recreating a rounded pyramid in moi. 1-9  10-29  30-39

 1782.10 In reply to 1782.8 Hey, Yes, I used the sweep method since that was the only way to reproduce the shape I wanted. I didn't use two joined curves however. What I did was draw a single line, add a point in the center and drag it down dead center to create the curvature of the base spline. I copied and rotated that and constructed the solid with sweep. An example would be very helpful. Thank you for your time.

 1782.11 In reply to 1782.10 here's the spline curve I used. In this case i'm not sure how I would maintain the curvature while deleting center points. Attachments:

 1782.12 In reply to 1782.10 Hi telnoi, I've attached a sample here, with this set up as larger surface sheets it will make the filleter a lot happier, you should then be able to select the edges of this one and fillet it. - Michael Attachments:

 1782.13 In reply to 1782.12 thank you, I still have to get used to the idea that points in certain places will create more edges :(

 1782.15 In reply to 1782.13 Hi telnoi, > thank you, I still have to get used to the idea that points in certain > places will create more edges :( It's not so much the points themselves (unless you used Add Pt with the "Make corner point" option), it is when you use Edit/Join to glue 2 segments together into one composite curve object. With that curve being made up of 2 segments, many things will process it in a segment-by-segment basis, same thing as if you had a rectangle made up of 4 segments and extruded it, you will get edges at the ends of the line segments making up the rectangle. The same basic thing is happening here due to the segmentation even though the shapes are smooth to one another. It could be possible for me to automatically fuse segments together in cases like this that have smooth pieces to one another, but unfortunately although that would have been better for this particular case, it tends to cause problems in a lot of other cases for mechanical objects, I was describing that some in this previous post here. So to avoid those problems it tends to make things lean more towards segment-by-segment processing. I definitely want to make some better tools for making single segment symmetrical stuff like this easier though. - Michael

 1782.16 In reply to 1782.15 > I definitely want to make some better tools for making single segment symmetrical stuff like this easier though That would most certainly be welcome. However, learning to construct models correctly in the first place seems to be a better learning method ;). One last question related to this shape. Would it be possible to construct a base shape which would allow the construction of a 4 sided pyramid? In this case, the base needs 3 edges instead of 4, complicating the matter somewhat. The curvature of the base shape is correct, but the amount of edges is not. EDIT: never mind, managed to figure it out by intersecting a sphere with the old shape and using that base to construct the entire pyramid.

 1782.17 In reply to 1782.16 Hi telnoi, You look like you are making it difficult for yourself. Pilou put you on the right track by showing you to use the rail revolve, but, I do not think the intention was for you to produce the shape shown and then attempt to fillet. If you progress from what was shown, you can produce both pyramids with a rail revolve without a need to fillet etc. EDITED: 3 Aug 2009 by MANZ

 1782.18 In reply to 1782.17 Hi Manz, Is your bottom rounded also or flat? If rounded, how do you get it with reail R.

 From: telnoi 16 Jul 2008  (19 of 39)
 1782.19 In reply to 1782.17 rail revolve couldn't be used to create the shape i needed, since the rail itself would have to be curved too ;) So far, curved rails did not produce the result I was after. Thanks for the tip though, it's appreciated.

 1782.20 In reply to 1782.19 >>since the rail itself would have to be curved too ;) Both rail and profile are curved in the example I have posted. I also attached the 3dm file. Are you saying the shape I posted is not what you wanted? If not, then just edit the profile and/or rail.

 1782.21 In reply to 1782.18 >>Is your bottom rounded also or flat? If rounded, how do you get it with reail R Just download the attached 3dm in that post. The rail and profile are in that file.

 this is the shape I was after. Attachments:

 This is basically the last issue I'm facing prior to finishing my model. I am again havving issues with a pyramid shape. The shape on the left was done using rail revolve, the shape on the right with lofting. The issue here is that both shapes have undesirable fillets. The picture explains the issues. How can this be avoided? I have also tried just lofting two triangles that are not rounded, after which I applied a fillet, but that also seems to result in overlapping fillet edges. Attachments:

 Pilou, that is what I did initially, but I required more control over the final outcome of the fillet shape itself. The client i am working for is very specific about these kind of details. >And ran Construct / Blend to create a blend surface between them: First time I used those tools :) seems they may come in handy fixing some other minor issues I was facing in the past. I am most certainly looking forward to the v2 update. Moi is such is a useful product, especially considering I learned to pick it up and do some decent work within two days. The final model would have been absolute hell to model in c4d, or any poly modeler for that matter.

 1782.29 In reply to 1782.25 Hi Vincent, > Ou la la, There is much simpler!! Definitely that is a more simple way! But all those rounds that you show there are of the same radius, it's a different shape than having a larger sized round towards the front and smaller rounding around the long parts. - Michael
