You see iso curves only when you draw them or when thare drawn!

Else you have the Multi-iso http://moi3d.com/forum/index.php?webtag=MOI&msg=6841.14

Hi RJ,

The Iso command is along-side the Project and
Silhouette commands:

Construct>Curve>Iso (u or v or both can be selected)

There may be better ways than my remarks.
Others will chime in when the time zones align:-)

Hi Rj, nice model!

you can easily fix the surface continuity at the join by Trimming a bit from each side and filling the gap using Blend G2.

Hi RJ!

If you divided your model in half and you get this result after mirroring, then it might be the case that your initial model was not completely symmetrical to begin with, or it would have this groove as well. Is that a SubDivision surface import or you modeled it inside MoI?

ps. Your model resembles a duck skull, it's cool :D

THX a lot Pilou!!

THX Bemfarmer for your help!!

Hey Dinos! This is a very good idea!! THX for your help - I appreciate that very much!!

hahahaha... duck skull :-) :-) - you are right. Yes, maybe it had already this groove. No, I have modeled it complete in MOI3D - I come from poly-modelling within c4d - 7 years now and it took (still take) some rethinking about modelling - but overall I love this method much more over polymodelling - the best would be to have both in Moi3d :-) ...

You can yet make funny spaceSphips in a minute like poly/ subD moding inside MOi! ;)

Take a look at this marvelous thread! ! :)

Of course you can complexify ...it's just 10 seconds scribling...
