so far:
[list=1]
[*]Install FreeCAD-0.17.13541.9948ee4-WIN-x64-installer.exe
[*]Go to https://github.com/Ultimaker/Ultimaker3Extended
[*]Click Clone or Download, then Download ZIP. Extract ZIP
[*]Inside is a folder named "3D model Ultimaker 3 extended", which contains a second "9511.STEP.zip". Extract.
[*]Open the 147 megabyte "9511.STEP" with OpenCAD
[*]After a short period an hourglass will appear, and if the Windows Task Manager is opened it says OpenCAD is Not Responding.
[*]Eventually after about 10 minutes of waiting through this with no feedback from the program, it will open with no error.
