Cross section curves

[dannytso]

Hi 

I come from the custom body part fitting industry.

It would be great to have a function that quickly creates cross sectional curves on the body part in question which can then be lofted into a smooth surface of the object to be fitted. T spline sculpting can then be used to manipulate the surface by the practitioner or lab to get a comfortable professional fit and finish. I find the more cross sectional curves involved in the loft leads to a closer and more accurate fit. Perhaps there can be an option to choose how many cross sectional curves to be lofted and the distance between each curve? 

I used Rhino and they have a Contour function that creates these curves immediately. I find Fusion has a ways to go as it gets quite slow when the number of curves I make increases. I am on a Macbook Pro 2.6 Core i7 with 16 GB of RAM and 1gig video card. 

Love this program. Thanks a lot Autodesk and associates!

Edit: This is assuming the above technique is the best way to create a custom fitted surface to a human body part such as the foot. 

If there is another way that is less time consuming I would be interested in learning!

Hey, this sounds like a great idea!  Hopefully being a fairly straightforward implementation, it should vastly increase the usability of Tsplines for practically any imported mesh, being the missing ingredient for the Pull Tspline operation. 

Here's an example of a very high quality Tspline mesh that was created by the method of lofting between multiple mesh intersect profiles, getting close to the final geometry, BEFORE doing the Tspline pull. 

This method is further illustrated on this thread: http://forums.autodesk.com/t5/design-and-documentation/foot-insole-modelling/td-p/5715117

Being able to do this almost instantly by Orthometrix's idea seems like a great no-brainer 😉

TBH this was your idea Jesse. Sorry I should have redirected this back to you because you are the one deserving of the credit. Thanks for the response. Hope you are doing well!

And btw I love this technique. Since you taught me I have discovered other programs that are able to perform this same task. If only there was a short cut to get the cross sectional curves faster and at a sufficient amount for lazy guys like me!

I don't think I would have ever thought of a new feature that would make the "MRI like...except further apart" profile slices/curves automatically, especially never working with Rhino etc. to know similar powerful features exist elsewhere.  And you put the idea up, which is more than half the battle I think 😉  I put the picture up to let people get an idea of a quality fitting Tspline mesh.  We should maybe also put up a picture of a loft from many cross sectional curves to illustrate the idea more.  Let's hope it really catches fire!

BTW, I'm doing great, and hope the same for you 🙂

I guess another important detail is that as you mentioned doing, a Tspline pull is not necessary afterwards if the multiprofile loft already fits sufficiently for the application like an orthotic insole, although the pull operation is always available to get the last bit if conformity accuracy.

Wow just read your other post, that's awesome you got another program working.  Yeah would be great to get this implemented in Fusion.  Was cool that you brought the question up so that we could both learn from it 🙂

We have a similar tool in the Mesh workspace.  I'd like to expand the functionality, make the cross section curves more useable. Putting this in the backlog.  Release date TBD.
