Here is my modifications of Elisei drawing of the volute. Still not quite happy with the flat top. some odd lines and curves with the smoothing. Still need to tweak the drawing.Any other ideas??

TEMP B.skp

Elisei Appreciate the drawings. What and how did you create the internal curves. I am going to have to recreate these with my CNC router and if you look at the volute the top of the eye is not a dome but a flat surface into blending into the edge of the spiral of the volute. Look at the second picture from the bottom. I have to recreate the exact 3d representation of this detail. That same detail is missing from the center piece volute. The detail and curve in the Z-axis if very important in reproducing this clock ornamentation.

Any other help or ideas are appreciated.

Thanks DrPhil

here is a better picture of the original volute

Sketchup file of helical voluteYou can see my previous post about how to draw clock ornamentation. With the help of Davidheim I figured out that the name of what I was trying to draw was a helical volute. There is next to nothing about drawing volutes in sketchup anywhere that I have searched or look. I am having trouble finishing to of the pieces of the included volute.

I have drawn the spiral with the help of the plugins CurveMaker and Fredo6 Curviloft, but I cannot figure out how to make the eye (cylinder) top match the compound curve of the volute. I am trying to match the drawing to the picture included. The helix is drawn with the ionic volute.

Secondly, not sure how to proceed to draw the curve that fills the inside of the helix like shown in the picture.i have tried some variations using extrude along rails but have not made what look right.

Help and ideas would be appreciated

Thank you Davidheim1. I will look at those extensions. already doing items on CNC router and exporting them as solids. I am using the the skp-to-dxf plugin by N. Bromham http://rhin.crai.archi.fr/rld/plugin_details.php?id=774 and the CamBam Export plugin from cerebral meltdown http://www.cerebralmeltdown.com/cncstuff/page2/cambam_export/default.htm.

I am having a problem naming the components in these parts to even begin where to look or how. Will look at those plugins. Any other idead or help would be appreciated.

Here is one item that I have already done

sketchup file of drawing

I am an intermediate user of sketchup and have used it to draw and make items with my cnc router and 3d printer, but I am at a lost of how to draw this item. It has the combination of round curve and helical components. need some help. I have a number of plugins including the engineering tool box and the extrusion tool kit, but have not found a way to draw this. Also have not found any examples because I not sure what name to use for it. I have included a pictures. Thanks for the help.
