Grid showing not correctly?

Hi, All!

I found that the QCAD grid drawing has some problem.

Steps, set drawing's grid to 150mm.
using snap to grid to measure the distance between two grid points vertically or horizontally, will find that it's not 150mm but 225mm, and zoomout the drawing, will find that it's actually not snapping to correct position.
But when I set grid to 100mm, it's correct. Is this a bug? or just some special behavior?

My QCAD version is 3.21.3.0

Hi,

unfortunately I can't reproduce that.
You are sure that the Grid Snap (SG) was activated and not only GR which makes the Grid only visible.

If the issue still exist please attache the drawing to the post. Thanks

Hi, Husky

I confirmed that I use grid snapping. Please check attached drawing.

Thanks but I have still no problems to snap to the 150 mm grid.

BTW: Your Meta Grid Spacing has funny values - maybe Auto works for you too.

I think you've zoom out to do the snap grid?

Please use my sample DWG, use autozoom first and then try snap grid?

In my case, when setting grid distance to 100mm, the distance is correct. but 150mm, no.

Yep - I can confirm the behavior now.

Please check the Application Preferences for "Automatically scale grid". If that is ticked please untick it and try again. Thanks.
