Hi Andrew, hi Clive,

I use QCAD/CAM in most cases to produce g-code for parts needed to build model airplanes, like p. e. profiles.
In the moment I have to go the way over other programs to draw aerodynamic profiles. Interesing thing would be a possibility to simply import an xy table.
QCAD has so many options, so I wouldn't be astonished if this possibility is already implemented.

Best Regards,

Misc > Import/Export > Import Points imports points from a simple x,y list:

x1,y1
x2,y2
x3,y3
...

However, it might be more convenient to simply paste your x,y list into the QCAD command line input:
viewtopic.php?f=47&t=5579

Thanks a lot for your hint. It's just as I assumed: there exists already possibilities!

Best Regards,
Christof

Hi Andrew,

is there a function to connect two points by line or
convert two points into a line with the points as start- and endpoint of the line?

Hi,

Maybe the attached is similar to the solution you seek. It takes a text input file of x,y pairs and connects adjacent points. I used it to construct an airfoil shape from data someone posted, I think here on the QCAD forum.

Just copy the folder into the scripts folder and you should be good to go. It's set to split the text on commas, but you can change that in the code. Also, it zooms to the points imported, and if there's a bread in the data, it doesn't connect adjacent points.

Sorry, I don't seem to be able to delete what appears to be a duplicate of the image below.

Cheers,
