# FabriCAM Software CAD Tangent Practical Exercise (Part 2) Step by Step Video Tutorial

Now that we have had a look at the Tangent Lines to Arcs tool, lets have a bit of a practical.

This is by no mean going to be the most simple practical, as we are going to mix a few different tools that we have to use.

This video is part of a Mini-Series.

Alright guys, In today's video, we're going to be looking at a practical for our tangent option located in the cat feature. But before that, let's have a quick intro first. So today's video can be found on softwaretraining.co.za z day. We make sure easy to watch problem solving videos and we also have the updates otherwise back in the programme here. Now, in today's video is practical. We're gonna be looking at creating this type of shape. So the basic gist of it is it's a form of arc with a few straight lines and a circular cutout. Now, the important thing about this is the circular cutout I want to be located on crossing point of two tangents. And then, um yeah, the rest. I'm gonna live up to you guys. So that's kind of the requirements, but yeah, otherwise you can pause here, try it out. And then afterwards you can see the process I took and go from there. Well, let's see. Uh, yeah, I'm hoping you guys gave it a try. It's a little bit of more complex tutorial this and so I hope you came, right. So what? I'm gonna do is I'm gonna remove all of this and then start without design, I'm gonna start with adding the ark as it's the most complex part. I'm gonna go to Option two and then because I wanted to talk to the right, I'm gonna invert the value. So normally I would work from zero to whatever value this is. But now I'm gonna work from zero with number three. So I point number two there or point number three to the value on top year. So first of all, I'm gonna go on my ex. I'm gonna leave those zero so it stays on the X value, and then I'm gonna make my Y in this case also, uh, yeah, I was gonna say zero because this is I'm used to using that as a starting point, but the sum this is gonna be 100 so it's gonna go up. It's gonna become act as if it's a third point. Then the bottom one is gonna be 00. So now it's gonna be coming from up here, going down, then for the middle curvature. I'm gonna go 50 exa 15 and 50. So it's in the middle of that. So Okay. And there we go. We've got a curvature. Now I'm gonna add a line to the right of that. So I'm gonna make this, uh, let's go x 100 for both. So 100 to the side, and I'm gonna make the height of this 100 and say, Okay. And then we've got our line not to join these two. There's two ways you can go about it. The first way is the one we covered. So the under the lines we go to line two points, select the first point, then, uh, we select the second point is zoom in there so I can find it. There we go. So that's one way we can go about it. Other way is we can actually use a tangent tool, so I'm gonna select both of these flick on the tangent, the second one. Select the bottom out spot, and then the hot spot. You're on this actual line. You can see it creates a tangent line there. Then we want to locate the intersecting tangents. So I'm gonna select both the shape, go to the same tangent to select the bottom, and this time I'm gonna go the opposite corner, and then I'm gonna select once again. But there is using control and collect the tangent. Tool top. Right. And now the bottom left. There we go. We've got a crossing point of two tangents. So now all that's left to do is to find the location of that and add our shape. So not to do the location. I'm gonna use the location, identify you on the bottom. Right? Zoom in. You probably won't be able to see my digits easily while I've got while I'm at the right location, so I'm just showing you where it is. Then you wanna take your mouth and your harvard, you can zoom in. But what you wanna do is harder as close to that centre crossing as you can over there. I've got 62.11 on my ex and 50.47 on my wife. So now I know that exactly middle of this is 50. So I'm gonna round both these off, so I'm gonna go 50 and 60 to 62 on my ex and 52 on my wife. So now let's go to the circular tool. I'm gonna say 100. I'll show 10. Rather I don't wanna do 110 and a single positioning. Now, I'm gonna add those values up here. So that means 62 the y must be 50. So okay. And there we go. I've got a little circle cut out there in the centre I'm gonna do is just remove. Uh, unfortunately, there is no one do. So let's do that again. We've got 10, then I'm gonna go single position. Go 62. You can actually find this more if you zoom in and you can get the exact but I'm just going around at the number right now. There we go. We've got our shape with cut out on the tangent tangent crossing, which is quite convenient, but yeah, otherwise, that is on the practical. Like I said, there are rather complex one. So I hope you've learned something here and then just get frustrated. Otherwise, if we head here to softwaretraining.co.za see, you guys will notice We've got a variety of different Softwares we do cover. And you can also isolate your search on the top, right? If you do not however, find the training videos. You're looking forward. Just simply go here, request the training video filling in uniform, and then we'll do our best to try and make that for you. But otherwise thanks, guys, for watching and just
