I have always drawn my objects in Adobe Illustrator and saved them as AI files. I then load them into TS where they first appear as draw panel items which I can then extrude (sweep) or lathe, etc. It has always worked fine.
My reason for working in Illustrator is simple: I have been working in Illustrator for over 12 years and can really move fast on complex shapes. There are more and better tools there for that kind of work.
Today, however I brought over a complex shape to be extruded (see upper left corner in image below) and find it has all kinds of flaws in it. They don't show up when I render on model side using LightWorks, but they DO show up using Vray. Also, when I mouse over the shape in workspace edit, half the shape lights up, not all of it and the flaws light up as well. The flaws do not extrude - they are like thin (2d) skins (or missing skin) on the flat surfaces at top and bottom of extruded shape.
1st question: any clues about what is happening or possible fixes? I have carefully examined all the points and they are fine in Illustrator. They look fine in TS too and I can manipulate them with the tools (though I don't need to.)
2nd question: to bring these in, I must use the "ts6 files" button on Model side and choose "load". Is there a better way to bring in AI files? Can they be brought into Workspace?
Thanks again for any suggestions. |

Hi,
This thread holds the elusive answer to the great mystery:

Make sure your AI export is "grouped" before you export.
Try that and see if it makes a differences.
Paths in vectors can behave strangely if they are not grouped.
Currently, the only way to bring in AI or EPS files is through the model side of tS 7.xx
I don't know of any work around. |

Thanks, 3d Visuals Dude,
Wow, what complexity! I was just coming back to post the fact that I found a solution myself, but the link you provided is a keeper and will go in my TIRED* file.
*(TrueSpace Is Really Extremely Detailed).
I finally noticed that some control points which were very close together in Illustrator were landing on top of one another when loading into TS. So in Illustrator I tried enlarging the whole drawing 400% before saving and when it loaded into TS, the control points were no longer touching and the problem went away. Interestingly, the object did not appear overall larger when loaded in TS, just more accurate.
Thanks again |

Thanks, jamesmc,
This was a single object - just one continuous curve, so not possible to group. However, I'll remember the rule for future. Thanks. |

Glad you solved your problem whatever it takes to work, works. :)
I'd like to point out though that your single object was composed of many paths even though it was one object.
In other words it was not grouped.
Look at the image I made of your screen shot posted here. All of those nodes I circled are end of path nodes. I also red circled the path nodes on the white object.
Now look at the left hand white object. It is a clone of the right hand object.
Notice anything different? There are no nodes on the left white lined object it is closed path. The white lined object on the right is an open path.
The difference is that the one on the left is grouped, the one on the isn't grouped.
Hope that helps in the future, besides I had to explain what I was referring to. heh |

I thought I had this solved, but I found that the problem kept returning. Even after I had fixed the objects, a while later, the same skin weirdness re-appeared on the same objects. I tried every solution suggested in this thread, but nothing worked. I even deleted and then re-added new faces. I finally figured out that the problem always returned after I had "encapsulated objects in 3D" (workspace), so I experimented with glue-as-sibling (model), which the manual says is equivilent.
Success! Now the problem has not re-appeared. I have run the experiment several times with consistent results. Encapsulate messes up the flat faces of extruded objects. In the image below - left pair are glued, right pair are encapsulated. I would be interested, of course, to know if anyone can reproduce this error or if it is just my combination of hardware and software.
Thanks again. |

I don't know the answer to this but noticed "encapsulated objects in 3D (workspace)" and being used on the Modeling side. Using functions on the workSpace side then bringing them back to the Older Modeler side is always asking for trouble. The "glue-as-sibling" is a Modeler side function and should have been used instead. The powers to be can give you a definitive answer but my own rule is don't mix the versions.
