Question

How to change spine curves edges to circular or arc edges

I am working with a model that has a curved body or feature, that looks likes it was created with a resolve. I checked the fastener hole edge curves on both sides of this feature, which is nonplanar. One side of the hole is made up of two split arc edges. The other side of the hole is made up of two spit spline edges. The spine edges is an issue in creating a fastener in Simulate. I tied to use the Round to edit the spines but if this is the correct tool I can’t figure out how to replace the spine edge with arc edges. 

 

Does anyone know the approach to doing this? I only have the Creo Parametric not any advanced design add-on licenses.

It would be very helpful to understand your issues if you could upload your file, or share a sketch to describe what you want to resolve. Thanks

BHOoi, I don’t have a pic at the moment, but the issue is the axis of the fastener is not perpendicular to the surface because the surface is a arc shape or non-planer. So that being said the fastener can’t create since the axis needs to be perpendicular to the surface.

If you just need an axis in this context, then try the following in part mode. To generate the axis needed (normal to surface) at center of the opening, create a copy of the surface and fill the hole using that option in the copy UI. Then you can create a point (if one is not already defined) at the centroid of the opening and an axis through the point that is normal to the surface you just created.
