Extruding with an angle....

 Hello, a new question: Moi can make extrusion with a angle? See image attached! :) Tnx in advance for the reply! P.S. I know that is possible to make this with a sweep, but into my project have a complex section (not arectangle!) ! :) ___________________________________ MrBraun - Moderator www.C4dHotline.it www.MrBraun.altervista.org Image Attachments:

 3228.2 In reply to 3228.1 Hi MrBraun, MoI does not yet have a tapered extrusion function. But you can probably get the result you need by doing a combination of Offset, then moving the offset result in the Z direction, and then Loft. Those are actually the same steps that a tapered extrusion would do internally. Please see this previous post for an example: http://moi3d.com/forum/index.php?webtag=MOI&msg=941.5 If you have any difficulty with your particular shape, could you please post the curves so I could take a look? - Michael

 Another solution :) (the 2 lines are of course drawn with the Helper lines for have Tangencency ;) Not so a big deal ;) ps Else this function exist in Google Sketchup ;) Smartpushpull ;) http://forums.sketchucation.com/viewtopic.php?f=323&t=23341 With the Michael's solution you must calculate the height before and the wight of offset ;) EDITED: 7 Jan 2010 by PILOU Attachments:

 3228.4 In reply to 3228.3 Hi Pilou, that's an interesting solution! But just keep in mind that offset and scale are not equivalent - offset will keep an even distance between 2 shapes, which can often involve changing the proportion of different internal segments. For example if you have a curve like this: Then offset will produce a result like this: Notice how it is much differently shaped than just a uniform scaling of the original shape? This is why you usually want to use offset and not just simple scaling in order to maintain an even "wall thickness" between pieces. The only way that scaling gives you the same result is in some special symmetrical cases like a circle. - Michael

 3228.5 In reply to 3228.4 Yes Scaling is homothetic (when x,y,z), Offset not ;) So maybe Offset with my pyramydal concave convex form don't work due the different incline angles ;) EDITED: 7 Jan 2010 by PILOU
