Hi Michael

Just a little question about SketchUp Exporter. If you export only curves, you get nothing (Export don't work). If you include a solid or surface (s), in SketchUp you get the meshes but not the single curves.

Thanks,



George

Hi George, thanks for reporting that - yes the exporter does not handle curves at all, only surface data.

Hi Kevin, thanks for testing the FBX!

I believe that Max 9 is older than the current Max version which is Max 2009, is that correct?

I think that for Max 9 you need to update its FBX importer plug-in to the newest version to get rid of some of these problems, you can get the FBX plug-in here:

Sorry I forgot to mention that earlier.

>I believe that Max 9 is older than the current Max version which is Max 2009, is that correct?
Yep, since Max 9 there has been Max 2008 and Max 2009. So Max 9 is approx 2 yrs old.

Thanks for the link, I'll give the plugin a try and let you know if that gives a better result.

I'm not having any luck with the .fbx meshes from MoI in 3ds Max Design 2009. It loads in without any problems, and it looks great...no errors, the mesh looks exactly the same as in MoI. However, when I try to render it crashes 3ds Max. I say it crashes, in reality 3ds Max simply disappears from my desktop. This issue only happens when I try to render an imported .fbx file from MoI.

Maybe just save the file in MAx format, reload it and render? ;)

Hi Michael,

>> all in the same plane...

I got it work with some extra steps as you can see in the image
So it is possible in MOI3D

The other images are juwellery with a fasten method called 'Pavee'
(french for paving), and i use TangentSnapping to find a center-
point between 3 points

>>there will not likely be any solution
It's not a real problem,but if you find it i'll be happy

Hi Jeff, thanks for testing the FBX into Max Design 2009

Well that's kind of a bummer!

Can you test one thing please - when you export from MoI click the little arrow in the lower-left corner of the Meshing options dialog and try one version with "Weld vertices along edges" turned off and one with it turned on.

Does it only crash with the welding in a certain state, such as when it is turned on?

Hi Paolo,

> It's not a real problem,but if you find it i'll be happy

Can you please post a .3dm file with just those 3 cylinder pieces in it that you want to find the shared tangent between?

I'll take a look at it and see if I can make it do that or not.

It really helps a lot if you can post .3dm model files of your objects instead of just screenshots - I can't test directly with a screenshot but I can test directly with a .3dm file.

- Michael

Ok Michael,

Here they are,

One note:
On the ring Ove05.3dm the stones and Cylinders
are placed randomly (for learning practice)

Hi Paolo, thanks for posting the model data.

I do not believe that there is any true tangent solution possible to the situation you originally wanted between the cylinder end edges, since those 3 end circles of the cylinders are all in different planes.

I can see that Rhino gives you a solution anyway, however it is not really a fully correct solution, if you actually examine the result that you got in your bal7B.3dm file, you can see that those circles have a deviation between their tangents of about 1.5 degrees.

You can examine that by putting in some trimming lines like so:



Then slice your circles into arcs and run Rhino's gcon command:



The gcon command tells you that they are G1 since the error is below the default 3 degree angle tolerance in Rhino. However, that deviation of 1.5 degrees seems to be a pretty significant amount, I'm not really very comfortable with making a "solution" like that where there is no real solution available.


The other method that you showed is different - by framing your problem all in a single plane you have an actual legitimate solution in the other construction that you showed.

"Can you test one thing please - when you export from MoI click the little arrow in the lower-left corner of the Meshing options dialog and try one version with "Weld vertices along edges" turned off and one with it turned on."

Good call! It only crashes when the "Weld vertices along edges" is enabled for the .fbx export. If I disable that, I have no problems rendering/working with this mesh.

Thanks for testing that Jeff, that gives me a specific thing to focus on.

Does the "welding-on" crash happen on something really basic like a sphere?

If so then I will make a couple of different sphere tests for you to try so I can try to figure out how to have welding enabled without nuking Max.

Hi Michael,

Although I have not been active on forum for a while, I do look in regularly and have been using the beta builds.

Some nice improvements/additions.

I have seen some (at the moment) unrepeatable problems with trimming, so will let you know if I can eventually repeat them in a saved file (it was looking like the problem with the booleans, where it would not be correct on the first attempt).

Regards,

- Steve

Hi Steve, thanks!

I don't currently have any other reports of intermittent trim problems, like where it won't work but will work if you try it again. It would definitely help if you could get a reproducible example.

I'll keep my eyes open for that issue as well though.

Thanks,
- Michael
