Hi,

I find out that going fron a circle in 2D to 3D structure the arc definition is not really good. Do i need to use the Spline tool to rebuild the entire circle or there is another way.

PS: sorry for my english, i am french.

thanks

If you sketched with the circle command in the Sketcher and revolve it, it's a circle, it sounds like you might be seeing display quality? Can you post a picture?

This is due to the conversion from a precise surface definition, which Pro/E maintains, to a faceted representation which the computer graphics card displays. Sometimes just regenerating the model when zoomed up will cause a smoother representation to be made. This will happen even with the spline tool. It doesn't affect the actual smoothness of the surface - a CNC program would make a very smooth curve based on the Pro/E data.

ITS ONLY A GRAPHICS DISPLAY ISSUE,Eric Terrell HAS EXACTLY ANSWERED THIS QUESTION,SETTING EDGE DISPLAY QUALITY TO VERY HIGH AND USING MORE POWERFULL GRAPHICS CARD COULD BE MORE BETTER.
