Origin (move), -or- "did" the pooch on this one...

Hello,

OK, this is going to be boring. Also, you will ask yourself
"why did he do that"?

I imported an STL as a solid body (it's a diamond gemstone). I
only needed the crown and facets.

Using the imported solid body, I assigned reference planes to
each facet (on their respective surface). Insert a sketch, select the
facet face, convert entities and got my new sketch. Extruded this to
1mm thick (for those interested, I did it "reversed" so that each
facet would merge into the next. OK, got the entire crown. Now...

When I delete the "original"solid body, I loose the reference
for all the planes (as they were converted entities), so now I have an
entire assembly tree with exclamation points, and no reference
"origin" for the model. I can keep working with this, as all the other
features are relative to the solid, but it's bugging the hell out of
me having all these exclamation points. How can I move the model (or
origin) let's say to the center of the "top flat" face, and get rid of
all the exclamations?

Thank you for your help, and yes, I've already called myself
all the "dumb f*** names...

If you exported it out as a dumb part and bring it back in as you did, then
the link to the original will be lost along with the exclamations. I would
have hidden, suppressed or made transparent the original if you didn't want
to see it.

Yes, that will happen, you deleted all you references so... one way to
get rid of the exclamation points is to export the body as a parasolid
x_t and reimport it (and of course delete all the ref planes).
As for your origin.. well, you could also predefine a coordinate system
and when you export the parasolid, you again use the options tab to
select the coordinate system (origin).

I can imagine how you are going about this but I'd suggest (although I'm
sure it works) that you not approach each facet as a solid extrusion,..
use a planar surface and after you have all your faces (btw, if the data
is symmetrical, you could establish a centerline and copy/rotate the
faces), then knit the surfaces into a solid.

BTW, here is a solid model of a diamond I did many years ago..

Hi Paul,

Thanks for the info and the example part. I examined your
design, and re-created what I was working on using the same
techniques. Much better result! Thank you again.
