Clean mesh modelling

Recommended Posts

Hi everybody

 

Looking at the work of real pro-modellers I am always struck by the clean meshes that they produce when they model. I myself can do nice enough models but with the different processes I use I always end up with horibble looking meshes and having to use two sided materials and so.

 

A short description of where some typical problems for me would start could be the following...

 

I usually start modelling in Autocad and import into Viz or Max either by linking the file or importing a DWG. I do this because I like the precision tools in ACAD - but it is a proces wich in it self is not the best way to produce clean meshes...

 

Also, I am not able to control the mesh when combining tools like mesh-smooth and multi-res/optimise in MAX. Another mesh killer is of course boolean operations.

 

I am ready to change horses in my aproach to modelling... but how to go about it?!?

 

Any tips or links to tuts?

 

Thanks

ras,

 

Once cad objects are imported, collapse to a mesh and or use the mesh edit. You may also want to merge objects prior into the max scene. If you don't or change thier names, then updating the link, re-inserts the cad objects. If you did'nt already know.

 

Try this! And you may have a better response posting in the viz or max areas, for further questions.

 

Modeling in cad adt is a good way to model architectural elements, but max and viz do have some comparable tools. Higher learning curve, however.

 

Good Luck

I do the same thing(modelling in AutoCad then go to Viz)but in my case there´s a different reason to do that; I´m using an AutoCad plugin called Archi3D that make very easy to convert from top view 2D plans to 3D, it also make terrains, ladders windows and everything else in Architetural Design, so I do not want to change the way I´m doing but this tip can make a good difference in my job

Hi guys

 

Thanks for your replies. I think i haven´t been clear enough...

 

What I mean is actually that I am not able to produce meshes like this Audi A4 ( http://www.cgarchitect.com/forum/filepush.asp?file=a4_wire_1.jpg )

from the eshop in this forum. It seems more or less impossible for me to produce vertex-optimized meshes and still keep those crisp and clear subdivisions...

 

I am looking for a basic modelling approach that will help me produce clean meshes like for example the Audi. I realize that it is different when modelling architecture but I have seen some people produce beautiful meshes that would even be useful in themselves when presenting the architecture...

 

?

 

Thanks

Hi Zortea

 

Well, it´s not really about the Audi. I don´t know - its just that the mesh only consists of deliberatly spaced foursided polygons, which is something you really can´t say about many of my own architectural models - especially when using the multires modifier or something similar. I am sure that great modellers don´t use optimization modifiers at all, but maybe my message is not really coming across... Hmm, I don´t really know how else to explain myself. Maybe it´s just so basic that everybody else knows already?

 

I am hoping that someone could give some general guidelines on how to keep your meshes neat and clean while still complex.

 

...However, odd enough - I am doing a schoolproject at the moment involving an Audi dealership and would be very greatful if you would send me an A4 model - and I would be even more greatfull if you had a TT?!? If the filesize exceeds 1 MB my hotmail will not accept it. We use MAX and Viz at my school and I am able to read any of the filetypes that can be importet in those programs. Thanks Zortea.

 

Anyway - still looking for tuts on making neat and clean mesh-modelling in general - not software specific. Anyone?!?

I model everything in Autocad too. I like the precision, plus I started with 2D doing construction documents for an architect, so I'm efficient with that method. Of course, my models aren't because they're all solids, which means extra backfaces. Hey, I've been looking for nice sedans for my renderings. Are they available somewhere for download?

Hi..just for your information and reference.

I have same problem before especially using autocadd as a modeller but then i find out and started using Rhino3D which is very much compatible with autocadd. So what happen is i used 2D for autocad then import to Rhino3d for Modelling because it can do the extruded Solids to a Polysurfaces which actually can modify easily.

 

Both can import & export, can imput coordinates & nurbs too.

 

FYI,

Modeling in Autocad seems to be much easier than in Max because pretty much everybody that does Arch Viz had learned autocad first and is comfortable in it. Unfortunately this is quite a misconception. Modeling in max is quite accurate when using snaps and the edit poly tools are making Max a lot faster than Autocad. It does require a bit of getting used to but I bet anybody can make the transition in less than a week. And as an added value to all this, you have clean meshes from the start and you don't spend any time importing and cleaning stuff. In top of all of these, if you lean a bit of scripting you can be the fastest modeler on the block ;)

 

Check http://evermotion.org/index.php?unfold=tutorials for their tutorials as they have a few good ones on interiors that use edit poly.

 

And everybody is right, try to NEVER USE BOOLEANS in Max. All goes haywire after that...

I haven't used pro booleans extensively so I cannot speak about them. What I was referring to were the max default booleans.

 

If i needed to use booleans i would usually detach the faces that needed the operation, run the boolean and attach it back to the main object. So there are workarounds but sometimes is just easier to do the poly model and kill a face.
