  1. If you're really looking for a parts, assemblies and drawings kind of functionality and workflow I don't believe you can get much cheaper than Solidworks (and get a better price for value, either!) Alibre's 99$ stunt is over now right? Still I suppose for 2500 it is still the most affordable bet.

    3ds Max

    While the value of 3ds Max may be less than Alias, Rhino or Solidworks. I don't think it deserves as much beef as it does, by industrial designers. Polygons are flexible, subdivision surfaces are flexible. Can you have them tooled? Probably not. But there's more to product design then that final step, I think a package like 3ds Max for the design phase at about the point of sketches or right after some sketches, is a possibility.
  3. That actually sounds like a good work-flow there, I can imagine using Max for that. I know Max can import .IGES files so maybe it can also export them, that would work with Solidworks. Also, is your model an editable nurbs, editable poly or editable patch object? Because that will matter too. If it's an editable poly (which I am assuming it will be) then that's indeed a problem, as an .STL it comes in as "STL Graphics" and it's useless for anything but a pretty picture, I've been there my friend! I'm afraid I can't help you but maybe somebody around these forums has a solution for how to go from a polygon object into a nurbs-based solid or surface model. That would be sweet. P.S. Try right-clicking your object in 3ds Max itself and converting it to an editable nurbs, just for kicks, what does it do?
  4. Not to sound like some pirating maniac -- but if I download a piece of software at home through a torrent and I end up liking that piece of software, odds are I'll recommend a seat or two at the office making that software company revenue accordingly. Not that I'm into the whole pirating software thing...
  5. I don't have an answer to your question, but, seeing the new interface it does look a little better than it was before for Pro/E. However not nearly to the extent our Pro/E reseller told us it would be - and I got excited for it - awwww.
  6. SolidWorks surfacing -- in my opinion, is extremely powerful but not suitable for class A requirements in aesthetics or aerodynamics. So I'd be reluctant to do a coca cola bottle or airplane wing in SolidWorks. There's really just one reason: the inability to get access to your spline degree and surface hulls/cvs/isoparms. You can do a few things with isoparms using "Face Curves" but it's limited. And then there's "Freeform" which allows you to add and remove isoparms and cvs but... not existing ones or at least not easily and it's jammed into one feature/operation. But surfacing in SolidWorks is above all else just fun, putting curvature combs on a spline is a snap and tweaking tangents on your spline points is both reliable, powerful and easy and the same goes for the vector magnitudes. It's certainly not something to dismiss as I think ever since 2007 it can do a lot of stuff. Boundary and Fill surface are both especially powerful. Here's a mould I made a few months ago using alotta surfacing: http://www.kevboy.metalsoup.com/Matrijs_Kern.PDF And a rendering I did in Photoview 360 (part of Solidworks Pro and Premium): http://www.solidworksgallery.com/index.php...8f903f3fd2a.jpg

    Which Modelling Program?

    I believe Studio Tools' 2010 releases shook up the prices a little. Alias Design now starts at 4000$ but from what I've read, it doesn't do much of anything at all - so you're looking at Alias Surface which runs for 20000$ so that's quite expensive. Then Alias Automotive supposedly goes for 65000$ which is only affordable for behemoths. I must say that Studio Tools does seem to be very good at what it does, and that's design with NURBS.

    3d Modeling Help

    Good point! remember that rendering is the process of calculating your lights' rays and material properties that are affected by those rays (such as reflections, refractions, colors, etc...) The total might add up to something along the lines of: Modeling - 20% Materials - 30% Lighting - 50% It depends on the scene too, of course, some scenes can get away with sub-par lighting because the modeling is par-excellence. But don't count on your excellent modeling skills to be able to offset poor lighting all the time

    3d Modeling Help

    What skinny said is absolutely right, but also remember photorealistic renderings are often also done in software such as Maya, 3ds Max or Modo - amongst others in that genre. These programs have the uniqueness that they don't often produce manufacturable geometry so they are created in the computer, and often stay in it (rapid proto being the exception) The benefit is that for a render, you want to reduce your render times, so objects far away from the camera can easily be modeled with less detail than objects up-front using polygons and subdivision surfaces. It's also much easier to texture, unwrapping flat polygons unto a 2D plane to add texture that will flow seamlessly over your models.
  10. A history tree isn't always an additive value, it can often be a burden. Rhino can record history if you want it to for a certain operation, and solidThinking has full history capabilities. Cyber, as for your statement - I didn't really quite think of it that way before, but to get the best smoothness isn't it always working OFF your model and tweaking its curves that you then trimmed or something? Basically making the whole process quite off the model unlike polygons (excluding subdivision surfaces)

    Heal Edges Tool In Solidworks

    Heal Edges has saved my butt a million times over, just a fantastic feature for healing up your geometry after some hard core surfacing operations where you want or even require good edges, and require them fast. The only downside is, that it's very poor in a parametric sense. What I mean by that is, if you rollback to a feature before a heal edge and change something (it can be small and totally unrelated on the other side of your part) then chances are very high that your heal edge features that come after that feature will fail. Your model topology had changed and it's a little like Rainier Wolfcastle from The Simpons would exclaim: "My solid!!! The heal edges do nothzink!"
  12. Even though I ain't that good at it, and it takes a lot of skill, I have to go for polygon. Nothing compares to actually manipulating vertices, edges and faces directly - right there - on your 3D model. Sculpting is a little to freeflowing, I'd love to take a real clay modeling class though and then maybe get into "digital clay" software like mudbox and sensable's freeform modeling, for like implants and fake dentures and stuff - that stuff is slick!
  13. Not at all, but I have seen a kickass video using a really exciting piece of hardware/software by sensable technologies: http://www.sensable.com/documents/Gallerie...o_WithAudio.zip Is this going to be a one time project or a long term investment with tens of shoes and several months or years of doing that kind of stuff? That makes all the difference here, right

    Catia Imagine And Shape Tool

    As far as I've seen, Catia's Imagine and Shape (as they say in one of their demo videos) is based on subdivision surfaces. Now, subdivision surfaces have come a long long way and have really old roots. Jelle, you say Catia's can keep G2 all over? Even over things like extraordinary vertices? (Don't know EXACTLY what they are - just know they can cause issues esp. with subdivision surfaces) They're very popular in animation because you have a low-poly cage to work with for animation but I don't think they generate manufacturing quality geometry, making it purely a conceptual design tool. But I could be wrong about Catia's implementation. I'm intrigued! p.s. hello guys, my first post here
