I was just thinking to say sorry we took over your post that sometimes happens when me and ken get going on a topic ...anyway nice start and at least you made some$$$... work with 3dengrave and figure it out as there's alot you can do with it and when you feel you may want more look into rhino or one of the other softwares and above all keep posting!

Hi cgator2,

That's come up great for your first rotary, Well done!!
It's always really hard that first time around, so Congrats!!

Borders, edges & raised sections all take time, practice & observation to get a feel for how thick something on screen will be once it's milled.

If you've already got some good examples in metal, then measure all of their widths, thickness & depths.
Add a bit more onto those dimensions to allow for shrinkages due to casting & clean up & that'll give you a good start point.
This is basically what's refereed to in CAD as "Reverse Engineering" the piece...
...as Bench Jewellers, we're pretty much doing this every time we tackle a Remake.

Once you've got those "start point" measurements, then make the model in 3D Engrave & mill it as a sample to see & test your results.
Study the wax, measure it...anything that's over, under or doesn't look right, adjust it in 3D Engrave.
It'll be a case of slight refinements along the way until you've developed yourself a "Template" to make all the models from.

HTH, Colin

Great job on your 1st rotary. One thing when you have this new tool is you always want to go deep on the relief. Surprisingly less is better. As Colin suggested take a look at class rings and charms to get a feel.
This will help the finish and less chance of distortion of edges and walls.

The sport charms you see out there most the time only have a few 10ths of a mm in the depth. sandblasted background and lapped top surface. Looks great!!

Again Great work and sounds like a good payday also. Very Happy
