freeform

[summer3d]

Has anyone ever heard of the "freeform" supplementary package for surface modeling?
is a package to integrate design into modeling, but it seems not to be very practical to use.. .
someone who uses it or knows it has opinions on it...consile etc...to understand whether the usage limit is mine or the program.
Thank you

if it is the isdx module you mean, I find it very good (and honestly it doesn't seem particularly complicated to use)

isdx module (interactive surface design extension ).

it is not particularly complicated to use, but a ptc course to enter the scope of use is always useful.

Maybe if you are looking for pure design software maybe it would be better to go on other products.

I don't know in what cases you use it more, but in my case, where I often find myself in the manufacture of plastic parts, the method of creating surfaces that uses splines to trace the trajectories on which the surfaces flow is not helpful.
or better it would be nice to know that you can also use more geometric lines or shapes. .
the surfaces you can force them to run along the skeletons created with the above splines (which among other things must be quite simple... . obtained with few points otherwise the surfaces become more spaced and difficult to control)
but it seems to me that the obtainable surface is a bit random, in the sense that even if I put more control trajectories almost worse the situation because besides not getting homogeneous, continuous surfaces, I can not even control its shape exactly because the program reasons for interpolation.
I may not find the method to use them but also at the course I have seen that the lessons were little constructive and little practical....but more abstract...as if the modeling had more a comic value rather than technical....so bound by shapes, sizes and what else.
I'm sorry if I've been long but it's not even easy for me to explain and summarize the problem well.
I hope cmq of being clear.

I understand what you mean, unfortunately I can't answer you because I haven't left with isdx for almost two years.

the tool is quite powerful, you should find the way to get your geometries by combining the splines and points optimally, maybe first you have to create the geometry bone and then close the piece by piece, and successful work on the continuity of the curves.

I do not deny that sometimes I have had some difficulties, in fact some geometries are not simple and intuitive to realize, it is "see" the piece in the right way, and it is not easy.

Summer3d give us an example of what you want to shape so we can give you advice.
but use pro-and wildfire 2? If yes, know that the isdx has been improved in the latest versions of pro-e, today we are at wildfire 5.0.
However I try to give you advice even if I use isdx only when I meet the limits of advanced pro-e surfaces, i.e. practically never!
Know that you can support the surfaces of the isdx even with sketches or curves generated outside the isdx.
a useful thing is, as you say, create curves with few points, so that they are more easily controllable and with few ripples.
other useful thing is to control the goodness of the curvature with the instrument analysis > curve that if you set up saved saved shows you the trend of the curvature that dynamically updates if you move the control poles of the curve.
Of course, good surfaces are obtained if the curves on which they stand are good, at the surfaces of the isdx you can cmq give constraints of orthogonality, tangency and curvature compared to other surfaces. same thing goes for curves.
If you want I try to give you more advice even if I think what I told you is for you banal and already known. proponici a model so we try to do it together. would be a great exercise for everyone.
Bye.

the isdx tool is definitely very powerful and the tools mentioned I know them at information level (by the course) even if I haven't used them much, as well as the constraints of orthogonality surfaces etc.
However, I think it is a more suitable tool for patching (if you are able to use it well) rather than creating objects by caring for bulk and design.
I use the wf2...I can't post anything I have by hand but I give you a simple example:

new product (e.g. a new vacuum cleaner, a new electrodomestic, an electrical tool...) I have to model the shells (carter) of the new object by curating its design and containing the dimensions to the minimum of the encumbrances.

the post I have advanced was more than anything to tastare the level of practicality of the tool by someone who knows how to use it in technical and not only graphic...to understand if it is more convenient to use the traditional method or that of the isdx (to understand therefore advantages and disadvantages).
