Details

This can be done as is in QCAD today, but a quick convenience UI bit would be much appreciated.

Suppose you are working off a bitmap image (transcribing old scan, or you got your apartment’s floor plan like this, because, uh, what tenant needs DXF). It has dimensions markers and everything, but fat chance it’ll be to actual CAD scale after importing.

So, to bring it to scale, you measure between two tick marks on the scale, compute ratio based on measurement and what’s written on the dimension line, and do a scale operation (you can also have QCAD compute the ratio by using math expression, whatever).

That works fine.

A purely just for convenience function to do that would be much appreciated: pick two points, enter what the actual distance between them is, poof bam, appropriate scaling operation is applied.

As a twist, there could be some other bitmap skewing options, like “the points I’ve selected are on a horizontal/vertical line/at an angle of X degrees, then the bitmap would also be applied this transform.

This task depends upon
