Step 4: Combine Through Intersection

Lofting in 123D can be very simple.  I first was very confused because the program thought that my sketch was a path.  If you see a starburst like icon next to your sketch and it has anything other than **profile** in the text box, then click the star and select swap.  Then everything should work just fine.  Don't forget to use the OK operation to complete the Loft.

I'll show exactly what the sequence should look like in the "What Not To Do" step, but if you understand the Combine operation, then you can jump right in.
<p>Sorry for the reviving an old instruction, but wondering if it would be possible to update this with current tools. 123D seems to be lacking some of these features now - wondering how to do this in 3dmax or fusion 360 (or other)?</p>
hmm. As I currently use Fusion 360 almost exclusively, that seems like a good idea. Is this for something specific you are trying to do? I've made other items since then and have discovered a few more details that impact success, but I don't know that I can commit tremendous time to another instructable right now. Could interact with you directly in the meantime though. Would make for a better instructable in the future that ways as well.<br><br>see attached images for a puzzle I made for someone. when the blocks are not rotated or placed on the wrong posts, the shadow is garbled. Here it shows 825. The &quot;simple&quot; blocks are disguised and tricky to predict the shadow when looking at them individually.
<p>Yes - I'm working on a particular project that I think this technique could dramatically simplify. I'd greatly welcome any guidance you may be able to offer - my email is my username at gmail.</p><p>thank you!</p>
What material would you use to print this? Does it need to be a black plastic, or would an opaque white work as well?
I think they used Objet VeroWhitePlus FullCure835 on my other instructable, which is not&Acirc;€&Acirc;™ black. It <em>is</em> opaque though.<br>
Very cool idea. Well done!
What a good idea.
