How to model a twisted column with Moi?

 I think this is one of the most difficult situations so I would be very glad to hear that it can be done with MoI.   ***There is always a better way to do things... Just find your Moment of Inspiration*** Attachments:

 523.2 In reply to 523.1 You can explore this possibility Create a spire3D (a circle sweep along a rail) and use function Array Dir along a curve or Array Dir Circular :) --- Pilou Is beautiful that please without concept! My Gallery EDITED: 2 Apr 2007 by PILOU Attachments:

 Another tiny variant: - Step 1. Make a circular array - Step 2. Loft the shapes - Step 3. Build the column with the pieces. This last step is only for build an "real" column stone by stone. In the virtual world you can build the column in only one piece! :-) Attachments:

 523.6 In reply to 523.3 Hi David this is a great method. JTB check out the images that David attached - for the circular array he picked the center point of the profile as the center of the array. Normally this would replicate a bunch of objects on top of each other, but with the addition of a vertical step, it will stack the copies up in a column shape. Very good idea David! The other note that I'd make is that you'll probably need a fair number of sections for the loft, each section will probably need to be rotated by only a somewhat small amount from the previous one. This is because there is an "anti-twist" mechanism built into loft where it tries to minimize twist between 2 sections. So if you have a symmetrical shape that is rotated in say a larger 90 degree increment from each other, twist minimization would probably produce a totally straight loft. So you need a smaller increment between each section so that MoI won't be able to find a just straight connection between the profiles. Does that make sense? - Michael

 523.7 In reply to 523.1 The other thing that you can do is you can edit the "seam point" of the loft to purposely introduce twist. To do this, make some vertical copies of your profile curve, like with Array Dir. Now select them all and Loft, but don't push "Done" to exit the Loft quite yet. While you are still inside of Loft, look at the viewports - you should see some points displayed in there - these points are showing the current alignment points between each profile. You can go in there and click and drag on those points to relocate the alignment point to somewhere else. If you go an progressively do that to each section you will introduce a twist into the loft. Drag each point a little bit further around in one direction. Be careful not to click on a loft curve instead of the seam point - if you click on a loft curve (the curves will highlight as you move over them), it will reverse the direction of that curve, you don't want that in this case. This would allow you to make a somewhat less dense (less points in the surface geometry) twisted column since it would use fewer sections. - Michael

 523.8 In reply to 523.3 Very nice techniques, thanks for these tips.

 523.9 In reply to 523.6 Hi Michael: >This is because there is an "anti-twist" mechanism built into loft where it tries to minimize twist between 2 sections. Yes, I noted it. I suppose that it must to look for the optimized number of shapes... :-) at Pilou..... as soon as I´ve seen your picture I´ve remind the "churros" (spanish meal with flour, oil and salt....all blended and fried. Fantastic for the breakfast with coffee or chocolate....yum yum yum) :-P like that: EDITED: 2 Apr 2007 by DAVID Attachments:

 523.11 In reply to 523.10 I'm getting hungry now... :) Pilou, I guess you could make a temple to the breakfast Churros with your twisting column! - Michael

 Thank you all, for your ideas... This question was sent to me from a friend. He also sent me the answer from a 3dsmax newsgroup Obviously the answer was simple. The reason I am posting this here, is to show the power of MAX modifiers and why I keep asking/wishing for this kind of modeling history. I mean, MoI is great, but the modifier stack that Max has, is what we all need. So, wishlist item : a "TWIST" command in Construct panel, because it can be very useful. a "BEND" modifier would be nice too. I don't know if what I say can be done, or if mentioning MAX is not good. I would like to hear from Michael about tools like these. I mean, if they can be added to MoI since they are applied to a solid after it is created. For example, you make the circle and you extrude it but so far there is nothing more to do with it, except boolean ops. Is there any limitation to further adjustments of the shape?   ***There is always a better way to do things... Just find your Moment of Inspiration*** EDITED: 3 Apr 2007 by JTB Attachments:
