Construction only works after moving a point

Lars Rönnbäck shared this question 2 years ago

I have this simple geometrical construction, but the second sector, colored orange, does not show up unless you move the point C a bit first. I cannot see anything wrong with the actual construction, and after moving C and the sector becomes visible, it works as expected.

This is the link to the construction in question:

the problem is the point E

you can try E=intersect(e,g,1)

I ever create two intersect(e,g) points (g as line, not ray) then select the wanted point with If() comand

also you can try uncheck the "allow outlying intersections" properti of g


alternative attached.

Note: for polar notation of points (<length>;<angle>) see also manual
