Common practice for creating grids on curved surfaces

Hey community,

 

I have been working to make a cylindrical x-grid type thing, which I did successfully, but I am curious if there is a more efficient way to create curved grids like this, panel isogrids, etc. I flattened a cylinder and added an extruded pattern to it, which wasn't crazy difficult but pattern generation took a decent amount of time. Is there a way to do this using tools that require less computing time, or a common practice like making sections of grids and join them in an assembly? Attached is an image of the model tree and the part.

From your model tree it looks like you are using a standard pattern. I would recommend trying a Geometry Pattern (use the dropdown under Pattern). For large numbers of pattern instances it can be incredibly fast. The slowest part of any feature creation is joining the new geometry to the existing and running the verification that it is all valid geometry. The geometry pattern does a surface copy of the desired geometry, merges it all and only at the end solidifies.This can be especially effective with patterns of a pattern.

    I heartily second this recommendation. We've had patterns that take about 20 minutes to regenerate when they were defined as a standard pattern. When they were redefined with the geometry pattern, the regeneration was so fast we were actually suspicious as to whether it was okay.

    The only thing that can give you troubles with this method is the pattern instances must be identical. You can't have instances that go "off the part" or result in partial copies, etc.
