Placing points relative to others

Postby luggw1 » Mon Oct 15, 2012 12:37 am

This may be a difficult question to get across, but I'm going to try just the same. Understand that I come from the background of Bentley Microstation, so it colors the capabilities that I'm looking for in QCad. What I'm looking to be able to do is snap to a point, say an intersection of two lines, and then specify a relative distance from that point to place the first point of a new entity. Is this possible in QCad? I understand that I could create a temporary entity, like a line, to work from, but I've found that sometimes that can get a little messy if the construction lines get away from you.

Thanks.

This can be done in QCAD using relative coordinates.

There is a snap tool that lets you specify a relative coordinate in the tool bat at the top. Relative coordinates relate to the last used point in the drawing, marked with a small red cross and a circle.

You can also enter relative coordinates in the command line using the syntax @x,y, for example:
@10,0
for the point that is 10 units to the right of the last used point.

Other coordinate types are:

Absolute coordinate:
x,y

Absolute polar coordinate:
distance<angle

Relative polar coordinate:
@distance<angle

Thanks, I think that's exactly what I'm looking for. I'll have to play with it to better understand how it works.
