I've imported a DXF file on to my PCB editor in altium designer 18. The problem I have is Altium will not selcet my import. I've tried select All I've run my mouse over the object, some of the object seems to be selected but t he radius's are misssed out. Ive tried putting all the imports on one mechanical layer still doesnt work. This is driving me nuts can anyone help??
Check if you have any kind of selection filter. It seems that you aren't able to select arcs. Clear all filters to make sure you can select all objects.
Anyway, once imported in Alitum, DXF files can miss some information (arcs may be converted into very small segments). It is a quite common issue.
