Why does my curve have angles?

alex_slattery

Hey all I am trying to make a 2 inch line with an arc radius of 8 inches. When I make it I get a choppy looking line with 2 sharp angles. How do I raise the angle count or resolution of the line so it actually looks like a curve and not 3 lines connected together?

Thanks!

Alex, 

Can you post an image of your sketch? Are you using the 'Arc' tool to make the line?

@alex_slattery - You are describing a corner case for graphics.
Rest assured that your model is accurate to 16 decimal places. We facetize all faces based on a chordal and angular deviation.
We have been through many algorithms to get where we are and it is a huge improvement over where we started AND will continue to get better.
One thing we learned early on is that sketch entities should match the underlying geometry and so we use the same facetizing algorithms (facetizing is a constant trade off between aesthetics and speed). That is why arcs with large radii appear to be made up of line segments (they are not).
Please submit an enhancement request so that we can prioritize the work we do each day.

Thanks for the answer! Philip, that makes sense to me. So what you are saying is the preview would render too slow if it had more angles? Please see the pictures below and let me know if I am doing something wrong. Yes, I used the arc tool.
