 1381.4 In reply to 1381.3 Hi billis - really this is a design that would be easier to do in a different program than MoI because the most simple approach is to draw your pattern in a straight line (just like your image), and then apply a kind of warp or bend transformation to it. MoI version 1.0 does not have any commands for doing those kinds of deformations. If you have Rhino, you can use Rhino v4 to do it, that would actually be the easiest way. I will create some steps to show you the next best solution that you can use inside of MoI though, I will post those in just a bit here. - Michael

 1381.6 In reply to 1381.5 One other possible way to form the design without drawing all the connecting lines is to have a start pattern like this: That is with additional lines drawn in, and the lines are extended slightly. When arrayed, it results in this pattern: Notice how the ends form a kind of "X" type crossing. Here is a larger view: When you have a set of curves like this that make a closed boundary with a bunch of little lines hanging off extra, you can use the boolean Union command on the curves to automatically trim away all the little excess lines for you and leave only the inside. So selecting all those curves and running boolean union will create this: However, it is a slightly different shaped design, all the lines are somewhat more rigid within each pattern piece. The other way of drawing connecting lines made those connection lines at a different slope which seemed a bit nicer to me. - Michael Attachments:

 About this oval I want to divide the curve ellipse AB in 5 egal parts I am not sure if this construction is right? It will be fine if a function Divide a curve exist in Moi :) There is one inside the helpers but it's just for straight lines :) (used here for draw the circles) Second image seems better :) I have used the array / curve with AB as line and AC as Path So circle's method was false And now you can draw a perfect Greca motif :) Ps can we use Array / curve as trusty tool for divide any curves?

 1381.8 In reply to 1381.7 Hi Pilou - right now the way to divide into equal segments is to draw one point object (under Draw curve / More), and snap it on to the curve. If your curve is open, place it at an end of the curve, if your curve is closed just put it anywhere directly on the curve. Then select the point, and run Transform / Array / Curve. Pick your curve as the path, and then set the Item count to be the number of segments you want. If you want to divide the curve into pieces of a specific length, enter that length as the "Distance" value here instead. Then push Done and you will have points arranged on your curve marking the different sections. Then to cut the curve, select the curve and run Edit / Trim, select the points as cutting objects, and push Done to keep all the pieces, and you will have your 5 equal sized pieces. - Michael

 1381.9 In reply to 1381.8 :) so that answer my question in the previous posted in the same time :) < Ps can we use Array / curve as trusty tool for divide any curves? but maybe an automatic tools in the V2? Add that to the wish list?

 1381.10 In reply to 1381.9 > but maybe an automatic tools in the V2? Add that to the wish list? Yup, I would like to add a Divide function that handles this more easily. Please add it to the wishlist. - Michael
