Hi Roger, currently MoI's blend tool is not as sophisticated as Rhino's - MoI's is only set up to blend between 2 edges and won't really handle a "chain" of edges like you need for this case.

In some cases you may be able to split up edges into matching pairs to get the job done in MoI, but really your best bet for this would be to move your object over to Rhino (you can use Copy/Paste to do this quickly), do the blend in Rhino and then bring the blend back into MoI.

It won't be unusual for you to find instances like this right now especially when you are trying to work at a "surface modeling" level of building a patchwork of individual surfaces rather than using more of the solid modeling toolset.


I do plan on enhancing the blend tool in MoI in the future to handle this case, but you should generally keep in mind that Rhino has been around for a lot longer than MoI so some of the tools in Rhino have had longer to mature.

It's still fairly early in MoI's lifetime right now, so it will not be unusual to find things like you have in this case where you need to use an alternative tool like Rhino in combination with MoI.

As time goes on and MoI gets more mature and has more things filled out in different areas (like more continuity tools and a more refined Blend tool for this case), then there will be less and less of a need for that.

But right now I'd really recommend to make use of other tools that you have available to you particularly when it's for one surface or a specific task or something like that - just Copy and Paste, get the job done, then copy and paste back into MoI.

Particularly if you're trying to do tasks that are related to building surfaces in a "patchwork" type manner and you are focused on continuity issues, that's an area that is handled better in Rhino currently.

That does not mean that you can't use MoI for your project, you can still stay in MoI for much of the work and just move things into Rhino to accomplish some specific task and then come back into MoI.

If you're working more at the solids modeling level with things like cutting objects and doing boolean operations, that is more of the area where MoI has been focused more specifically on so far, because it generally makes things happen very quickly for simple kinds of objects. In your case here you are trying to use a much different kind of modeling technique than the solids modeling toolset though.
