Question

Surface quality

Hello,

I am creating curves through points. Curves are used to create boundary blend. Before creating points and curves, I have set model accuracy to 0.1.

I would like to enhance surface quality. Any thoughts will be of great help. Thanks in advance.

Regards

Ketan

Do you have the advanced surfacing extension?

Creo is somewhat limited out of the box when it comes to quality surfaces.

Creo is simply too literal to "fudge" a feature.

Do not confuse the graphics quality with the surface quality.

Model accuracy is relevant but it more to do with how accurately it calculates your curve.

When I do involute curve equations, you can see the starting angle change as you change precision/accuracy.

As you lower the accuracy, the more crude your edges become.  Use the analysis comb to determine curvature.

Also, boundary blends are inherently sensitive to the joining surface.

As surfaces cumulate in your design, the edge quality or tangency will be diminished in quality.

This is a long discussion that may have some pearls of wisdom for you:

    Hi,

    Thanks a lot for this.


    As I am doing curve through points with spline option; spline is deciding curve and hence surface quality. I would like to improve min and max curvature radius of surface. How to achieve is a pain area for me now. Any thought on this?


    Thanks and Regards

    You can control curvature and starting angle of a curve in the sketch.  It has a few dependencies but manipulating curves is more than comes up on the menus.

    You can also control the curvature of the boundary blend in the dialog.  Again, not immediately obvious.
