hello moiers,looking for some help.how do i draw a wing? what i have so far is a rectangle drawn in 3d view and 4 elipes.i havethe rectrangle drawn in a solid,the elipses drawn in freeform spaced down the y axis.how do i connect every thing together? can someone give me a 1-2-3 step of events? i have been trying to do this for several days and i just haven't had any luck with it. i a newbee to 3-d drawing. what i have done so far has impressed me with this program. now, if i could just get it to do what i want it to do. any help would be appreciated.

Thank you, Chuck

Hi Chuck, can you please post the .3dm model file with your rectangle and ellipses in it?

It will be a lot easier to understand what you are trying to do by looking at that model file instead of from your text description alone.

Also if you have any kind of rudimentary 2d sketch drawing of what you want the wing to look like, it would also help a lot if you could post that as well.


Otherwise, my best guess is that you would want to select all the ellipses, then run the Construct / Loft command to create a surface that passes through them.

thanks for the reply. idid that all iget is a blob of mjglkjbkj.i saved the file as .stl opended in cut 3d and up came a rectangle with a mass protruding from it . no depth. except for the rectrangle.??

heres a crude sketch

Hi Chuck, can you please also post your .3dm file with your ellipses and rectangles in it?

You can also e-mail it to me at moi@moi3d.com if you want.

I am at a loss at what you are attempting to create--and the drawing does not help I don't think.
Are you trying to create some thing like a (windmill?) fan or propellor (as the attached)?

hi, it is a single blade;airfoil.basicly a tube hooked to a box.

Hi Chuck, from what I understand here is the best that I can recommend for a step-by-step:

If you have a set of ellipses like this:



Select them all:



Then run Construct / Loft to create a surface through them.




If you are getting something substantially different from what I show above, it would really help if you could post your .3dm model file so I could see what might be going on in your particular case.

One thing is that if you are selecting the ellipses by clicking on them, make sure to click on them in the sequence that you want them lofted in. Like for example don't click on the middle one first, then a couple on one side, then a couple on the other side, instead click on them from left to right order so that when they are lofted in that order you will get a proper result.

If you select them with an area select (by clicking off to the side in empty space and dragging a selection rectangle), or by something like Select All, then MoI will do an automatic sort of them. If your curves are all at odd angles to one another the automatic sort may not work completely right and you may need to select them by individual clicks instead in that case.

yes ,thats what iam trying to do!! now i would like to add a rectangle to the end of what you have drawn,only one end.
thanks for you on going help, chuck

michael,my lofting has black lines connecting the elipes and the elipes are in black with a lite grey shading different from your lofting? yours has no black lines and the shading is brite .

Hi Chuck, I'm entirely sure if this is what you mean, but if you want to have a box on one side, you can create it by this method.

Start by running the Draw solid / Box command, located here:



Place the first 2 points something like this:



And the 3rd point for the height something like this:



Then in this case I went to the Front view and dragged the box downwards a bit, to result in this:



Now you can fuse those 2 pieces together by selecting them both and running Construct / Boolean / Union.

Can you please take a screenshot and post that here? You can do that by pressing the "Print screen" key on your keyboard which will take a snapshot of the screen and put it into the clipboard.

Then you can go to an image editing program (Windows paintbrush will do if you don't have anything else), and paste that in and save as a .jpg file, and then attach that here (or e-mail to me at moi@moi3d.com).

It is really hard to understand what you are seeing just from a description, a screenshot will make it much easier for me to understand.

Also, if you can post your .3dm model file that would also help as well.

One difference in what I showed was that I deleted the Ellipse curves after I completed the loft, so that you could more easily see the generated surface.

In this exercise I made the two squares and the rounds.
Firstly I lofted the two squares, then lofted a second time as shown.
Was that if interest?

Hope this is not out of place, just experimenting a bit with the concepts inspired by the thread.
