Spacer Posted November 24, 2015 Share Posted November 24, 2015 Hi, I have a sweep object( circular profile/ curving path in all planes). I want a map of wood grain to follow the direction. How to do this, please? I notice if I use the nurbz surfaces tool on the object, it creats 8 new Nurbz objects which all together represent the shape of the original object. should I map to there idividually? BTW, some of these are trimmed, some not(otherwise smooth surfaces). current incorrect mapping: After nurbz surface tool: thanks! Peter Link to comment Share on other sites More sharing options...
Tech Posted November 24, 2015 Share Posted November 24, 2015 Yes, you need Parametric Mapping, so first Polygonize your path so you get equal spaced points: Then Convert the Curve to a NURBS Curve, and Sweep as NURBS along the path: Convert to Plain Nurbs, and Edit the mapping: Does that help?

Andrew West Posted November 24, 2015 Share Posted November 24, 2015 After 25 years of using Form.z I am still learning tricks like this. Very useful. Link to comment Share on other sites More sharing options...
Tech Posted November 24, 2015 Share Posted November 24, 2015 Hi Andrew (et al), Another variation on the "above tutorial" can be found in our Tips of the Week: http://www.formz.com/support/tips/tip66.html Be sure to check out all of them to keep up to speed!

Spacer Posted December 3, 2015 Author Share Posted December 3, 2015 Great! Thanks. except i had to switch to my Mac, and there is no nurbz option on my axial sweep: Link to comment Share on other sites More sharing options...
Tech Posted December 3, 2015 Share Posted December 3, 2015 Hi Spacer, The "Use NURBS Control Points" option was added in version 8. If you would like to see this in action, you should download the 8.5 Trial... it's fully functional for 30 days Link to comment Share on other sites More sharing options...
Spacer Posted December 4, 2015 Author Share Posted December 4, 2015 i downloaded V8.5 on Oct 3 and didn't know about the 30 days. is that why it won't open on my Mac? or is it my OS?(10.06.8...) Link to comment Share on other sites More sharing options...
Tech Posted December 4, 2015 Share Posted December 4, 2015 Spacer, The minimum system requirement to run formZ8.5 on OSX is 10.7 (Lion) so it will not run on your current OS. Link to comment Share on other sites More sharing options...
Spacer Posted February 12, 2016 Author Share Posted February 12, 2016 Hi, I am getting back to this. I want to make a 2 ath sweep using two nurbz curves as paths in order to afterwards creat an object with parametric mapping as you described above. the line i want has both a straight and curves parts. when I make the nurbz curve xith the "N -curves" tool, I cannot get a part of the line to be perfectly straight then at point have a tangent for the curv and then become straight again. I attemp to use 4 and 6 click to first create a polyogaonalised path(as per your instructions), after Nurbzing it, I cannot get the desired result. any thoughts? nurbzcurbfromthis.fmz.zip thanks- Peter Link to comment Share on other sites More sharing options...

Pobo Posted February 13, 2016 Share Posted February 13, 2016 The tips are great as are the recommendations here. It's a shame they are not in sync though: the essential step mentioned in this thread - polygonize with equidistant points - is not mentioned at all in the tip.

Spacer Posted February 13, 2016 Author Share Posted February 13, 2016 well the tip makes it seem like there are different ways to create a nurbz object- the sinequanon of parametric mapping. i haven't tried yet different approaches. I just wanted to know if there was a way to 'isolate ' a staight line from a cuve in a nurbz curve.. then i was going to do a 2 path weep from two of those lines (which i need for my particular object)... i agree the tips are great.
