Note: FreeCAD's support of OpenSCAD text command required use of DXF.
Maybe you do not have the right options for dealing with DXF files.

If I go to preferences and then Import/Export
For DXF I have the following options set

Use legacy DXF importer
Allow FreeCAD to automatically download and update the DXF libraries

DXF library failed to import - had to import by hand DXF library ...
still no text imported even in CSG

but that doesn't help the dysfunctional memory leak.

I can do the same operations in blendercam without the memory leak. Selecting faces doesn't take minutes and large memory chunks there.

I am wondering if I should ditch freecad path because of it. It is obviously not able to deal with any STL model with medium complexity. Great if you want to cut a few holes and a square. Even then, DXF2GCODE would perform for simple cuts.

Hi @palain In that case you have something wrong with your installation. Have you tried FreeCAD 0.17 under Linux?
You should not have to import by hand and it sounds like importing by hand did not work properly

but that doesn't help the dysfunctional memory leak

I assume that means you have some problem with the path workbench.

Given the nature of STL files being just meshes then I am not surprised that the Path workbench
struggles with them

Sorry, don't know anything about the path workbench so cannot help there.
I am just one of the developers of the OpenSCAD workbench. In fact the only one left
as Sebastian Hoogen is no longer around.

If you want to provide me with a test text string I can create a FreeCAD file for you
Or if you let me have a SCAD or CSG file I again can produce a FreeCAD file that you can then use
with the Path workbench and see if that is okay.

I observed the similar phenomenon in Part workbench.
This seems to be the memory leak in FreeCAD.

Without additional information, this post is rather useless. You answered to a post from 2018 and refer to a topic from 2016 and you don't give any further information except that it occurs in Part workbench, while this is the path forum. So what is this about? .

Is it possible to upgrade to 019 Git version .
The PATH WB has several changes regarding Memory Consumption.
I've come across a similar issue where memory went up to 12 Gb.
Closing the model does not release the memory.
Restarting FC does.

In the latest Git release memory use is far less.
