Aparently not a solid form?

Oh very clever indeed...
I didn't know that original components mirrored their copies.
very helpful.
I guess the obvious solution to avoiding that would be to explode the copy and re-component it under a different name?I'm sure I'm doing a lot of things the long way round but these little tips are very helpful.
I draw a lot of small things and leverage this behavior all the time. It even useful in many cases without the scaling bit.
Gilles is right. Don't explode and re-component. Just right click and choose Make Unique.
I was having a little play with my ruler and ended up with this. There are a lot of tiny faces in it that SketchUp wouldn't have created if I'd tried to draw them at 1:1.

Thanks again!
I've exported to .igs file but I don't have a program to test the results.
Could one of you have a look at it? -
Oh...
Now I've added some new features and my exporter says "model contains non-solid elements"
but now I'm completely at a los as to why.
there are no imbedded objects or components.
and solid inspector can't find anything.
-
Can you see that bit just there...no no, next to the other bit..back a bit and round to the left....yep you got it, good, now fix that and it should be fine.
-
Nope, been there, done that, skipped on the t-shirt though.
I've checked everything from every possible angle, yes just a little more to the left and so on and so on...
Truly inexplicable from my limited knowledge of this program.Thanks for the constructive advice. I think I'll wait for something truly clever though.
-
Could you share the model in V8?
-
What are you using to export the IGS file? What are you using to check it? I wonder if it's the exporter that is causing your problem.

Truly clever would be posting the model or, at the very least, an image so we have some semblance of chance of seeing what is wrong.
-
OK found it. although only by chance. It seemed to be a microscopic tear in the sketch time continuum. Something on the surface that was there but at the same time not there. Possibly a previously unknown spontaneous transitioning sketch-quantum particle.

I can export it through a plug in I got here off the forum iges_export.rb
I downloaded a trial version of Autodesk Maya 2014 but I can't see a damn thing when I open the file and the program is well... massive ,new and overwhelming quite frankly.
The iges_export seemed to export without any errors and the file size would indicate that there is a substantial file there (9mb) too big for here. I could scale down and re-export it and see how small I can get the file... -
rescaling seems to have no effect on the resulting exported .igs file size. I've gone down by a factor of 1000 now and no difference.
-
I wouldn't expect scaling the model to reduce the file size because scaling doesn't reduce the number of entities (edges and faces) in the model.
-
9meg is probably about right. You could zip it and post it or PM it.
You might find the a simple .igs viewer more useful. such as http://igsviewer.com/
-
I just noticed the reason you can't see a damn thing in maya, as you put it, might be because in the file you posted earlier the calipers are 28m from the origin, so when you open it it is probably tiny and way off to the side somewhere.
Always model close to the global origin.
-
It's likely that the model wound up 28m from the origin due to scaling up to work on tiny geometry and back down again. If you do that using the Scale tool, use the same handle for both scaling up and back down. As I wrote about in an earlier post, I leave the original component where it sits and scale up a copy. Once finished editing the enlarged copy, I get out of edit mode and delete the big one. This leaves the original small component in place near the origin with all of the editing done.
An alternative method of scaling up and back down is via the Tape Measure tool. Measure a known length making sure to click at each end. Type a new, larger length and hit Enter. When you are ready to scale back down, measure the same distance and type the correct distance. Hit Enter. The model will get scaled up and back down maintaining the same position relative to the axes. and origin.

I keep getting an error from the IGS viewer and it freezes up but only when I try to open this one file. If I make a simple shape and export it to the viewer it works fine (thanks for that tip
).
Here is a copy of my .skp file which doesn't seem to want to export properly. I'm at my wits end
The model had been moved back to the planar center several days ago when I was made aware of the scaling mistake I had made.
Any help would be very appreciated.I suspect something has gone wrong with the surface of the main calliper piece as is exhibits strange characteristics when I try to alter it in any way.
I tried making engraved (extruded) lines on the surface but this just caused a whole mess of errors that when auto-corrected always resulted in the top surface being deleted and the ends of the tiny engraved "ditches" to be deleted as well. Very strange. The simple pattern I've now successfully placed on the surface was very tedious. The lines kept drawing not directly on the surface so that I had to draw almost all of them individually. Copying sections of them produced thousands of tiny mistakes in the solid inspector.
Thanks for any help.

Please, post the model in V8.

I wonder if the scaling has caused you some issues. The definitions of the components are at different scales. In your V13 as I downloaded it, the main bar component measures 17800mm long overall. It is scaled up from the original size. Component #2 is also scaled up from its original size. Their component definitions were created when those components were correctly sized. The other four component definitions were created at this scaled up size. Perhaps the IGS file shows the components at their definition-defined sizes?
The fix at this stage would be to correct the scale of the entire model--scale back down to life size--then explode the four components that need their definitions corrected and make new components of them.
This scale thing is another reason I use the process I've described when working on small components. It avoids this problem altogether.

Thank you all very much for all your help! I've manged to create a file that I can export and use and am now with a very much altered design in the prototyping stage.
