Alternate position annotation - SW2005 SP0.1

Oh, by the way, SW2004 SP5.0 appears to work properly.

WT

Why would you dimension to an alternate position view other than to show its position?

One reason is that maybe the alternate position isn't as cluttered due to its moved position. When in that position, an item might then be exposed.

WT

Why would you want a CAD system that can't do this? What if you want to show a dim between the views? For example, a travel range distance of a cyclinder.

Wouldn't it also come under the rule of not dimensioning hidden lines? Is it an assembly related dimension?

In this case, that does work, and that's why this was probably undiscovered for so long. Any annotation that also touches the "real" graphics works ok. Only those that are exclusively on the "alternate" geometry have the problem.

WT

Not quite sure what you mean. An alternate position in a drawing view is generally used to show a range of motion of an assy, so in that respect, yes, assy related.

WT

I am talking about CAD conventions not what software can do or not do. Normally hidden lines should not be dimensioned and I was thinking that also applies to phantom lines used in alternate positions.

A little off topic, but would it be nice to show alternate position view of a part. Have one configuration representing the stock (raw material) size and shape in phantom line overlaying machined part.

You can do this with an assembly. Since a part can have two or more configurations why not constrain two copies of the part to the same location in the assembly and then on the drawing make one of the configurations the alternate position.

What I don't know is whether an alternate position can be easily put on its own layer. That would give further freedom to control the view through color and line font.
