Instead of a circle i get polygon
Hello
I have a problem with creo parametric 2. I cant make a circle if i use very small dimnsions. Instead of a circle or a hole i get polygon.
Every program to generate computer graphics makes use of approximation to keep speed.
This is managed in two ways in Creo.
One is static and is user managed by part accuracy. This sets how closely the evaluation of geometry matches the ideal geometry. Smaller accuracy values are used to get better results in smaller features. It can either be absolute accuracy or relative accuracy. Relative accuracy scales the accuracy as a ratio to overall part size. Absolute accuracy does notscale with part size and should be used if the ratio of smallest to largest features is large.
The other is dynamic and is automatically applied to the on-screen appearance. It scales the appearance relative to the zoom level and doesn't affect geometry calculations, leaving small features looking rough. To change this, zoom in and then regenerate the model. This will re-evaluate the graphics appearance.
You will find that a point placed on the edge of the hole will follow the more precise edge of the hole and ignore any apparent polygon.
