## How do I fillet, chamfer, and dimension in isometric?

That's it, really. I can draw block thingy's in isometric, and I can even simulate circles with ellipses. However, three things elude me in isometric: chamfer, fillet, and dimensioning. I can't find anything useful in on-line tutorials. Can someone please help? Thanks

## Re: How do I fillet, chamfer, and dimension in isometric?

To clarify, you are asking about isometric drafting? not an isometric view of a 3d space?

If that's the case, then a fillet rould need to be an isocircle (ellipse) that's trimmed backto the lines. and the lines trimmed back to the isocircle. Chamfering you'll need to lay out by hand, eg measure back on each plane the chamfer distance, and draw the chamfer lines in.

Dimensioning just takes defining an appropriate style -- a couple of nice samples have been posted here in the past.

I don't expect that any CAD program will provide better tools to do isometric drafting, (or cabinet projection, or cavilier projection either). Doing 3D is where the trendiness is. About the only place that isometrics have in CAD is as riser diagrams,,,,,

I'm definitely a novice in Autocad but I use a .lsp routine for my isometric views. All my drawings are in 2D, no 3D stuff.

See the attached for iso dims.

For a fillet, especially a small one I wouldn't go through the trouble of using an isocircle, by the time you trim away all but 1/4 of it, it will look almost identical to just using the fillet command. Just experiment with sizes until you get it close.

Chamfer is simply measuring along two sides to identify the end points and connecting the dots.

Not sure if you realize, but the SNAP command has a style option that will simplify isometric drafting, setting the crossharis at the correct andgles for isometric, and making it easy to toggle thru the isometric 'planes' by tapping F5, When Snapstyle is set to Iso, the ellipse command automagically offers an option for an isocircle on the current plane.

Heh, heh. Thanks for the info but I'm still using Autocad for DOS.

Thanks for the answer, Cadtag. I was scared you would say that. It seems I am doomed to be a bit old-fashioned!

However, others have casually mentioned that " ... dimensioning just takes defining an appropriate style ... ". No-one yet has given me any indication as to how to do that. I have no idea what you are talking about. Would you please explain in more detail?

Thanks

Draw in plan view, then change the view to iso metric. Then save the view as a WMF & import that file with WMFIN command. Dimension to your style preference. I would change the end tick angles, and incline the text.
