Re: Inventor - Engraving on a sphere

04-07-2013 02:45 PM in reply to: 220610

Here's a sample of using a revolve to create part of a sphere and two methods of creating holes or embosses.  The hole is using a sketch the passes through the origin point at the center of the sphere and extrudes through the side of the sphere.  Then I applied a circular pattern of that hole.  The emboss was created using a surface that pierced the outside of the sphere and then a split face to isolate that circular face.  Then, I used a Thicken/Offset to make the embossed face with the edges perpendicular to the spherical face.

Again, thanks a lot!

Can you please save it in a version compatible with 2012 (which is what I'm using), says the database is a newer version and won't open the file.

 

Hopes this solves it!

Just like there's no wrap-to-sphere, there's also no save-to-earlier-version.

 

Unfortunately.

 

 

I had something a lot like this a year or so back.  I needed to engrave text into a sphere.  I wound up setting a plane for each letter tangent to the sphere and then extruding each letter separately to a second sphere that was inside the first one at the correct depth for the engraving.  Because each letter was done separately, there was minimal distortion, but it was extremely time consuming.

I think the OP's problem description is far easier than wrapping a text to a sphere, but since the OP is using an earlier release it would take a lot of work to document an example.

Yeah, no kidding.  I don't have an earlier version available.  If OP had 2013, this would be about a 5 minute solution to demonstrate., if I've understood his problem correctly.

OP -

 

Is this more or less what you're trying to accomplish?  If it is, I'll try and write up an illustrated how-to in the morning when I get back to work.  It'll be beer-thirty in ... 9 minutes now.  (But who's counting, right?)

Oops - just checked back in this morning, realized I hadn't attached a picture!  I guess I was a little too eager to get out of the office last night!

I have an academic license so I downloaded 2013, and I believe this solves all my problems, thanks a lot!

I can only hope I'll be able to help someone else like you helped me.

 

Again, since words can hardly express it, thanks.

Okay, since you've got 2013 now I'll just attach my file so you can see what I did.

 

The stuff before the thicken operation is a little clumsy - I could have done that cleaner.  Sketch 2 and the stuff after it should give you the info you need.

Re: Inventor - Engraving on a sphere

09-03-2013 03:07 AM in reply to: LT.Rusty

I'm aware this is a bit long after, but something isn't working.

I've also tried with the last file, "hole pattern on sphere.ipt".

Each time I try to create the rectangle pattern (I've also tried it after deleting the original pattern and then to re-do it according to the same options) it doesn't work. At best I get the holes but they're un-parallel to the surface, they're fixated to the same plane same as the original hole, which results in partial holes.

Can anyone please help?

 

Thanks!
