Redundant dimensions

Is there a way to tell proe that a specific dimension should not be a show dimension? For example I have a pattern of boltholes where most of them are in line, so I only really need one dimension to show. Also, if I constrain a hole to a dimension and use zero as the value, this will show up using show dimension. I don

One possibility is to pattern only the in-line holes in a single
direction pattern which would avoid the unecessary 0 dimensions and
then use feature/copy/dependant/same references to create the
out-of-line holes.



Do you need to pattern anything else to this bolt hole pattern?

Yes, once this part gets assembled, it will have bolts placed into the holes.

Another way would be to use View -> Show/Erase rather thanshow dimensions - this allows you to click on each feature in the model tree to select all of the dimensions relative to the feature & to erase the ones you don't want to see.

The picture is of a part I have modelled according to my above
descriptionthat should simulate what you are trying to achieve
albeit not in a single pattern.

One base feature and two patterns of holes for a total of 9 features.


The first pattern of5 holesis a table based pattern
inthe xdirection only. The second pattern of3 holes
is a table based pattern in both x and y directions. Allhole
details areidentical and changing any one will change all of them.


However there are NO zero dimensions, NO duplicated dimensions and
NO redundant dimensions so I can Show All dimensions and not have to
worry about it

Yes, the pattern in one direction works very well, however with your second pattern none of the holes are in line. In my case, say one of the three are in line, this yields another dimension, with the same value in the x as the hole it is in line with.Follow me?

I see what you mean in this case, and a single hole above any other
hole can be done via a similar method without redundancy or zero
dimensions.



Depending upon EXACTLY what you want affects the possible methods of
achieving it. Any chance of a picture of your current arrangement.

I haven't tried this, but I believe you can put the redundant dimensions on a layer. Call it junk_dims or something, then hide it onthe drawing.
