 2626.41 In reply to 2626.40 Hi Pilou, > Precision is given by a point Array curve/ Ellipse -->radius > base of the cone 3D so 2 decimal point after unity ;) You didn't include a 3DM model file, so I'm not completely sure, but I think your method may result in cones that are not touching each other exactly. For example if 2 cones are touching each other like this: But then 2 other cones are touching each other like this: Then the way that your intersected results touch between each piece will be not completely uniform. That may make that result unsuitable for architectural construction. The other thing is it looks like your result makes curved surface pieces? Often times this kind of paneling for architectural design it is desired to have planar pieces for the construction. It is not unusual for architectural design to have some special requirements beyond just making it look good - I think it is possible that your method may not meet those requirements. But it does look like a good way to get a visualization of something that looks similar to the desired result though! - Michael Attachments:

 2626.42 In reply to 2626.41 Seems remember my cones were perfectly fitting! (0.01 cm) I will remake that ;) Yes it's not planar of course : in this case must be hand drawing :) EDITED: 12 May 2009 by PILOU

 2626.43 In reply to 2626.42 Hi Pilou, > Seems remember my cones were perfectly fitting! (0.01 cm) You mean you measured each one to make sure? It looked like you used ArrayCurve to distribute the cones - like I was discussing earlier when you use ArrayCurve it distributes things at equal distances as traveled along the curve. The distance "as traveled along the curve" and the "straight line" distance between the centers of the cones are different things. - Michael

 here the 3Dm I don't use polyline : just array curve triangles are over the spline with 0.01 cm so just drop down between each base triangle there is 0.01 cm EDITED: 12 May 2009 by PILOU Attachments:

 2626.45 In reply to 2626.44 Hi Pilou, in your example file the cone centers are not all at the same "straight line" distance from one another. For example here I drew 2 lines in between some of the cone tips. This line is 1.13 units long (actually 1.1263 with more digits if you open up the size edit panel). This line is 1.11 units long (more digits: 1.1143): So actually more than 0.01 units deviation between them. It basically needs a different technique, to generate a set of lines that are all equal sized, to get better uniformity in the results. - Michael Attachments:

 2626.46 In reply to 2626.45 yes it's the price to use the array curve methode :) 0.02 cm for a building it's not the painting :) Maybe I willl find a better method

 2626.47 In reply to 2626.46 Hi Pilou - for construction the real problem is that for different kinds of path curves the amount of error with your method will be unknown until you measure each thing. For a rendering or visualization purposes only, that should be ok but probably not as a basis for a physical construction. Array curve just is not the right tool for this particular job - it does something different (making equal distances as traveled along a curve) than what is actually needed in this particular problem. - Michael

 Thanks Frenchy for your dedication to the cause! However I think it was really the principle I was addressing not specifically solely the triangle shape but a method that could be used that with any shape (like the tank tread example) that just used two end points in a straight line to determin the start and end of each segment. But good thinking outside the box!! Michael- yup i think you have understood me on my snapping point. Here is a better example - I just want to snap the end point of the line to the implied intersection between the radius of the base point of the line and the curve im intersecting to. Currently point will just slide up and down the curve which is useful in many cases but would be good to also have this intersection snap too. I think a picture is definately worth a 1000 words in this case!..... Re the straight line snap I can see the dificulty in determining the exact measurements for the implied circular intersections for an even split but i guess it would be easier for a purely fixed size measurement, that would save a fair bit of manual placing and rotating.

 2626.49 In reply to 2626.48 < not specifically solely the triangle shape of course :) the damned thing is that : the "Array curve" seems works fine with a "circle" :) EDITED: 13 May 2009 by PILOU Attachments:
