Learning Curve tutorial: To create 2D views from 3D models quickly, try the ViewBase family of commands.

It was a warm and sunny December morning, just before Christmas. Captain LearnCurve, his gorgeous married woman, and their son and daughter-in-constabulary were relaxing in the lord's day on the deck of the Silver Spirit …

Await a minute! You live in Vancouver, Canada! How could you be relaxing on the deck of a boat in December?

… about 40 miles offshore from Cairns, Commonwealth of australia, just outside the Dandy Bulwark Reef.

Oh. That would explain information technology.

Suddenly a shout rang out: "Defined in the water!" With a series of splashes the Captain and his son stepped overboard, along with the divemaster and four other defined.

That's i fairly big step for Helm LearnCurve ...

Six dives in 2 days would bring the Captain's lifetime total to 226. He loves the freedom to motility at volition in all three dimensions, equally opposed to only two when he's on the surface — that's it! This month's topic!

Huh?

Generating 2d working drawings from 3D models!

But haven't you already covered that in two previous columns?

Really, those two columns inappreciably covered the one-half of information technology. AutoCAD in fact has four basic processes for producing 2nd drawings from 3D models.

Simply previously you said it had three…

More on that later. My start column on this topic covered the FlatShot command, which is the oldest and simplest. It is all the same the fastest and easiest for producing a quick-and-muddied view but it has too many limitations if you lot want to become fancy.

Adjacent came the control sequence using the SolView, SolDraw, and SolProf combination, as covered in my second cavalcade of this series. This combination is more than powerful and versatile than FlatShot only takes a lilliputian more than effort, and in one case again has a few limitations and gnarly bits.

The Power of Positive Procrastination

Time and the Autodesk programmers marched on. In due grade they produced the SectionPlane family of commands, which made it much easier to produce 2D drawing and cantankerous-section views.

And AutoCAD 2012 introduced yet some other series of 3D-to-2D commands, which brand it well-nigh trivially piece of cake to produce second drawing and section views from solid models. (So by delaying this column until now, I take cunningly avoided the need to write i about the SectionPlane family.)

In my first commodity near 3D-to-2D, I bragged that I had created four ortho views and an isometric view in under five minutes. Well, using the ViewBase command I can reproduce that drawing in well under one minute, assuming I have the 3D model to begin with.

I'll demonstrate, using the same simple part from the before commodity. (You can download it if yous want to follow along.)

1. Open the drawing file.
2. Click on the Layout 1 tab to make it current.
3. Delete the existing viewport. (You lot tin eliminate the demand for this step in futurity drawings by deleting it from your template file.)
4. Start the ViewBase command. You'll find information technology on the Ribbon menu > Layout tab > Create View panel > Base of operations push. A layout tab has to be current for the Layout tab to testify. A couple of paragraphs back, I bragged that I could create the second cartoon views of our sample function in under a minute. Okay, start the clock!
5. Having started the ViewBase command, click on From Model Space in the driblet-down menu that appears. One Mississippi …
6. AutoCAD asks for a view location. Click approximately in the heart of the lower-left quadrant of the drawing, then click leave in the context menu or press Enter. … two Mississippi …
7. AutoCAD continues asking for view locations. Click in a higher place the first view, and then to the right of the commencement view, so approximately in the center of the upper-right quadrant of the layout, so press Enter.

… iii Mississippi, four Mississippi … and stop the clock, which shows that it took just a few seconds to produce the figure below. That's a bit faster than the xvi steps I outlined in the previous article, isn't information technology?

With the ViewBase command, it took merely iv seconds to produce this drawing!

Ah, but the ViewBase command is fifty-fifty trickier. For starters, information technology assumes that y'all are going to create at least the three basic orthographic views — front, top, and end —and so information technology automatically scales the 2D views to suit the page layout sheet size. We'll take more than on this after.

Now we want to add a few dimensions, merely there isn't plenty room between the views to fit them in. No problem; simply click anywhere within the top view, then utilise the little blue square grip to drag it upwardly a bit. Oops, we forgot to turn Ortho or Polar on — wait a minute, we don't need to! Orthographic views can just be moved vertically or horizontally, regardless of the Ortho and/or Polar settings! Similarly, moving the base view brings all its ortho children along with it, while isometric views remain contained.

Okay, we've added a couple of dimensions to the paper space layout, equally shown below. For best results with dimensioning I would propose using Object mode or EndPoint object snaps to attach the dimensions.

We moved the top view upwards and added 2 dimensions.
