Booleans Part 2:
Rhino for Mac is exciting and it’s … here!
We’re making and publishing some Rhino for Mac tutorials and we’re starting with the basics to introduce the software to those of you who may be completely new to it. Rhino is a great tool and we hope these tutorials will be a helpful starting point in your journey with the software. In this tutorial we continue our look at some of Rhino’s Boolean commands, namely: Union; Difference; Intersection; Boolean two objects. This tutorial is presented by Sean, one of our Rhino3d trainers.
We’ll be publishing new tutorials as regularly as possible and if you subscribe to this channel you’ll be the first to know about them. We’ll be introducing some more advanced tutorials too, for those of you who already know the software but would like to see some cool stuff! Let us know what you think and of course let us know what you’d like a Rhino for Mac tutorial to cover and we’ll see what we can do.
Thanks for joining us from all at the Simply Rhino team.
hi this is Sean from simply rhino welcome to today's tutorial in which we'll continue with our series in order to help you learning rhino for mac in this tutorial I'm going to be looking further at some boolean commands okay now let's start by just creating a box so I'm going to slide up to solid box corner to corner I've got grid snap on I'm just going to make a couple of left clicks here in the top view to define the base and then I'm going to define a height by just dropping down into the front view here my cursor now let's change the type of view that I have here – a ghost in view and I'm gonna place a sphere on the corner here so I'm going to slide up to solid sphere Center radius make sure that I've got my my end object snap on here so I make a left click then I slide down to the front view here and snapping to the grid placing my radius at about nine o'clock there for the seam of that sphere will be placed in a fog '''l location now I'd like to just start by just expand that perspective by showing you this particular command okay boolean two objects obviously the limitation on this command is that it will only work with two objects so if I just execute that now top left hand corner Ron is asking me to select two objects – boolean and note that the boolean sorry the delete input is ticked here I select one object and another now right-oh asks me to click to iterate through boolean results press ENTER to accept what that means is that if I make a series of left clicks Rhino is going to cycle through the boolean possibilities and you'll see in the bottom left-hand corner here of the interface intersection okay Serrano's reporting to me what type of boolean I'm viewing here so I'll make another left click bottom left-hand corner a minus B okay so that that's the difference is if I was using the boolean difference command I'll make another left click that's another difference but it's the part that's been removed from the sphere I'll make another left click inverse intersection that's interesting because that particular one isn't available from the drop down menu I'll just cycle through I've got a union intersection a minus B B minus a inverse selection okay that's probably the most interesting one so I'm going to just press ENTER now and it's gonna be this would have left me with the inverse selection this so let's just see what that is an inverse selection I just drag this object away and you'll see it's removed the intersecting part between those two objects now what I would like to do now is I'm just gonna type in confirm straight commands it and again okay so I'm going back to my two original intersecting objects now I mentioned in the last video that it's of benefit if we try to carry out boolean's without directly using the boolean commands so what I'd like to do is to show you a few examples of precisely that so I'm going to select those two objects and using my oops my gumball here I'm going to just make a few copies so what I'm doing is I'm holding down the Alt key that's gonna make a copy and again I'm gonna hold you down the Alt key and I'm just dragging that constraining red arrow direction right okay so just as a repeat of previous I'm going to use my so this is a reminder I'm going to come down to curve from objects and I'm going to choose intersection so one two I press ENTER now that's left me weird take gone ball off its left me with a closed curve and as we saw previously we can use that particular curve to carry out a what would have been a boolean difference command by using the trim command so if I click on the edge of the cube here and then the top of the sphere all that leaves me with is to join these two objects together so now I click on join okay so that was carrying out what would perhaps have been a boolean difference but using the intersection command followed by trim and join now let's see how we can carry out something similar here but simply using the split command so if I execute the split command rise can't run is gonna ask me select objects the split I choose the sphere as the object to split i press enter it asks me for the cutting object I choose the sphere I press enter now what I'm gonna do now is I press Enter I'm gonna now carry out the reverse I'm going to choose my sphere as the object I'm going to split and I'm gonna split it with the box press Enter now what's happened here so I've split one object with the other and then the other object with the other so if I hide this sphere here you'll see and then I file hide the corner of this cube you see what I'm left with if I join these two parts together now holding down my shift key I can type in Jo press ENTER I've carried out a boolean difference if I click on my show command here you see it brings back my sphere and if I delete these now these two parts here okay so to showing you how you can carry out a boolean difference by simply just using the split command now how else could we carry out this we could use the trim command if I use trim if I execute the trim command select cutting objects if I say that my cutting object is the sphere here I press ENTER because I mean a ghost of view it means that I can click on the edge of the cube here and it will trim that part away I press ENTER now all I'm left to do is left to do is to use this object as by cutting object press enter and then I click on the edge of the sphere press enter and again all I need to do is join so there you are I recommend that you carry out these boolean type commands whilst exploring trim split and join and intersection I hope that was useful to you and I look forward to seeing you again soon thank you
