Hello Michael,

I'm importing and saving in a .step file. When I saved it in a .3dm file it re opened joined.
Here they are. Am I OK?

Hi Marv, yeah that's normal - 3DM format is the one you should typically use to save your model data while you are working on stuff within MoI, it's the "native" format that will keep everything in the same form as you see it in MoI. Use the other formats like STEP, IGES, or SAT only when you're trying to move your data to a different CAD program.

You may see various slight changes in things when you save to STEP and read it back in again, some things in STEP format are slightly different than how MoI itself handles things.

If you use 3DM format for your intermediate working stages it should preserve things exactly how you see them in MoI though.

Hello Michael,
Thank you. I did find importing with .step did not work well. Dimensions were wrong so I switched and imported with .iges which is fine. I now quickly save in .3dm

Here's my last and silly question.
Long1 is butted at F1 which is 3.0 wide. Firewall is 2.8 wide. How do I make Long1 fit at the firewall? presently has a .11 gap

Placing a short line segment from the notch of the firewall, forward, and another at the notch of the second cross section,
going rearward, enables a blend, with fine bulge adjustment...
Maybe re-boolean the notches to fit?

Is it an airplane or racer?

Thanks Brian,

It's an autogyro

Hi Marv, did Brian's suggestion above work ok for you or are you still stuck?

If I understand your question correctly, you're asking about making this piece shown selected here to mate up better with the circled area, is that right?



So I guess if a straight piece doesn't fit right you'll need to decide how you want a different type of shape formed that will fit, you could put in 2 rectangles and then use Construct > Loft to build a slanted surface between them something like this (shown a bit exaggerated here):



Or the way Brian is talking about is using Blend to make a kind of slightly "S" shaped transition shape, you can do that by drawing in some lines and then using Construct > Blend between the lines to generate blend curves like this:


Then you can loft between pairs of the blend curves to build surfaces.
