Inventor isometric views are NOT to scale

Inventor isometric views are NOT to scale

Inventor isometric views are NOT to scale

(OP)
I was just recently informed that the isometrics that inventor inserts into it's drawings are not to scale. A quick measurement confirmed this to be so. Is there a way to ensure they come in at their proper scale?

RE: Inventor isometric views are NOT to scale

Isometrics are true projections.  Therefore lines not parallel to the screen are foreshortened.  This is taught in Drafting 101.

Inventor 2009 allows you to put on the true dimensions or the projected dimensions.

I'm sorry but you're wrong. Read up on the subject here.

http://en.wikipedia.org/wiki/Isometric_projection

Isometric views are not projections of the true image because the sides are supposed to be equal length.

I would like to attain true isometric views from inventor not representations.

RE: Inventor isometric views are NOT to scale

foreshortening of isometric views is based on a factor of the square root of 2/3. You can multiply your base view scale by the inverse of that to get an isometric view as you want it.

So if your base view scale is 1/2 (or .5) then make your isometric view scale .6125  (.5 x 1.225)

RE: Inventor isometric views are NOT to scale

Gabriel, from your wikipedia reference, isometrics are a type of projection:

"in which the three coordinate axes appear equally foreshortened "

A di-metric projection keeps one axis with no foreshortening, and may be what you are looking for?
