Yet Another Way to Get from 3D to 2D in AutoCAD

Learning Curve tutorial: To create 2nd 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 wife, and their son and girl-in-law were relaxing in the sun on the deck of the Silver Spirit …

Await a minute! You lot live in Vancouver, Canada! How could y'all be relaxing on the deck of a gunkhole in December?

… about twoscore miles offshore from Cairns, Australia, just exterior the Nifty Barrier Reef.

Oh. That would explicate it.

Of a sudden a shout rang out: "Divers in the water!" With a series of splashes the Captain and his son stepped overboard, along with the divemaster and four other divers.


That'due south one adequately large step for Captain LearnCurve ...

Six dives in two days would bring the Captain's lifetime total to 226. He loves the freedom to move at will in all three dimensions, as opposed to only ii 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 hardly covered the one-half of it. AutoCAD in fact has four basic processes for producing 2D drawings from 3D models.

But previously you lot said it had iii…

More on that later. My commencement cavalcade on this topic covered the FlatShot control, which is the oldest and simplest. It is withal the fastest and easiest for producing a quick-and-dirty view but it has besides many limitations if you want to become fancy.

Next came the control sequence using the SolView, SolDraw, and SolProf combination, equally covered in my 2nd column of this series. This combination is more powerful and versatile than FlatShot but takes a little more attempt, and one time once again has a few limitations and gnarly bits.

The Power of Positive Procrastination

Time and the Autodesk programmers marched on. In due course they produced the SectionPlane family of commands, which made it much easier to produce second drawing and cross-department views.

And AutoCAD 2012 introduced yet another serial of 3D-to-2D commands, which brand information technology nearly trivially easy to produce 2d drawing and department views from solid models. (So by delaying this column until now, I have cunningly avoided the demand to write one about the SectionPlane family.)

In my first article about 3D-to-2D, I bragged that I had created iv ortho views and an isometric view in under five minutes. Well, using the ViewBase command I tin can reproduce that drawing in well under one infinitesimal, bold I have the 3D model to begin with.

I'll demonstrate, using the aforementioned unproblematic office from the earlier article. (You tin can download it if you want to follow along.)

  1. Open the cartoon file.
  2. Click on the Layout ane tab to make it current.
  3. Delete the existing viewport. (You can eliminate the demand for this step in future drawings by deleting it from your template file.)
  4. Beginning the ViewBase command. You'll detect it on the Ribbon carte du jour > Layout tab > Create View panel > Base button. A layout tab has to be current for the Layout tab to show. A couple of paragraphs back, I bragged that I could create the 2d drawing views of our sample part in under a minute. Okay, offset the clock!
  5. Having started the ViewBase control, click on From Model Space in the drop-downwards carte du jour that appears. 1 Mississippi …
  6. AutoCAD asks for a view location. Click approximately in the center of the lower-left quadrant of the drawing, and then click eXit in the context bill of fare or press Enter. … 2 Mississippi …
  7. AutoCAD continues request for view locations. Click above the first view, so to the correct of the commencement view, then approximately in the eye of the upper-correct quadrant of the layout, and then press Enter.

… three Mississippi, four Mississippi … and stop the clock, which shows that it took just a few seconds to produce the figure beneath. That's a bit faster than the 16 steps I outlined in the previous article, isn't it?


With the ViewBase command, it took simply four seconds to produce this drawing!

Ah, but the ViewBase command is even trickier. For starters, it assumes that you are going to create at least the three basic orthographic views — forepart, top, and stop —and and so it automatically scales the second views to suit the page layout sheet size. We'll have more on this subsequently.

At present we want to add a few dimensions, but there isn't enough room betwixt the views to fit them in. No problem; only click anywhere inside the top view, so utilize the trivial bluish square grip to elevate information technology up a bit. Oops, we forgot to plow Ortho or Polar on — wait a infinitesimal, we don't need to! Orthographic views tin only 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 independent.

Okay, we've added a couple of dimensions to the paper infinite layout, as shown beneath. For best results with dimensioning I would suggest using Object mode or EndPoint object snaps to adhere the dimensions.

Nosotros moved the top view up and added two dimensions.
