Aparently not a solid form?
-
Just to be clear on why you need the faces the right way around, apart from many rendering programs having problems with back faces, 3d printing needs to know.
Imagine a cube with a sphere inside it, if the back faces of the cube face in and the sphere face out, the printing software knows that you have a cube with a sphere shaped void inside, rather than a solid cube with a solid ball inside it.

Ok did the fix on the smal numbers.
You lost me on how you did that, maybe in a couple of years I'll understand that stuff better.
I just deleted the numbers and redid flat numbers directly on the surface exploded them and extruded them.
Probably the long way round but it worked.Just going to check all the surfaces again and try to export it.
Thanks again!

What did I lose you on? The copied component thing?
Here I made a ruler component full sized (the little one), made a copy and scaled the copy up (the large one) The large copy is open for editing.
After adding the 3D text for the company name, you can see it also appears on the original copy as well.
After closing the large one to get out of edit mode and deleting it, Zoom Extents takes us back down to the original one.
You didn't need to redo the numbers. Just finish the job.

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.

No, just right-click the instance then make unique.

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.
