SDS! Bom galera, venho pedir ajuda na alteração de uma IDE que estou realizando agora, vou explica-la por cima e talvez entendam meu problema: O software é um conversor de arquivos .dxf para arquivos .src, ele reconheçe valores de x,y e z das coordenadas do desenho feito no cad e transformarpara linguagem de maquina, de maneira simples e eficaz, meu problema é o seguinte: - Não consigo diferenciar arco de circulo!
