Join Dave Schultze for an in-depth discussion in this video Creating screen captures for quick proofs, part of Rhino 4 Essential Training.
In this video, I will show you a very cool technique to not only capture your Screen viewport but also stage the entire scene from maximum effect and more efficient communication. So, don't worry. This is more about art and impact than it is about learning any new technical commands or procedures. First off, I want you to make sure we are in an appropriate and logical stage in which to share the design. So, I am going to go ahead and maximize the Perspective view. What we are about to do is going to significantly increase your file size, so I suggest you make an additional layer, and we're going to call it copy.
I have already got it set up there. Now, I am going to do a couple of short steps here. I am going to just select everything. I am going to copy that data with Ctrl+C. It's a lot of stuff, so sometimes you have to wait a little bit, depending on the model. Ctrl+V to Paste. Once it blinks, that usually means it's done. Now, we have two copies on top of each other, so carefully, without deselecting, I am going to hit Ctrl+G to group them together, just the new stuff. And then I am going to take that group and we can just drag it over.
So, I have got two copies of the same robot. Let's switch over to the Top view and make another change. I am going to place this copy on to the copy layer, just to avoid any problems. Now, I am going to go ahead and rotate this copy robot. You can pick any point inside of them. It's not that critical, and then I am just going to type in the command line 180, to flip him around.
Maybe scoot him up, not quite back to back, and a little offset. You will see why here in a second. I am going to go back to Perspective viewport. So, here is the general idea. We are going to be documenting the model and its progress by seeing copies of two different views. So, we get the idea of how all the design looks from almost every angle. Now, before we do a screen capture, there's several things we definitely would want to change. Right now, we have kind of a light gray background. We have a grid that's kind of in the way, and a few other things.
So, let's go through four steps. A lot of times layers will be multiple colors. For example, that copy layer might have been bright green. That would be bad. We want to have everything if possible just be black. This would give people a neutral view of the model, so they can focus on the design and not be distracted by layers or colors. The next step is I am going to make sure our camera here, which is a perspective camera, is a little bit on the wide angle side. So, the place we check is by right-clicking on the viewport. Last option is Viewport Properties, and here's the default lens size.
It's 50 millimeters. That's kind of a neutral lens. We are going to exaggerate this just a bit by typing in 30 and hit OK. Now, it looks like we jumped back. Actually, we didn't jump back. We just got a wider angle. I am going to turn the grid off. The shortcut for that is F7. Get that out of the way. Finally, you want to get the background color to be white, so that when we place this on the document, we don't see a big square rectangle around the objects we are supposed to be focused on. So, we are going to check on the tools options or click on the yellow gear.
Under the Appearance > Colors, we have Viewport. Background. That's the medium gray we are looking at right now. So, let's click on that swatch and select white. I am going to maximize this perspective. I usually like to get somewhere about mid-height on the project. So, we are looking up at the top and down at the bottom, usually more dramatic. That's not quite as interesting. So, zoom in, rotate as needed.
Now we are ready to capture. So, we do this by right-clicking on the viewport label and this works for any viewport, by the way. Select Capture > To File. I am going to call mine capture 02. So, we have now made a snapshot of the entire screen viewport, and we will be able to bring that into another document or just send it as is via e-mail. Switch over to Word and take a look.
Here we are in Word. This is an earlier screen viewport capture, and we will pop the new one in right here at the top, and then kind of compare and contrast. So, I am going to select the Picture > Insert, capture 02, scale this down a bit, and check the wrapping. So, now you can see the difference. We have got this very clean image, which we can then crop further, expand or shrink. You can put some text next to it.
So, the focus really is on the object with any nodes and compare that to another screen capture, with all the defaults. Not nearly as compelling. So, with the Rhino Screen Capture command, you can now collaborate with colleagues or just show off your Rhino modeling and robot designing skills with anyone. Just follow these four short steps, and you will be able to tell a more compelling story in a few pictures.

Q: I'm noticing several differences between the options that author shows in the video and my copy of Rhino. For example, I can't select curves on the edge of a surface or turn on control point when vertically extruding a closed surface like an ellipse. Also, I do not get the Sweep option. I'm running on Mac OS X Snow Leopard.
A: This course was recorded on a Windows computer. As of February 2012, Rhino for Mac is still in beta, so it is not yet a full-fledged product. Wait until the full version comes out to see if these issues are resolved.
