Doing a Rhino tutorial in MoI and hit a snag.

Has anyone ever tried this tutorial in MoI

http://www.rhino3dhelp.com/tutorials/learn-how-to-model-a-bottle/

I have gotten to page 2 where I am trimming the unwanted parts of the surface. After sweeping and trimming the main cylinder I don't know how to trim the balance of the sweep to keep only the part that would cover the hole.

Any ideas?

Hi Don, could you please also post the 3DM model file of the objects that you are showing in your screenshots? That always helps to be able to use your particular model file to help answer a question.

Hi Don,

Normally I would use each surface to trim the other, so that will give a good result for joining. Having a quick look at your model there appears to be a slight problem with broken edges.

If you look at the area highlighted(I have removed the cover in this pic)




You will see where edges do not join, also on this side shown, there is an extra little face.




Trying to use that edge directly for trimming can give further problems. So what I suggest, is to select all the edges around that opening(make sure you select them all, as there are 2 little edges(one each side) near to where I highlighted the problem edges)




Once selected, use "Extrude"(with option:- both sides) and extrude that edge into a surface




You can then use the extruded surface to trim the cover.





- Steve


edit.
Sorry, for some reason I made my reply to Bob.

Hi Don, yes like Steve mentions above normally you would want to trim 2 things like that with each object cutting the other.

It can be a good idea to do the trimming of things like that all in one go, which is called a "mutual trim". That's where you have some objects being trimmed where each object is both a part being cut up and also acting as a cutting object at the same time.

That looks something like this - if you start with 2 objects that are crossing through each other:



Now select both of these pieces. That will look like this:



Now run the Edit > Trim command. The trim command will see both those selected surfaces and know that those are parts that will be cut. It will then show you a prompt in the upper right area of the window that says this:



So note there that it says that you can select some cutting objects or you can push Done instead to do a mutual trim - you want to do a mutual trim in this case so instead of picking any cutting pieces you just push Done right now (or right click in a viewport which is a shortcut for pushing Done) without selecting anything else and that tells Trim to use each piece as both an object to be trimmed as well as a cutting object.

Then it will slice it up and let you pick which parts you want to discard (you can right-click on this stage instead of selecting anything if you just want to slice it up and have all the pieces). So in this case you would select these 2 fragments here:



Then when you push Done or Right-click to finish that last stage of the Trim command this will be the result:

Thanks Michael & Steve.

I haven't had a chance to work through your suggestions yet, but hopefully sometime today I will. I just wanted to say thanks and I will let you know how I make out with it when I can.

I had a chance to complete the model so am posting a finished render.

After completion in MoI, I saved to stp format and opened in TurboCAD where I applied materials, including the label, which I made in Photoshop. I then rendered and saved in jpg format.

You have a great product Michael. I am glad that I happened across it and decided to give it a whirl. I am pretty sure I will purchase it when my trial nears completion.
