AutoCAD: Tips & Tricks

– [Instructor] Welcome to another AutoCAD Tip and Trick. And again, we’re on that constraints theme. The constraints in AutoCAD. So you’ll see we’ve got a new drawing for you, it’s called clamp_constraints6.dwg this time. You can see it at the top of the screen there. When you download it from the library to follow along with this Tips and Tricks video, make sure you don’t confuse it with any other of the constraints drawings you may have downloaded. This particular drawing has all the settings for both geometric and dimensional constraints that you need for this particular Tips and Tricks video.

So, let’s jump straight in this time. I’m going to show you now how to work with showing and hiding all of your different types of constraints in your AutoCAD drawings. So, at the moment, right now, you can see all of your dimensional constraints. You’ve got d1, d2, d3. D2 and d3 have expressions associated with them using parameters, which is d1 plus null .25, and they’re all locked, you’ll notice, as well.

They’re always locked. So, how do we hide them? Well, I’ve mentioned this in previous Tips and Tricks videos, as well, but if I want to hide all of my dimensional constraints, I go to the parametric tab on the ribbon, into the dimensional panel, and just click on Hide All. And all I can see now is the clamp in the clamp drawing. Now, if I want to show them again, and show all of them, I click on Show All, and they all come back. Now, one of the benefits you do have in the dimensional panel is this, Show/Hide.

If I just click on Show/Hide like that, it now says Select Objects. If I select d2 here and click on it, and then press Enter to confirm, I’ve got an option. I can either show it or hide it. If I hide it now, it hides only that one dimensional constraint. I can do that with the other two, as well. If I do Show/Hide again, and select this one. Right click or press Enter, I’ve got the option of Show or Hide. I’ll hide that one, too.

Same again, Show/Hide, select d1 this time, right click, show or hide, and I’m going to hide that, as well. I’ve now hidden all of my dimensional constraints one by one individually. I can either have one or a number of dimensional constraints depending on which ones I want to see. I can easily go back to Show All, and they all come back again. Quick and easy. Okay, so, let’s do a Hide All now on our dimensional constraints, like so.

They’re now all hidden. What I need to do now is jump over to my geometric panel and I’m going to click on Show All. Now, there’s all of my geometric constraints this time. You can do the same with your geometric constraints. I can hide all of them. Click on Hide All, like that. I can show all of them, and the process is the same. I can show and hide them. If I go to Show/Hide here in the geometric panel, and come in, Select objects.

Let’s hide that horizontal one there, like so. I select the object. You have to select the object with the constraint on it, like that. Press Enter to confirm, and you’ve got the choice of Show, Hide or Reset. So I’ll hide that one. Can you see it hides it and any other associated geometric constraints. It’s important that you realize that because sometimes you’ll get two geometric constraints disappear and the reason that they were joined together, so to speak, is you had a horizontal and the perpendicular.

This line here and this line here were associated to each other by the perpendicular constraint. I can bring those back by clicking on Show All and they all come back. You’ll notice the tangential one disappeared, too, because that relates to the horizontal, yeah. It all kind of works together with the geometric constraints. What about that Reset setting, though, how does that work? Let’s go Show/Hide again and we’ll select the same line. That one there. And then all I’ve got to do is press Enter and it’ll give me the options.

If I reset that, what happens? Nothing in this particular case because it’s all back where it should be. But what I can do is, I can perhaps click on this coincident point here. If I click on the line and click on the grip and do this, like that, can you see? It all moves in relation to the geometric constraints and the dimensional constraints. I’ll just hit escape, though. Now, let’s try that again, Show/Hide, select the line, and I’ll do the Enter or right click, and I’ll do a reset.

Again, it resets but it’ll only reset to the original horizontal line because that was the constraint I selected. Just be aware of that. You can reset the settings of the constraints if you want to, depending on what you’ve done with dimensional constraints, geometric constraints and so on. The idea is that you can show and hide them at any time. That’s the benefit. And you can show and hide individual constraints, as well. If I just wanted to see the clamp drawing now, I’d hide all of my geometric constraints and I’d hide all of my dimensional constraints.

I can now show all of my dimensional constraints. Again, we’ve got that funny little quirk. You’ll notice that dimensional constraint has gone flying over there, so just select it, click on the grip, bring it back to where it should be, click again, and it’s back where it should be, hit escape to deselect. The dimensional constraints sometimes do that when you’re zooming in and out. It’s all to do with this dynamic constraints setting in the dimensional constraints. Okay, so that’s pretty much it. That’s how you can show and hide all these different constraints that you can create in your AutoCAD drawings.
