Changing Tool Icons

Thursday, January 13th, 2011

One of the little known features of the Punch!CAD products is the ability for the user to change the tool icons. Below are a list of some of the interesting changes you can do regarding the tool icons.


Object Display Resolution

Tuesday, January 4th, 2011

I’m occasionally asked by new users why some smooth objects appear to have straight edges. For example, if they zoom in on a circle they may see a collection of straight line segments making up the circle. This is because internally the circle is represented as a collection of line segments for the purpose of display. In our CAD applications, all objects are displayed as vectors or facets through hardware accelerated OpenGL drivers. Note this is only for display purposes. Everywhere else the exact equation of a circle is used such as in trimming, breaking, or LogiCursor references.
