The downloadable code is nearly all Javascript. Basic and very pretty javascript code running on a Canvas. Did not see much physics.
Did not see any licensing information.
PhET has simulation software, but only for Teachers. Seems to be free, with many packages. Hard to tell what it could be used for.
Saw their statement that for $100,000 they will work on a new package.
Working Model 2D looked professional, and pricey, with annual fees.
And while doing other searches, encountered some malware of some short. Seem to be pushing antivirus with popups. Hard to tell these days.

A very fun & easy 2D free simulator (a true gem) : Algodoo ;) But you must all build! ;) http://www.algodoo.com
I can answer to some questions about it! :) (only direct first level - not scripts! ;)
I would like to see shortcuts tool tip on hover over tools, sometimes I forget them and also to check that the shortcut isn't in use, I am daft enough set one twice.
Not sure how practicle it would be but it would be cool, for new users in particular.
Hi Mark, the way MoI is set up there are very few shortcuts defined by default, just very standard ones for stuff like New, Open, Save, Delete, Undo/Redo.
Then you can set ones you want for things that you use frequently. If you're not using it frequently enough to remember it then probably you don't need to have that shortcut and should just use the button instead.
Thanks Michael,
Yes I understand that.
I set a lot of the them and remember most, but swapping between apps and not using Moi for a while seems to be the thing for me.
Anyway just a suggestion, all the best with the new beta.
Is there a reason that View > Image > Add places the image on the active cplane, but make2D and File > Import place on the x-y plane of world coordinates regardless of the active cplane?

I guess the main reason is that View > Image > Add is an interactive drawing command where you pick inside a specific viewport with the mouse and so at that point it picks up not just the active cplane but also a particular view.
Neither Make2D nor File > Import involve picking a point so the difference stems primarily from that.
For import if you right click on the File > Import button it will launch the "ImportPart" command instead of regular Import and ImportPart lets you pick a placement and orientation of the imported object so that will adapt to the current cplane.
I use MOI for fixing a lot of geometry outside of a CAD system. I like the way it functions etc. I've dabbled in rhino and considered buying it, but it does have an awesome feature where you draw a grid out and it projects it onto the surface and gives you a fresh clean surface. I suppose it's a little like projecting curves onto a surface and then using a sweep or whatever, but it cuts out the faffing with rebuilding afterwards.
I know nothing about programming and also not trying to compare the two programs. I may be well off the mark here, might be something that no one uses I don't know. Just throwing it out there :-)
Hi Chris, I think you're asking about the "Drape" command in Rhino?
That method doesn't really give very good quality results, there is usually a lot of "stair stepping" kind of artifacts.
For that type of surface reconstruction it would probably be a lot better to convert to polygons, then use a polygon retopology tool to generate quad polygons over it and then bring that back in to MoI using the SubD converter. That would give you a lot more predictable quality than drape.
HI, would it be possible to "save" a specific view? It would be great for the ones of us who export 3d views for illustration purpouse. I found it difficult to edit my 3d geometry and use the same 3d view again for the export. Saving and locking a specific view would be great.
Looking forward to v5, such a great tool for a technical illustrator! :-)
Something like ViewManager would indeed be nice. Perhaps together with a posibility to numerically change the view. I like the control in Teamcenter visualisation.
In snapshot, it’d be cool to have an indication of what slot is in use? And maybe possibility to name them, name showing up like a tooltip or somthing. Also is it doable to have it remember what objects are visible and hidden?

There are currently some numeric controls for view angles under Options > View > 3D View angles.

That snapshot function isn't a regular part of MoI, it's from Max Smirnov's CustomUI mod. I don't think he's developing it any further though.
In the future I do want to work on some kind of save/restore state mechanism though.
1) A way to get the point at the center of an object. That is, the point that's shown when Object Snap > Center is on. In other words, something along the lines of propertiesPanel.radius. This is for changing the UV directions of a spherical face for hatching.
2) Harmonize the 5 bounding box methods by adding an optional coordinate frame parameter that defaults to the active cplane. Now, the properties panel bounding boxes are aligned with the cplane, but the others are aligned with world coordinates:
GeomObject.getBoundingBox()
ObjectList.getBoundingBox()
ObjectList.getHighAccuracyBoundingBox()

There isn't an object snap for the center of a face that is a sphere surface. The one that you get on a regular sphere comes from the center point of its arc edge curve.
I'll see about adding in some script access for conic sections on faces similar to what there is for curves though, and about adding in a coordinate frame optional parameter for bounding boxes.
I noticed center snapping on a full sphere, 1/4, and 1/8, and that propertiesPanel.hasRadius seems to be true for any fragment of a sphere, but I guess those are special cases. Thanks for explaining that the center snap point is coming from trim curves.
re:
> adding in some script access for conic sections on faces
I don't understand what this means. To me a conic section means a curve.
The problem I'm trying to solve is getting the UV directions on a spherical face to go in the directions that I want. My plan was select the face, get the radius and center, cache the trim curves of the original face, generate a sphere with the same radius and center but with seam orientation picked with something like an orientation picker, remove the original face, trim this new sphere with the cached trim curves, and then join.
I guess I could draw 2 pointObjects snapped to the surface of the face, dropPoint to get uv coordinate points, evaluate normal at each of the uv points, extend a line along each normal, and find the intersection = center. Is that the best way?
