It's not possible to have just a list of generic "pre calculated" curves?
And we can modifiy it on the screen with the normal function, Scale, etc...
So no need to implement a complex formula inbox :)
Sorry for the 24 hours, I can't make nothing, I am not the creator of this curious world :)

But do you really need a command for this? From what you're describing there just importing an .igs or .3dm file with those curves in it would work the same way.

One thing you might try: http://www.graphcalc.com/index.shtml I saw some people mention it can export to DXF. Maybe it is possible to convert to MoI through Amapi. If you have a few that you want to convert, you can post them here and I can convert them from DXF for you using Rhino too...

Not a command :) Just a little "library"
Of course any curves or surfaces can be imported in moi
just seems more cozy to draw all inside Moi :)
Sure I can draw easily a sinusoid with just 2 arcs and arraydir :)

I guess it seems like a repository of files is pretty much the same thing as a library to me...

But this isn't a very accurate sine curve - a "real" sine curve doesn't have the shape of an arc. Which is kind of funny since it is the graph of an arc as it swings around...

an arc of an half circle of course
Ps For the progs : ) http://forum.jotero.com/viewforum.php?f=24

K3Dsurf seems the best It has an OBJ export
Rest to found a transform obj -->nurbs That is another story :)

Yup, but although it is similar, it is not the correct shape. A sine curve is kind of more of a lump, it doesn't have the exact shape of an arc.

This may be a difficult transform. But didn't Amapi do something for this when exporting polygons to IGES? I thought that some wireframe line curves came through. So that is one possibility.

But it looks like K3Dsurf only does surfaces and not curves - for doing curves possibly that other one will work.

Half circle and Scaled on 1 or 2 directions successively with subtil axes of deformations :)

PS Yes Amapi has Iges , and Rhino has a plug named Smurf I believe

And you can draw in k3Dsurf curves just take the good parameters for have a slicy slice :)
And export it as OBJ : that works (Button is named "Edit" but It's also save ! :)
Sure it's a pity to not profit of the Surfaces :) :I don't want to be the triangles of this curve :D

Hi Michael,

I'm just wondering if it's at all possible to have Height & Width with the Draw Curve > Eclipse > Centre.
So that it would work like you've already got with the Draw Curve > Rectangle > Centre.

From a Jewellers perspective, this would make life much easier than having to count the grid spaces when creating an oval.

regards Colin

Hi Colin, I'll try to add that in.

In the meantime, you can use "Distance constraint" to help out right now.

To do this, just type in your distance and hit enter (you can also click on the "d" text box down on the bottom bar).

Doing that activates distance constraint which forces the point that is being picked to be that distance away from the base point. So for Ellipse/Center that would be 1/2 the width since the base point is the ellipse center point in that case. So you would actually need to enter in half of your desired full width for this one. Still easier than counting grid spaces though.

But I'll try to add in a width/height like rectangle so you won't have to divide in half.

Hi Michael,

Thanks for that advice, I'll give it a try.
So far I've been getting around it by creating a Rectangle the exact size I want.
Then I just select the Eclipse & have it snap to that Rectangle edges.
Delete the Rectangle & continue from there.

regards Colin

Hi Colin, I've added a Width and Height control for the ellipse command for the next beta. You still need to click 3 points to finish the ellipse even if you enter a width and height, because those points define the orientation of the ellipse. In 2D the 3rd point doesn't really do anything if you have entered a height, but in 3D you can switch to the front viewport (or track along a z line in the 3D view) to orient the ellipse vertically.

This was the last thing I wanted to fix up for this beta so it is almost ready.

Move a "hole" or fill a "hole"
but maybe is some hard work ? :)

Hi Pilou, one way to fill a hole is to remove surface trims.

Here are some steps on how to do that - this shows the steps for removing a hole in a cube:
http://moi3d.com/forum/index.php?webtag=MOI&msg=444.4

Here is a longer tutorial about removing holes on a more complex object:
http://moi3d.com/forum/index.php?webtag=MOI&msg=446.17


There will probably be another "fill in hole" tool at some point called N-Sided Patch. I might be able to do this one soon, I'm not quite sure yet.


Moving a hole can be pretty difficult, especially if there is stuff attached to it. It will be quite a while before I'll be able to work on this one, although probably this will get better with more history support, if you could control the history of how the hole was originally created. There should be more stuff for that in V2.

- Michael

beautifull soft, for me, a dwg or dxf import (2d at least) would be a great enhancement...

great job!

Would it be possible to have a Bend along curve option. It would go well with your new boolean curves to form shoe treads, tires and stuff like that.

Hi Pilou, I've got this one on my list (defining mirror plane by 3 points), but I don't think I'm going to be able to get to it for V1. I should be able to get it for V2 though.

Hi tmaes, thanks I'm glad you like it! I would like to add DXF/DWG support in the future, but it will take kind of a chunk of work to do it so I have had to postpone it from the 1.0 version.
