Hi Magma, you can extrude 2D curves into solids by selecting the curves and then running the Construct > Extrude command located here:



Then you can either type in the thickness you want and push enter, or also you can track the thickness using the mouse in either the 3D view or one of the side elevation views. Moving the mouse just in the same view as your 2D curves won't do anything since you're looking straight downwards along the extrusion direction there.

Hope that makes sense, let me know if you still need more details.

Hi Magma, also check out here for a video demo that has extrusion used in it as well:

There are some other good basic videos in that same series as well, collected here:

Hi Michael, thank you for your quick reply! i´ve managed to make the "fish" into an extruded object but what i can't figure out is how to make it rounder



I am tring to make this \/


look a little more like this \/


Again, thank you for your time!




I´ll take a look at those links, thanks!

Hi Magma - MoI is a CAD program and overall it's more oriented towards making mechanical type shapes and forms.

An actual fish shape (rather than just a straight-sided punched out 2D outline of a fish) is an organic and non mechanical shape.

MoI is just not really a very suitable tool for doing things like that.

It's possible to do semi rounded profiles by making a rounded capping surface and cutting with that, see some examples in these previous discussion threads:

But if you really want something that's very organic fish shaped and not some kind of stylized shape that's more suited for CAD you will probably need to use a polygon mesh or sculpting type program rather than a mechanically oriented CAD program such as MoI. Maybe check out Sculptris or Cheetah3D...

Hi again, I am aware of that. Mechanical devices was the main reason we bought MoI. However the company i work for are waiting for an update of a 3D animation software which co-operates with adobe. Until then i´m happy with MoI. (Plus it is a really exciting program to learn!)

It took some time, but the fish is now 3D and just needs a final touch, thanks to your help and the link to MOIusers blog





Thank you for your helpfulness and time!
