I have not yet investigated on how the arcs are draw nor how they are beeing stretched. For the moment I have given up on the algebraic solution but will do some more investigations even if it is fruitless. It would be good if someone could tell me how the arc parameters are created and how they are used. For the moment I have not found a way to stretch them and if the rule is to use data in the .pcb file as true source even if the limiting angles are wrong for the (unknown how the have been created) stretched arc one need to understand the interpretation of the attributes DJ's stretched arc example had different height,width in the file but a ctrl+R did not reflect this. > _______________________________________________ > geda-user mailing list > geda-user@moria.seul.org > http://www.seul.org/cgi-bin/mailman/listinfo/geda-user > _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
