FS#1800 - circle/arc intersection bug with line
There is a case that qcad do not detect intersection between a circle/arc and a line. Attached is an example.
qcad-intersection-bug.dxf
(98.8 KiB)
The line is not on Z level 0, but slightly off 0 (3D) which means there is no intersection with the arc on Z level 0.
It is not clear to me, why QCad might change the Z level while the whole drawing is a 2D one. I cannot see in the software that we can embed any 3D (Z) coordinates for any element. How I can solve this problem ?
Those coordinates come from the DXF file.
Edit > Application Preferences > Widgets > Property Editor > Show Z coordinates
Note that Z is shown as 0 as it's extremely close to 0.
Change Z to something else (e.g. 5)
Change Z back to 0
Thank you for the information. But it is still a bug. I start the drawing on QCad, why it changes the Z coordinates. and it makes the design process more complicated if the intersection detection is needed with a part of a block, which will make me explode the block and re-set the Z coordinates by hand. The Z coordinates should not change as the whole drawing is 2D. Can we have facility to reset all z coordinates to 0 in a drawing ?
