Hi,
I would like to do rounds to yellow edge around the part.
Couldn`t do it, so is there any way to create the round?











Thanks,

-d3-

Hi d3, the filleting mechanism in the geometry library that MoI uses is just not as sophisticated as the ones in the things like SolidWorks, SolidEdge, etc...

There are several kinds of things going on in your case here that it won't handle.

For example, the edge based filleter will not know that it should try to build a fillet between these 2 faces that do not actually share an edge:




Also it will have difficulty with things like this face being totally consumed and disappearing:




I'd recommend exporting cases like this to a different solid modeling program like SolidWorks, etc... which are able to deal with these kinds of "minimal clearance" type issues better.

MoI's one will work pretty good if it has enough space to create the fillets without needing to run over other faces though.


Otherwise if you do want to make it in MoI you would instead need to use some surface modeling tools to build it, something like trim away some areas and then build a sweep in there instead of trying to use fillet. Let me know if you want to try that and I will try to help you with it, but really if you have another solid modeling system available to you, it's easiest to export over to it and do the fillet there.

ViaCAD (http://www.punchcad.com/products/viacad2d3d.htm) is a low cost solid modeling program which can be helpful for this purpose if you want something inexpensive to help with filleting cases that MoI does not handle.

Also SpaceClaim can be good for this as well, I think you can now copy and paste objects back and forth with SpaceClaim.

I had a quick play.

I split up the faces and used Blend G1.

Hi d3, if you do want to use ViaCAD to do the fillet, export in SAT format from MoI into ViaCAD, that will probably give you the best data transfer over to there.

you can also in your case make a filet by hand (a profil +2 rails) or make a boolean merge with 2 lines and use Blend ;)
here Blend (cross over message with the Steve answer above :)

Hi Michael....

Is there any chance in the future MoI can handle this type of fillet ?
Do you have a plan to improve this area ?

Thanks :)

I guess you would want to ask the Solids++ people that question, since MoI uses their library to do the fillet calculations.

But probably putting in a fillet between faces that do not actually touch would require quite a lot of work, it's not something that I would expect to see improved in the library anytime soon.

In the future I may look into licensing some other libraries to help with this area but I don't yet have any firm plans on that.

Hi all,

Here are my results by exporting a STEP file from MoI and opening it up in TurboCAD Pro v12, adding the fillet, save as a STEP file then importing it back in to MoI:

Just out of curiosity, can you use other libraries? Like, I'm not a programmer but could you use another kernel for MoI easily, for example if Solid++ wasn't supported anymore could you just grab the Parasolid kernel or some other and plug it in?

Yeah, just make a new "Fillet" working off of the parasolids library. using it to do the solving. But parasolids = $4000.00 MoI! Maybe PunchCad licenses filleter (Or do they use ACIS)

Maybe Parasolids has some kind of licensing scheme where Michael can purchase and not have to pass a cost on to us??? (After MoI has 26 million users!)

Hi Danny, well MoI uses the Solids++ data structures for things like curves and solids, so it's not possible to just "drop in" a replacement directly.

There is an analogue in Parasolid for all the same kind of stuff, but it's kind of like how 2 vehicles may each have a carburetor in them performing the same kind of function in each vehicle, but that doesn't mean you can just swap them around because they have various different connections and mountings, etc...

Similarly when MoI needs to do something like gather a list of all faces in a solid, there will be some way to do that in both Solids++ and Parasolid but it may be named slightly different, maybe puts them into some different kind of array type, stuff like that.

So there would be a fair amount of porting work involved to completely switch.


But a more localized switch just for one focused area, say like filleting and shelling, would be a lot more feasible I think.

Hi Burr, Punch / ViaCAD uses ACIS.

I'm not really sure if it is possible to have Parasolid in something under $2000.

But I think ACIS could be more feasible.

Well Michael, after MoI v4 or so, you could take 2 years and write a killer fillet'r, then license it to parasolids as a better one than they have!!!! oooppfffff!

Hi Burr, well to make a really good filleter involves recognizing and handling a lot of special cases. It's not really something that works with only a single universal code path.

It's probably more like 10 year job to make a very good one.

In ten years I'm hoping to model in holographic view like Robert Downey Jr. in this clip.

Just be careful about getting carpal tunnel syndrome from waving your arms around all day long! :)

Hi Michael....

How about Rhino, can I create the fillet in Rhino ?
What kind of geometry library behind Rhino ?
