I don't know what's going on but have noticed a couple things. First, I
loaded the file into librecad and deleted everything except the center of
the 'A' in Accelerometer. This leaves just a single 3-point polyline.
Heekscad still has a problem importing it.
The specific error message is: "OpenCascade failures occured during DXF
read processing"
I created a similar polyline in librecad and it imported fine into
heekscad. When I used LibreCAD to exploded both the corel created and
librecad created polylines, the corel version became many small segments
and the librecad became 3 large segments. Once exploded, both imported
fine.
Exploding the entire original file produces over 22K segments so I don't
recommend it as a solution.

I got the same error message "OpenCascade failures occured during DXF read
processing"
I also tried opening the file with FreeCAD and Inkscape, with no luck.
Draftsight opens it fine. It appears that all the geometry is made up of
splines. Since the import code for HeeksCAD, FreeCAD, and Inkscape are all
missing a way of working with the file, I'm not sure what to do to fix it.

It looks like qcad/librecad will open the file too. Hopefully someone can
help you figure out how to deal with the splines in the dxf.cpp file. Maybe
those working examples will help them.

I tried this with Draftsight:
Print to file in svg format. Then Heekscad seems to open the svg file.
