I have no clue as to the answers to those questions, but here is a thread that works on the
same type thing you are looking and wanting to do. So maybe you will find a solution there.
many thanks Scott McFadden
i moved the topic from sketching section to surfacing section to be more effective.
but i still don't know if Dassault will develop the G2,3,4 curves or it will be a matter of fancy!
i also thanks Nurkholish who send me a link to a great and simple tool for creating G2 curves
really cool and simple software.
i hope we will see this kind of curves in SW shortly.
Solidworks offers a G2 sketch constraint and the surfacing tools practically all have a G2 boundary condition. The things that are harder to do in Solidworks in my opinion, is working low span and to higher continuity levels, but you must understand that the importance of both of these are... debated.
What I mean by that is that it's very hard for most products to be able to tell the difference between G2 and higher levels of continuity and the usage of many spans is not really that problematic most of the time. Only becomes a problem when you want to do direct modeling, I don't even think CAM or Simulation programs have any beef with a surface that has 60 spans, as long as a software algorithm generated it to some set tolerance, it'll probably be smooth enough without much of any anomalies.
So the real question is perhaps: should Solidworks include direct modeling? Well there's the Freeform tool already and it's a step in that direction but currently no it does not. Solidworks' foundation are the parametric modeling approach that is inherently different from direct modeling workflows. So desiring this might be unrealistic?
Lattice is a good idea I think, maybe include that in the Freeform tool? But lattices on nurbs geometry (which Solidworks also uses) is very tricky and isn't so easy as a poly modeler including a lattice modifier. I know Alias has the transformer rig but I don't know the success rate of that tool at all.
Displacement mapping sounds like a good idea too. Maybe maybe?
thanks Kevin De Smet
what i intended to say is why solidworks doesn't introduce a new curve sketch tool that basically support continuity in its real form like those in alias or rhino
or even moi ?
i know that SW support G2 continouty for surfaces in all its tools , i didn't talk about that.
i wnat to talk about wireframe modeling, that u'll find the spline tool is hard and not convince for the job.
i know that u can do some nice curves with this tool but it still isn't the optimum method of doing things.
Since you are so interested in product design, take a look at SW as a product itself. It is a product driven by parameters determined by a marketing organisation. Marketing has determined the price point and features they wish to sell to the CAD market.
Yes, SW can be improved, but SW just hasn't decided to do it. There are things UG and Pro/E have been doing for over ten years that SW hasn't even begun to catch up with. They would be simple to implement but they simply have decided it is not important to them.
and now i get the answer.
