Video: Measuring and labeling values on a model using dimensioning

In this video, we will talk about how you can coordinate with other parties using the Dimension commands. This method of collaboration works best when dealing with people who don't have access to 3D software and still require technical information. So, to access the Dimension commands, we go to the Dimension menu. They are all located here, but I am going to just open up the toolbar by right-clicking on a blank area and selecting Dimension and just have these open. I am also going to go ahead and dock those by dragging, and they pop right into interface.

Measuring and labeling values on a model using dimensioning

In this video, we will talk about how you can coordinate with other parties using the Dimension commands. This method of collaboration works best when dealing with people who don't have access to 3D software and still require technical information. So, to access the Dimension commands, we go to the Dimension menu. They are all located here, but I am going to just open up the toolbar by right-clicking on a blank area and selecting Dimension and just have these open. I am also going to go ahead and dock those by dragging, and they pop right into interface.

I am going to take a quick overview by looking at the Perspective view. And just a heads up. I have got lots of curves still on this model, in a lot of locations. These are all used to generate the form, and I have kept them there. So, this is actually very handy, not only for workflow, where I may need to go back and regenerate them, but also for dimensioning. I will be able to snap two points on those curves for the dimensions. I am also going to go ahead and turn on a lot of the snaps here. That should be plain. That's most of them.

That will help me connect two points and then pull the dimensions off of those. I want to switchback to one of the Perspective viewports. I think I will start here with the Front view. And another note is we probably don't need to dimension everything on here, just a few overalls will be enough to give people the rough idea. After all, we are modeling this in 3D to high accuracy. So, when the model is finally complete, we will give them an export of the data. This is just an interim report. So, I am going to start up here with the Vertical Dimension.

Now, I can snap to one of these points on the head, and I will snap to the bottom of the shoe. This will be a good first overall, and just pull it off to the side. I will probably do another one on the other side to get the overall height, including the antennas. So, it has found the quad and mid. We can zoom in to make sure, and back out. Any point is fine. This is just to give people a rough idea. Now, you are probably noticing that the dimensions are pretty small and it's hard to read.

Let's take a look at where those options are controlled. I am going to go to the Options, which is yellow gear. And then under Dimensions, there are a couple of controls here. We have the overall scale set to a default 1. Let's just multiply everything by 4. Additionally, I want to go inside and check one other setting. I am noticing that the 136.00 is probably more information that people might need, so I am going to go ahead and lower the Precision from 2 decimal places, just to 1.

You can also do the same thing with the Angle, which we are going to do here very shortly. So, I will just hit OK. Notice this will jump larger. It's actually four times larger, and then we have one less decimal place. So, it still is accurate as the overall file tolerance, but we can reduce the perceived tolerance visible in the dimensions by adjusting that one setting. Let's continue dimensioning, maybe do a Horizontal Dimension here. To get the size from side to side.

Let's try an Angular Dimension. Let's move up to the head. Now, if I were to dimension the angle inside here, we couldn't see it, because of the 3D geometry. So, I have drawn a couple of construction lines, so feel free to get creative and add lines were needed. So, the dimension for angle is right here. We can just select these lines pretty much anywhere, and you will see how the dimension location goes either side. So, I will just click right there, so it looks good.

Now, let's try some radius dimensions. That's located here on the toolbar, Radial Dimension. I am going to start off with the curve there that we pointed out earlier. And notice that as I am going around the flat parts, the radius would be 0, so only on the curve do you get the radius dimensions. That's 7 units. I will try one more. I am going to right-click to repeat, and pick a curve there on that eye, but you can pull it out in any direction.

Just line up with the one right before. Another nice feature of dimensioning is what's called Leaders. So, we can throw quick notes on there if we want people's attention to be called out. So, I pick the Leader option there, and I am going to let them know that this is the latest version of the shoulder. So, we can continue drawing, but I am just going to draw one more point. I am going to hold down the Shift key to keep it constraint ortho, and then right-click when you are done, and then you have an opportunity to type in the text.

So, I will just say Shoulder rev 12, so they know they better stop changing it. So, with a few key dimensions and/or notes, you will be able to quickly and efficiently communicate to anyone regarding the size of the project. You are probably asking yourself, "Hey, you just said the other party does not have 3D software so how do I share it?'" Well, there is a convenient method for doing just that with a screen capture, whereby Rhino exports any of the viewports to a common image format, like JPEG.

We will cover exactly how to do that in the very next lesson.
