Dimensioning the CAD model - AutoCAD Tutorial

We're staying in the CADmodel.dwg file. And as you can see, we still have the point cloud attached, the StBarts1.rcp file. Now, what I've deliberately done is I've put us in the top view using the St. Bart's UCS that we set up previously. Now we set that up when we were putting the polyline in for the outline of the church. Now, if I can just mess around here and go up to there and go to the world coordinate system, you'll see it drops back to 0, 0 there, which is the original insertion point of the StBarts1.rcp file. Now, in order to get our dimensions aligned, though, we want to make sure that we're using our St. Bart's UCS. You can see they're all lines in with the line of the church. Now, the one thing with point clouds is they're big, they're colorful, depending on whether you've got the colors switched on or not. And also, you can't see much geometry. Now at the moment, our RCP file is on the layer zero. Now, what I'd like you to do is go to the Home tab on the ribbon, go to the Layers panel. Go to the dropdown here. Make sure that Dimensions is the current drafting layer. And then what we also want to do is go to the layer dropdown again, go to layer zero, click on the sun symbol, and you'll see that freezes that RCP. And that's really useful now because we can easily see the polyline that forms the outline of the church, the geometry that we've created from our point cloud. I'll just click in the drawing area again to get the cursor back up. Now, obviously, this geometry at the moment is pretty basic, and I wouldn't expect it to be anything otherwise. And as I've stressed throughout the course, what we're doing here is giving you a workflow. Your call to action is to go and expand on that workflow and make things happen for yourselves, based on the knowledge you've gained from the course. Now we're on the Dimensions layer. If you go to the Annotation flyout here, you'll see that we're using Metric_ANNO as a dimension style. Make sure you're using Metric_ANNO. That one there. And also down here on the status bar, you want to make sure that your annotation scale is 1:100, because the viewport in the ISO A1 - Plan View here is also 1:100. Notice it's 1:100 there. Also, make sure that your viewport is deactivated. I've left mine activated for some reason. Come outside the viewport, double-click. Just make sure it's deactivated for the minute. We're then going to jump back to the model tab, and we're just going to play some simple dimensions. So zoom in nice and tight. Make sure your object snaps are on and just check that you're on the St. Bart's UCS there on the ViewCube. And I'm just going to place two simple linear dimensions. Now I'm just going to use the Annotation panel here. Go to the flyout, select linear, I'm going to go endpoint, snap there, endpoint, snap there. Drag the dimension up a little bit. There you go. Just get it to about there and click. So there's one dimension. Linear again, endpoint there, endpoint there. And then what you want to do is just zoom in a bit and just get that to line up. You should hopefully get an intersection or an endpoint, one of the two. And as you can see there, just lines in nicely and the dimensions look nice. So you've got that in place. Don't worry about switching on the RCP file again. Now, you can if you want to, but you won't be able to see much because your dimensions and your geometry will be hidden by that point cloud. The whole idea of the point cloud is you use it to generate the geometry, and then you can start generating a drawing with dimensions, annotation, et cetera. Now, if we jump to the ISO A1 - Plan View layout tab, you'll see that the dimensions aren't there right now. Don't worry about that. Double-click inside the viewport. Just go here. Set your annotation scale to maybe 1:50. Click again, set it to 100, and you'll see those dimensions appear. It just needs a reset on the viewport scale to make sure that they display. That's all. And that's quick and easy to do. Again, though, remember to deactivate your viewport by double-clicking away from it. Now, as you can see, the sheet is very basic. It has one simple viewport at 1:100. Now, obviously, you can go off and create some other viewport and some other layout tabs if you want to based on this particular drawing with the RCP file attached. Something you might want to do is perhaps create another layout tab with another viewport with the RCP displayed, and you could maybe set that up and have a nice kind of point cloud view showing in a viewport on a sheet to give an overall kind of experience of St. Bart's Church in the drawing. But that's basically how you would dimension the geometry that you're generating from the point cloud that you've brought into AutoCAD from that original drone data.
