How to Use REVIT MEP 2008 - Massing Objects

Hello and welcome back to our CADclip lessons on massing and mass objects. In this lesson, we are going to show you a little trick that my buddy Wes Markley showed me some time ago about using a void, the kind of a donut effect to remove some area and do something that probably most people would not think of. So I am just going to show you that little aspect design tool. I am just going to start by going to my level one. I have got a grid line, grid line one X on here and I am just going to start by creating a blend or could be an extrusion that goes across and then I am going to create a void with an inner and an outer ring and you are going to see what happens with that. So I am going to use create mass because I might want to turn it into a roof later. So I am going to say create mass and I am going to call this saddle dome one, hit OK. And now, I am going to start by doing a solid void and in this case, I think I will just keep it simple and do a solid extrusion and then I am going to set my work plane to be on the grid line one X. Hit OK. It is going to switch your view, thank you. Open the view and now I am down drawing on that grid line. So now, I can start by saying OK. I am just going to go in and draw you know a couple of arcs. I am going to draw an arc from here to here, go up like that maybe I will use my offset tool and offset by two feet, click there. Then I will go back and draw some more lines using line and then click on there. Now, I am going to zoom in and check my corners here and I am also going to go like this, I am going to go ctrl+C, copies that to the clipboard. Click out and then I am going to say—oh, I thought I was going to do a blend. I do not have to do that. I am just going to say finish the sketch because I am in extrude not blend and then I can go look at that in 3D and say OK while there it is. It was not wide enough, no problem. That is the beauty of the emplaced massing. I can just stretch that and then I am done. That part of it. Now, I need to do the void part. So I am going to go up here to my site plan where I can see that. From the top, maybe I can even see it from my level too. Now, I am going to create a void form and a void extrusion. And with that void extrusion, I am going to use for instance an ellipse and watch how I do this. I am just going to pick a point somewhere in the middle and make an ellipse that just kind of fits inside there. I am going to hit escape. Now, I am going to do an offset and say offset by 12 feet just to get an outer. Click on there and hit escape. Now, I am going to take this but that was not enough so I am just going to delete that. I am going to do an offset again and I am going to make it 20 feet just to make sure and then click out and then hit escape. Now, this is a void object which means that if there is a donut, what happens is this will provide—the void will actually be this part. So what it will do is it will remove this material from that other object and leave inside here in the middle. And I can say finish the sketch and now I can go to my 3D view and there is my void object. The only thing is it is not overlapping which is not a problem because beautiful RIVET, I can just click on here and I can bring that down, maybe bring that down to there. Now, I am going to do my cut geometry, cut this from this, click out and that is what I am left with. Finish the mass and there I have it. Now, I can say roof by phase, you can pick on there, create a roof and then I can start to add some skylights perhaps, right click, add select, create similar, start adding skylights into my saddle dome etcetera and things like that. So, I am just going to delete this roof and reverse engineer that for you. So now, what happens is I have a family here. I am going to edit that and what that is made up of is this solid extrusion right here that went from there to there and then I created a void which is this object. Now, I am going to try that maybe with a blend. I was going to do with the blend. I might as well have got a little bit of time. So I am going to go dow
