How to avoid 0º in polarang

[jordigort]

Hi all. I am new in the group and I'm not English speaker, so excuse me if I don't make me understand well enough.
I'm building an AutoLISP routine that will allow the drawing in different kinds of perspectives such as calleri din5 ... in a similar way as it is done from the perspective isometric autocad. I can get the axis directions with the system variables polaraddang and polarang. The problem I have is that I can not avoid the angle of 0 °. At any rate I always have a scanning angle of 0 °.
Is there anyone who can help me how to avoid this value?




thanks for your help

here's some code.
once you call de new command da you can draw lines in all the polar anle defined and also in 0º, which, in this context, is only a nuisance.
