Suggestion: isometric grid

Hi all!

I've been using QCad Community Edition for some months and I found it quite useful for 2D drawing, even handier than the program we use in class, AutoCAD LT 2000 (for example, when splitting an object in two only indicating two points). I'd really like to keep using it (although I have now passed to LibreCAD, which is more modern), but there is no way to use an isometrical grid to do my next drawings. I could do them manually indeed (just drawing lots of lines), but that procedure make easy objects really hard and tedious to draw.

Could you please tell me what do you think about my suggestion! I like your program very much - I hope I can use it as much as I'm able to in the future. :D

This is a great feature request!

it will take some time to implement though. please file a feature request with as more details as possible at our tracker,

Thank!

When you said it would take some time to implement, I was expectings months, not days! I've just downloaded today's Debian build and the isometric grid works perfectly for now.

I just wanted to reply to say: Thank you very much and keep up the great job!

See you!

Wow, great job Dongxu!

@Xavi: Where did you get the Debian build from?

Actually, by implementing this feature, I fixed the algorithm of the snap to grid points function. The old algorithm searches all grid points to find the closest, i.e., O(N) complexity, or O(N^2) in grid spacing.

Now, we simply calculate the closest grid point directly, i.e., O(1) complexity.

Again, thanks for reporting!

There's a repository with daily Debian builds in this link:

See you!

Thanks - those were built against Ubuntu libraries, I haven't tried it
on a debian system and am happy to hear that they worked! Sometimes
Ubuntu bumps the package version of a library which is binary
compatible with a Debian one, but the packaging system doesn't know
that and prevents installation.
