what's up guys Justin here with the sketch of essentials calm back with another sketch up quick tutorial for you so in this video I wanted to go through a couple of the different ways that you can cut holes and openings in your Sketchup model um today's videos brought to you by my patreon supporters so patreon as you know is the website where you can support creators that you like on YouTube so I want to say a big thank you to my two newest supporters Lucan art and Joseph wood so if you like what I'm doing in this channel if you're enjoying what I'm doing with the Sketchup essentials maybe consider supporting the show on patreon you can check that out in the link in the notes down below let's go ahead and just jump into it alright so the first way to cut holes in objects and Sketchup is simply to use the push/pull tool so most you know you can use the push/pull tool to push-pull geometry in your model um what some people don't know though is they don't know that you can actually use this to cut openings and the way that you do this is you take faces and you extrude them so that they're level with the back face of your object so in this case for example if I was to maybe try to cut a window opening in this in this thickened wall here what I would do is I would push-pull this face to the back side of this object and you can see if I push pull this so that it's level with the backside Sketchup will create a hole here so if you push-pull this too far obviously it's gonna create this extra geometry and that's not what you want but if you push-pull this then if you push pull this directly so that it's level with the back wall then you can use it to cut an opening one thing to note about this is it's really best to single click with the push-pull tool active and then move your mouse just up anywhere along to any point that's on the backside of this object so you can see how I can click anywhere because I'm locked to push pulling this way or this way the inferencing will make it so if I click anywhere on a point on the backside of this object a hole will be cut and so the same thing worked with this circle if I was to push pull this back and I was to click on this back line since I'm level with the back side of my object the push-pull tool will cut a hole in this face so you can use this to cut holes very easily so that being said sometimes this doesn't necessary work so like for example you can't push pull on a curved face so I wouldn't be able to come in here and just draw a circle on this curved face and then push a hole through because you're not allowed to push pull curved surfaces in Sketchup but what you can do instead is Sketchup has this handy little function called intersect with model and the way that works is let's say for example that I needed to cut a hole in the middle of this object and I'm gonna make sure that I go ahead and position it correctly before I do this but let's say I wanted to cut a hole just right in the middle of the geometry of this object just like this well what I would do is I would just select this in here so that all my faces were intersecting then I could right click and click the option for intersect faces with model and so when I do this and I can go ahead and delete out all this extra stuff now so now if I was delete it to delete out this face you can see how basically this geometry all intersect it in here so really everywhere that the geometry intersected Sketchup created edges and faces so you can see I was able to cut a hole that way so in the same way I'm gonna make this a little bit smaller if you remember so if you remember before we were able to cut one hole in this object with the push/pull tool but then let's say that we needed to cut another hole in this object going the other direction so you can see how this gets kind of weird because these faces are intersecting on the inside and so you're not getting like the full hole creation process in there but if you select everything right click and you go down to intersect faces with model then you can delete out you can see how this intersected all of your geometry in here so you've got kind of your different faces so you can see how now I can see through this opening and you may have to play around with this to get it to create the geometry that you want but it works really well for intersecting different faces and what I use this for a lot is I actually use this a lot when I'm working with like countertops and that sort of thing like if I'm cutting an opening for a for a sink for example so I've got my countertop in here that I created well what I'm gonna do is I'm just gonna select everything that's in here and I'm just gonna right click and I'm gonna click intersect faces with model and that may take a little while just because it's intersecting a whole lot of geometry in here because there's more edges inside the sink all right so you can see how now there's kind of some extra edges in here because Sketchup went through and intersected this face with your component in here but now you can just come in here and you can just delete out these different layers that it created so I'm just clicking and hitting the Delete key so you can see how I was able to use intersect model to kind of cut out the different layers in here and the one thing that I'm not a giant fan of is it did seem to create a little extra geometry inside my sink here but what you could do is you could just come in here and you can select it all and you could just do an edit hide and hide that geometry to make this smooth if it really bothered you so you can see how that's a quick easy way to cut a hole for a sink in a cabinet all right so number three is you can create a cut component to cut a hole in a face if it's a single face so like for example if you had a building here and you didn't care about having walls that had thickness then what you could do is you could come onto this face and you could draw a rectangle and then you could double click on it and you could make it a component and we would call this something like window but you can see how down below this gives you an option to glue to a face and to cut an opening and so what this is gonna do when you select this is this will cut an opening inside any single thickness wall that you put it in and we'll talk about doing this at a double thickness wall in a second but you can see how you can set so that this will glue to any vertical face any horizontal face or any face in here and so once we do all of this we can go ahead and click create so because this is a component what I can do is I can use the move tool and copy mode to create a copy off to the side over here and then I can use this to model out my actual window off to the side so instead of having to deal with it being in the wall and all of that what I'm gonna do is I'm just gonna give this a little bit of depth for my frame so maybe like a thickness of two inches or something like that and then I'll delete out this Center part well you can see what that does because this is a cut component inside of an individual wall what it'll do is anywhere you place on
Thanks for your comment Nelly Balduf, have a nice day.

who wants up guys Justin here with the sketch of essentials comback is another Sketchup quick tutorial for you so in today's video I wanted to talk about an easy way to use solid tools to cut holes in objects in your model so if you're looking for more time-saving tips for Sketchup make sure to check out my free Sketchup tips guide at the sketch of essentials comm slash tips now let's go ahead and just jump into it alright so I got a question a while ago about the easiest way to cut a bunch of holes into a shape like this one and so one of the things you could do if you really wanted to is you could just draw a circle on one of these faces and then push pull through like this then you could start kind of copy pasting that geometry but then you'd have to delete out edges and intersecting things with your model and it just really really wouldn't be very pretty I mean it would definitely be in here you could definitely do that but it's probably not the best way to go about that and so I was looking for like a quick easy way to cut a bunch of holes in an object like this one and probably one of the easier ways that I came up with is to use solid tools so from result tools is one of the tools and Sketchup that allows you to basically change the way that solids interact so objects that uh that don't have any holes in them or internal geometry or considered solids by sketchup and so what we would do in this case if we wanted to do that is i would create a hole like this one and I would put it outside of my group of the object that I wanted to cut through and what I would do is I would double click on it and I would make it a component and what I would do is I would call this just hole or something like that it doesn't really matter what you call it and we'll make sure the box or replaced selection with component is checked and we're gonna click create and so then once we do that we're just gonna make our copies and that's kind of the nice thing about this is this allows us to come in here and create all of these different copies and I'm using the move tool and copy mode right now and I'm just adjusting the number of arrayed copies that I'm creating in here but that way we can come in here and we can lay out these circles in whatever way that we want to before we try to cut holes or anything like that so let's say for example that I was to maybe take these holes and kind of put them in the center like this so I'll just use the move tool in copy mode again in order to place my holes and so once we've got all of our holes added here what we can do because these are all components is we can actually actually push pull these in order to give them thickness and then once we push pull these to give them thickness you can see how they're intersecting with our model right now and so once we do that what we're gonna do is we're gonna use solid tools which is built in in the Sketchup pro version in order to cut our holes and so there's two different ways that you could do this the first is that you could use the subtract mode and do each one of these individually but obviously that's going to take a certain amount of time so the way that works is you use subtract mode you click on one solid then you click on the other solid and it'll subtract that in here but you can see how each one of these if you did this individually this would take a lot of time so what we're gonna do instead is we're gonna subtract all of these at once and so you can't do that just by selecting them all you can see how this tells you this requires exactly two solids so what you can do instead because these are all individual solids is you can group all of these together and then you can go inside of this and explode all of these and you do have to be a little bit careful because when you do this these aren't components anymore but I'm gonna go ahead and explode all of these and I'm going to click outside of this group well now this group contains a number of different solids but it's being treated like one solid you can see how this is in here as a solid group because all of the geometry in here is solid and so what that means is now I can come in here with the subtract tool and I can click on the first solid and then the second solid and it's gonna come in here and it's gonna cut holes for all of these so it's gonna remove the geometry where the first group is intersecting with the second group and I will say that this does take a while so it'll sit here and spin for maybe a minute or two doing this actually that went really fast that actually went a lot faster than I expected it to but you can see how that's a quick easy way to cut a bunch of holes in a shape really easily and I would recommend maybe when you do this possibly like making a copy off to the side before you do this I'm just in case you have to change any of your spacing or any thing like that but you can see how that was really easy this is still in here as a solid group because we use the solid tools interacting with each other so that's where I'm going in this video leave a comment below let me know what you thought was this helpful to you did you know you could do this with solid tools I just love having that Sketch up conversation with you guys if you like this video please remember to click that like button down below if you're new around here
