Hi shayne,

> How about a 2 distance fillet as in the chamfer command

How would you want the fillet to be formed? I don't think it is possible to put in a circular cross-section in between 2 different radius values.

See here for some previous discussion on this:

What I mean is apply a fillet to an edge but have 2 measurement distances available
Then I guess you would need a way to control the bulge of the curce also




To cut the above variable distance fillet to a curved object gets very difficult

thanks

Hi shayne - it looks like in your example there you've got an ellipse for the rounded shape?

That works great for something that meets at a 90 degree angle like that particular case you are showing there, but I'm not sure how it would work in the more general case of surfaces that meet at other angles to each other.

See here for a description of that problem:
http://moi3d.com/forum/index.php?webtag=MOI&msg=2259.12

Also since it's kind of unusual as far as these things go, as far as I know the geometry library that I use to calculate the fillets does not support that style of fillet creation - another thing that's a lot more difficult than just the simple case you are showing there is when multiple fillets collide into each other and corner patch pieces need to be calculated to glue them together smoothly.

So I mean I guess it could be possible to make a special fillet that only worked when filleting just one edge of a box like you are showing there, because that special case happens to avoid these various issues, but then that would probably confuse a lot of people when they tried to use it in a whole bunch of other non-box situations and it didn't work properly on anything else other than a box...

Thanks Michael
I understand the complexity now

How about a bend command






The yellow centre twisted solid can it be deformed to bend or follow the profile curve next to it ?

ps love the twist command

I notice on http://moi3d.com/wiki/Wishlist that the above requests already feature

Ok I'm dumb , figured out how to use the flow command :)

thanks
shayne

Hi shayne,

> The yellow centre twisted solid can it be deformed to
> bend or follow the profile curve next to it ?

Yup, you can use the other new tool in V3 "Flow" to do that kind of bending.

Flow allows you to deform an object from one "backbone" curve to a new backbone. You've actually got this all set up in your file already, the base backbone will be the line running down the middle of the twisted object and the target backbone is the curve off to the side that you want it to follow.

To produce the bend, select your twisted object, then run Transform > Deform > Flow (it's right next to Twist), then select the center line as the base curve, and the bent one as the target curve and you'll get this result:




By default curve-to-curve flow will preserve the current length of the object, mapping distance traveled along the base curve into distance traveled along the target one, with the overall length of the object being unchanged. There's another mode you can activate by using the "Stretch" checkbox option in curve-to-curve flow which will instead map percentage traveled along the base to percentage along the target instead.

If you wanted to make the twisted object take up the full length of the bent part, you would shorten the base line a bit so that it was flush with the ends of your object and then use Stretch mode.

EDIT: Ok it looks like you got Flow handled already...

- Michael

And re: Bend - right now I don't think that there will be a separate Bend command, since you can already use Flow to do bending if you just use an arc as the target curve, and it's also far more flexible since you can use any kind of curve you want for the target shape.

Michael,

I would really like something to be able to group objects together and handle them as a unit. I understand this can become quite complex but I'd be happy even with something relatively simple.

I suppose that ideally a "group" would allow for a group of groups where each individual object and subgroup keeps it's properties. A named group, say a "door" with all of its parts could be tagged as the left, right or whatever "door" and not necessarly become a distinct object. A mechanism to distinguish type of "copies" of a group, say a "cloned group" would be an exact duplicate of the original this would allow the possiblility of editing individual part of a group and update all "cloned group" automatically. Another type of group could be allowed such that edits are not updated automatically but on demand, here I'm thinking of my left and right door again which may not be 100% symmetrical, say for example that the right door as an additional part that serve as a stopper for the left door but beside that part every thing else is symmetrical so edits could apply only to corresponding parts in those groups. Say for these doors again, this time not only the right door as an additional part but some parts are could be distinguish further like say a left and a right hinge and of course at this time we could setup a different style to the hardware parts of the door such that it's easier apply the proper material later on. One last thing I'm thinking of for my ideal doors "groups" again, it would be something like tagging individual part in somekind of hiearchy say

door.right -> right-hinge.001.brass or right-hinge.top.brass
right-hinge.002.brass or right-hinge.middle.brass
right-hinge.003.brass or right-hinge.bottom.brass
crossmember. top.002.walnut *** this part is a mirrored copy of door.left -> crossmember.top.001.walnut
...
panel.top.002.walnut *** this part is a mirrored copy of door.left -> door.top.001.walnut
...
etc.

Then of course, some means to create a bill of material for these doors. This could go on and on but as I said earlier, this would be the "ideal" group thing for me, maybe in another life.

For now I'd be happy with a much simpler grouping mechanism that would be useful both in Moi and on mesh exports.

Thanks,
Felix

Hi Felix,

This is something that's called "instances" and it's usually a separate mechanism from a "group".

I do want to have instances eventually as well, but I think that it will be a different mechanism than groups - what I'll be trying to do with groups will be more of how they are typically done in other software, just sort of a way to cluster objects together as another organization method, not as a way to maintain a master definition and instance clones.

I do expect to be able to have nested groups though, and if you have a group within a group it will show up as a hierarchy that you can expand in the scene browser, so you could hide the whole group if you wanted, or you could expand the group and go in and only hide some sub-groups of it or whatever. So it will be a way to use it to make a hierarchical organization to your objects with parent/child containers instead of just a flat list of names like object names does now. Then the other part is there will be an option for if you want the group to select as one unit when you click on it.

Maintaining instances and updating them when a base definition changes is a whole different thing than that though. I do want to have that as well at some point but I do not expect to have instances done at the same time as groups, they are different things to work on.

Michael,

your idea of group and nested group selectable as a unit is fine with me. Would this mechanism allow for different styles to be used as well? I assume it will but I just want to make sure. At render time this would be very useful.

Thanks,
Felix

Yeah it should be a separate thing from styles. You might need to do something like set the styles before you make the group, or temporarily turn off atomic selection of the group in order to select different individual objects within the group to assign different styles to. I'm not sure yet how a "drill in" type selection might work.

A real "Strecht" function ? (no need to trim / split for avoid deformation who arrive with scale )

IsoCurves with a U and a V value input for frequency and the ability to edit/move them... Thats 4 for me (Less the beer thing).. One to go!

Thought I would finally add my top 5 to wish list:

1.) Deform face feature - similar to NX I-Form, X-Form or Pro-E WF Warp/Sculpt features.

2.) Draft/taper face feature.

3.) Volume and area analysis toolsets.

4.) Parasolid import/export.

5.) DXF (and/or) DWG import.

Not asking much am I? :-)

Hey, I remember this thread...


pssst::: (super blend tool) ;-) you didn't hear that from me.

Michael T: I think you would find the price of MOI going a lot higher if it it had Parasolid import capabilities. I recall Luxology mentioning that they had to pay a high licence fee to Parasolid to create their CAD importer. It was worthwhile for them because of their link with Dassault and Solidworks. They had a clear market to aim at. But that is taking Parasolid nurbs data into a polygon app. In the case of MoI you would just be substituting one Nurbs format for another, at quite a high price.

Hi SteveMacc,

Actually the Parasolid import/export request should have been placed last on my list. Could live without that one, plus there are other translators for it.

Good info to know about Luxology and the costing/license issues.

And finally number 5.. Extend surface tool.. This can be seen in a video here:

http://youtu.be/tv40aawZAY4

You can go straight to 30 seconds in to spare yourself the entire video.

Basially extending a surface continuing the edges curvature. Could be great for patch modeling.

I'll get my own beer, thanks!

As a side note, he has done a good job with his blend command in relation to what I was describing in my previous request about blend bulge. Hes has those options and a couple others.. He also has the UV thing I was just speaking about (Although not IsoCurves. I think he's rebuilding the surfaces) The video shows this just after the extend surface part...

Good luck Michael with your V3 work and future release!

Cool tut about tangency!

What is this seam problem? Haven´t seen it in MoI.
