Another one for the well-under-4KB* series...
The length of the object is the length of the long line. The length of the short line is set by the Short Line Factor parameter. You can adjust this factor graphically. The spacing of the lines is controlled by the Spacing parameter. Also graphi-justable.
This is a good one to place with the rotate and stretch geometry method (fourth button). With this method I had an intermittent glitchy behavior where the object would appear offset from my clicks, but I couldn't reproduce it.
I wanted to add this symbol to our doors and windows directly, but I don't think it's possible to force the lines to tilt rightward in every case, once you factor in the orientation of the door and the viewpoint and all that.
