Bad visual behaviour for dimensions lines

Post by louis » Thu Jun 11, 2020 1:33 pm

Hello,

I would like to report a bad behaviour for the dimension lines at the bottom of my DWG file. For example with Autodesk DWG true view the dimension line is more readable.
Do you know if this behaviour is due to the difference between the 2 software ?
Can we change something to have a better readability ?

Thanks

In your DWGTrueView.png dimensions are not rendered.
In the QCAD png they are.
see my answer here:

The file contains definitions for all those dimension entities shown by QCAD.

The way how dimensions work in Autocad is as follows:
- A dimension entity is stored with all its data (coordinates, distances, angles, etc.).
- In addition to the dimension data, a special block is stored that contains the visual representation of the dimension entity (lines, arrows, text, etc.).
- In the file you have attached, these dimension blocks are empty or contain data that is different than what would be expected from a dimension entity.

You can try to imitate the same behavior in QCAD by passing the command line switch -recompute-dim to QCAD.

Yes. We can use 3D software for 3D drawings and 2D software for 2D drawings!

I said it before and I say it again (but for the last time): Your drawing is a 3D drawing and not prepared to be processed in QCAD. Question about "bad behavior" are irrelevant. Fix all Z-Values and see how QCAD then behaves ...
