Hi Burr, it can be tough to tell exactly how much difference there is between 2 curves just by trying to eyeball them.

The best way to do this will be in the next beta - there is a new Rebuild command there that has 2 modes in it, a "Rebuild to tolerance" mode, and a "Rebuild by # of points" mode.

If you care about keeping the rebuilt curve to be a controlled distance away from the original, then you will want to use the "Rebuild to tolerance" mode - instead of specifying a number of points, it instead lets you specify a distance value and when reconstructing the curve it will use as many points as needed to keep the rebuilt version within that distance of the original.

You will generally use the number of points method when you don't care so much about maintaining the distance and just want to really reduce point count.

Hi Burr, also why are you actually rebuilding the curve in that kind of an example where you want to maintain accuracy?

What is it that you plan to do to the curve after the rebuild?

- Michael

Well, that was embarrassingly easy.

Thanks, again.

Hi Michael.

>>>>>What is it that you plan to do to the curve after the rebuild?>>>

I am using it for correcting geometry from other sources. WHen recieving models, sometimes they are poorley created. Instead of having to re-create a complex model, I can use Moi to extract edges and rbuild only the poor parts. Also to get cleaner surfaces from poor geometry.

Also, many people are creating stuff for "CAD/CAM" wth these other programs like corel and adobe. THe geometry comes into my cad/cam package and can become unusable. ie; a function of creating a "contour", which takes base gemetry and creates a new"directional spline" object really gets bugard up with this stuff as the fnction runs at its own tolerance and these dxf files can mangle things up. Rebuilding that curve as a proper nurbs curve is very simple and makes for an easy camming operation.

I never run it on stuff I create in MoI. Unless I am trying to get rid of a seam that is interfering with a filet or a nice blend operation. I love blend for surfaces, so this tool is nice to have this work well. But when you adjust blend to go across multiple edges, then this will not be needed for that.

MoI for me is becoming very powerful for Analyzing and fixing existing geometry. THe new tolerance feature of rebuild curve will be very cool for me. This command is very useful to me.

Wow Michael, I can always depend on you doing it the better way :-)

Boy I can't wait for the next beta!

Between MoI, ZB3.5 and now ArtRage 3 Pro, I'll be straight for a good amount of time!

Oh man, I had never heard of Art Rage. I have no clue how to draw, but this is such a really nice toolset and price that I will just have to buy it.

I really love the stencils - I was tempted to buy SketchBook Pro for its stencils and rulers but AR's is way more powerful - especially now with the v3 features.

Not being familiar with v2.5, you're seeing really the best AR has ever been right from the beginning.

The new Stickers are also an awesome addition...

You have also in Zbrush incedible tools 2D , 2.5 D (PaintStop and the new QuickSketch) ;)

Yep that's why I'll be straight once Michael drops his latest with MoI.

I've been using ArtRage however long befoore ZB had PaintStop and QuickSketch.

Up next, Lightwave CORE - that's the final egg in my software basket...
