Creating Circular Viewports

|

Do excuse my slight absence from making any new and substantial posts here over the past couple weeks. Just last week the May/June 2007 AUGI World magazine was shipped. Just as the May/June issue was shipped the submission deadline for the July/August AUGI World came up. As you may have guessed I will have another article in that issue, talking about Thematic Mapping in Map 3D. No less with everything behind me now you can expect more frequent posts once again.

To kick things back into gear I’ll offer up a quick tip on making circular viewports. This one came up just the other day, and so I figured I’d share the quick tip with you. Anyone using layout tabs has likely become an expert at creating rectangular viewports. Whip out the MVIEW command, or just click the (single viewport) toolbar button, and within a few clicks you have a rectangular viewport. But what if you want to do a circular viewport? It’s a common request for those wanting to “zoom” in on an area within a plan. Luckily, if you’re familiar with creating normal rectangular viewports than circular viewports will be a cinch.

  1. Using the standard AutoCAD CIRCLE command, draw a circle to represent the viewport boundary in your desired layout tab (Left circle in illustration).

     

  2. Using the MVIEW command, type OB for object and select the circle you drew in step 1 above. You can also use the “Convert Object to Viewport” button on the “Viewports” toolbar (illustrated below). Upon clicking the circle, AutoCAD will create a viewport which you can configure the same as any other viewport in AutoCAD (Right circle in illustration above)

     

Again, not necessarily a revolutionary tip, but definitely one that gets overlooked quite frequently. With my AUGI World deadline behind me, stay tuned as I will work to get The CAD Geek blog caught up once again.

  1. I have created a circluar viewport to zoom into an area in a larger area. But the viewport below still shows through. Is there a way of clipping the larger viewport or using the circle to wipeout the viewport below?

  2. yup i agree susi, sucks big time. i suppose were lumbered with the old retangular one. surly ther must be a way to use the command line to create it, im relativly new to this autocad stuff, as i only did enough on it to generate line drawings to import into 3Dmax for 3D work so dont know to much about the internals of it but thers nearly always a workaround,someone somewher will know how to make that command line work, i doubt my new employers will want to buy the full blown version tho. lol.

  4. Hi Ramin,
    there must be a reason for LT being LT and that is one of them – you can’t produce polygonal viewports and therefore no circular ones either. Really annoying.

  6. hi all, im using AutoCAD LT 2004 and tried to create a circular viewport, looks like the option for creating the object to viewport toolbar isnt even in the menus that i could see, maby this version is to old but i failed to find it.

  8. And unfortunately it isn’t. That’s the one thing I am really unhappy about LT. Apart from that there is not too much difference between a full and a light version. LT doesn’t work with images of course but that’s it as far as I learned using it.
    Thanks anyway :-)

  10. I already knew about that and always found it very useful but now I am working with a LT version of AutoCAD 2008 and it drives me mad not to be able to create viewports as I like…
    I suppose there is no creative way around that?
