Check Collision

Welcome. My name is Doug Morton and I'll be highlighting the advanced steel topic today. This is a fairly straightforward tool of purpose as to find situations where an element clashes with another element or with reserve space around a fastener. Once you finish your modeling and before you do your n In here we're going to come to the extended modeling tab and go to the checking area. The tool at the top is called the collision or clash check and if you run that you're going to end up going through your entire model to see if there are any collisions taking place. When done you'll see a dialog opens up and you'll have information here about the different clashes. You can sort these by clicking on the header of each col Clicking on it a second time will change it from ascending to descending. You also have in here tools at the bottom, the first button being for clash check which will rerun the checking to go to your model again. The second one will look for the objects so if you highlight one of the clashes and click on this it will point towards or highlight one of the clashes that are taking place. This third tool will clear that marking that takes place when you highlight it so set it back and remove any marking. You then have an option to ignore the objects so if you wanted to you could ignore one of the lines here in the clash check and even if you rerun it doesn't come back. So rerun in a clash check it still stays in. When you're finished going through it if you want to see those hidden items again that last button brings them all back. So let's take a look at how this works. I've run the tool I see I have two clashes. I have a couple of options here one I can highlight it and then point at it. Now when you do that you'll see my model is shaded here and so I get this kind of arrow that is hollow in the middle pointing towards an area it's difficult to see. It's often recommended when you're doing your clash check that you go to 2D wireframe. With that said you can also remove that marking by clicking on the clear marked objects. Once And I will pick my passing beam and the two beams that are connecting on either side. Just change that to vertical bolts. I want just two that's free. There we go. So I have a choice I can close this and reopen it or I can just run the clashing again. You'll see it's going through it and it tells me how collision check found no errors. Once you see this you know you're good to proceed and you can start doing your n Everything has been handled your model is correct there are no clashes taking place. If you find something that you think you don't need to address simply ignore it. One of the other things that you might be interested in setting up before doing your clash checking though is the area around the bolt. If you want to leave an area for tools when you're checking to see does anything collide with that area. To do that you come to the home tab and go to management tools. Here under defaults we're going to find if we just type in factor. You'll see there is a collision control general which gives us bolt head diameter factor. Height, nut diameter factor and height. And here we have anchors. We have the ability to set the factors for checking. And basically what this is going to tell us is we want to look at whatever the size or height of that object is. Times a certain factor one and a half, one and point seven. And so when we're looking at the imperial values basically they've been converted from metric. And the value we see here doesn't make a lot of sense. So to handle this or to see it properly we can come to the home area under unit selection. And we can temporarily change just the values that we see things in to let'say millimeter apply. Now what that does is it just it affects only the management tools. And if I come back into defaults and look for factors again. You'll notice now when I look at it, the bolt head factor is 1. 7 so it's whatever the bolt head distance is or length, size, times 1. 7. Bolt head height factor times 1. 5 and so on. So then you can set that to whatever you want. That way you get the value or area around your bolts and nuts that are also included when you do collision checking. You'll notice if I hover over it says the nut height bolt diameter times this factor is used for the collision check. And it will take into account the area required for those tools get in there and work. When it does collision check. When you're done you can simply set this back to imperial. You'll see everything the way you did before. And then you can modify. With your factor set after running the collision check. Your model should be set up so that there are no more areas where This is a good way to find out if you've missed a connection or not or parts clashing with one another that you didn't realize were clashing. It's also going to find if you have parts on top of each other. If you have a beam on top of a beam, you don't see it or a plate on top of a plate. You don't see it because they're occupying the same space. This will find that as well. So it will let It'll point to it. And if you don't see anything wrong, just check to see that there are two pieces one on top of the other the same size. So collision checking will help you find any errors. Prior to doing your n Thank you for taking the time to watch and have a great day.
