Wall Points

[Anonymous]

Hello.

I am creating a custom wall label.

I know how to find the wall_position and the end point (with the usage of trigonometry, wall_length & wall_direction) but how can i find the coordinates of the marked points in the attached file?

Looks like you need WALL_THICKNESS as well with a bit more trig.

Hello Barry.

It really depends from the reference lines. If you mirror the left vertical wall then the wall_thickeness will not help to find the inner-corners coordinates.

If the wall_position (starting point) and wall_direction stay the same when you mirror a wall then you need something that will tell you which side the reference line is on (inside/outside) or whether the wall has been flipped on the reference line.
I don't see anything it the GDL manual that can tell you this.

This might be a good question to ask in the forum at GDG Center.

Graphisoft seem to pay a little more attention to questions there.
