CAT-CAD 01.03 WIP

About Modeling
Model is created using Rhinoceros 3.3 . Everything is free 3D handsketch - not based on a blueprints .
Concept of this model is created also from me - it`s hybrid between Caterpillar and Bobcat .
In mechanical point of view - everything is properly of course .
When I was approx. on 30-33% I try to increase the quality of the displayed mesh ... that was to hard for my 3.2GHz Pentium 4 , after some calculations my laptop just switch off ...
I loose all unsaved data - but that was smaller problem , i loose the only background reference image and all displayed mesh ... rebuilding of the display mesh even with lowest parameters was slow and hard ...
To restore the position , the scale factor and rotation angle of reference was impossible - so this hand sketch becomes more free ...
For modelig i use polysurfaces , i try meshes but Rhino generate some non symetrical surfaces even when source curves are mirrored , it was necessary to sketch some extra section for details result of "sweep" operations .
Converting model from surfaces to polysufrace and using of fillets make those model 232 Mb , clear stuff 200 Mb in 3dm format ( full - not saved small ) .

About Export / Mesh Optimization
... on my laptop ( the only equipment i got for a moment ) I cannot execute some cool rendering ...
I please `dangeruss for 3D support - he`s very talent 3D designer and just amazing in materials / composing in vechicle scenes ... he`s also 3DstudioMAX user , like me .
I was surprised when he accepted ( thanks Russ ) . Russ becomes very serious person also , so he make first import of the model in MAX using PowerTranslator ( powerless translator ) .
Just like he said : "... import was hard and painful ..." , result was discouraging - wrong surfaces directions , hard edges , wrong normals ... just amazing .
I cannot please somebody loosing time for rendering such a mesh ( Russ less ) . I please Russ to give me 2-3 days to try manual export - problematical parts are converted to meshes and exported using Rhino only .
Russ optimize smooth parts and replace wrong exported details for testing scene on up .

I wanna also thanks to Bobi ( from 3D Bulgaria ) for Rhino export advices ( a lot of options there - combinations much more - full madhouse )


thanks and respect


... well that`s it ... enjoy the testing pic on up ...
