3D carved molding help

Post by jTr »

Drive rail and profile = no problem to generate curve, flat step, then arch. Got it.
Problem: I need a classic curled ball type end. Image attached.
As a 12+ year user of Sketchup, I can get pretty dang close. Problem is, too many holiday spots while extruding, so I get odd indentations. After 2 days trying with Sketchup, as well as an extremely poor result trying to import a photo to generate 3D model, I need some direction.
Should I:
A> use a drive rail to generate primary molding extrusion, then generate a dome to insert on each end, and blend to suit
B> Keep digging for a tutorial that will help me clean and blend the rough spots on existing attempt as shown
C> Pay someone that is well versed at generating 3D items such as this

(8 year VCPro veteran, just upgraded to Aspire, feeling green all over)

Thanks for any guidance / tips / directions to tutorials

I learn best from doing a specific task as you are trying to do. Therefore paying someone does not help me learn and I am never in favor of that option.

Have you seen this video

Hopefully Michael Mezalick will see this post, he is a two rail sweep master.

It seems like adding additional profiles to you two rail sweep at the point where it curls and then adding a dome is the way to go.

Perfect response - checked out that video, which really opened my eyes to the Vectric paradigm. Thousands of hours in Sketchup has it's methodology burned into my workflow, but seeing the light now in how to approach this in Aspire.
End result: Not perfect, but I got it done and am well on my way.
Just a few thousand hours more.... :mrgreen:

Many thanks!

Jeff
