Because I am unable to open your drawing over here ...
Could you attach a screen capture of how your file is displayed in the QCAD GUI.
When failing QCAD does not add the file to the files to open on startup.
Forced that in the config file.
I can now start QCAD in GUI mode from the OS command line with:
"C:\Program Files\QCAD\qcad.exe" 2> "C:[Undisclosed]\error.log"
That creates the content of the error.log file below before it crashes.
It issues 5631 warnings to begin with, many are similar as what is presented in an
earlier post.
The first warning is seen often ... Would not know what the default EUDC font
EUDC.TTE stands for.
A summary:
- link #F is undefined! ... ?!
- cannot assign original handle to object -> collision with object of type: X
- dynamic block ref ... These are not supported by QCAD
- hatch pattern too dense ... 36x
- Boundary loop not closed ... 118x ... The reported gaps are definitely much larger as some accuracy issue
- arc or line not connected to polyline ... 4503x ... Importing data on opening and here not with the nan-nan
RVectors
- Pattern not of even length for QPen ... 948x
Too dense Hatch patterns are often seen as an attempt to fill the boundary(ies) with many pattern lines so that it resembles a solid filled area.
In that case use a Solid fill instead of a pattern.
Also set the Hatch timeout to moderate or low otherwise QCAD will attempt to render every of these Hatches for a longer period.
Generating a vast amount of pattern line segments, flooding the memory.
But the main issues are not closed Boundary loops, the not connecting polyline segments.
And
QPen expects a length of a gap after each length of a visible stroke.
May I ask what the source application is that generated the file in R15(2000) format?
I think that the main issue sits there.
