Hi

i can not remake the error


when i redefine A a dependent point A=mirror[B,O] is created but if i type A=mirror[B,O] in input line a free point in mirror[B,O] is created


is it possible Piman has more objects producing the error?


saludos

Hi Mathmagic, Noel


See this file and tries to redefine A as Mirror[B,O] :

Hi Noel


I already did several attempts to establish a line in the Poincaré disk and create the respetive tool. But I always encounter some problem.. I believe that there is any problem with the object circle and / or with their centre ...

Indeed, in several attempts I made to create such a tool, I met several times the following error message: Point O (centre of the circle) is not defined ...

Hi Piman try this:

open teste_redefine

view->construction protocol


then order the objects

1->c

2->O

3->B

4->A


then redefine
