Hiding dimensions


How can I hide a dimension which is driven by one in a different plane? For example,
I want to have dimensions in the side view equal to the corresponding ones in the
top view, but I do not want to have to show them twice.

Re: Hiding dimensions

John,
It sounds like there are two things here you need.
1. You can easily use layers to control the display show/hide of geometry
and dimensions you place on your drawing. Whichever layer is active at the
time an object is created is the layer the object goes on. Any layer that is
not active may be turned off. Any geometry that is on a layer that is turned
off will not be displayed. You may also move an object to different layers
after they have been created.
2. Equal dimensions - Have you been using formulas to controll one dimension
being equal to another? you state that you have a dimension on the top view
and another on the side view which are equal. Wou can maintain equality of
the one on the side view with respect to the one on the top view by using a
formula on the side dimension and setting it equal to the top dimension. All
you need to do to change the geometry of both top and side is to change the
dimension for top.

Re: Hiding dimensions


Thanks, Ricky -- That is very helpful. I had not thought of using layers to hide
those surplus dimension marks. I have been using formulas, but was finding that
I end up with way too many dimensions on the layout -- between the top view and
the side view, where tangent and colinear relationships etc. can't be set up, I
was displaying duplicate dimensions to support the formulas. Now I can hide them
in a layer.
I am having a devil of a time tracing relationships -- I know how to locate and
delete them with right-clicks but can see no easy way to see the "direction" in
which they were set up. That is, if I have a cascading set of spatial relationships
among many parts, I can't think of any easy way to find the "mother" of those relationships
except by looking for a "black" driving dimension, which doesn't always reveal itself
readily. It happens all the time when I try to move some part or change some dimension
or relationship, and either the entire drawing moves or I get a message of rebuke.
Do you have any tips to find the origin of the relationship set, or alternatively,
do you find yourself following any convention such as always starting on the bottom-most
or left-most element. This is the one area where I am wasting most of my time.
I am loving this software, which I am using for trivial but complicated schemes
like music boxes for grandchildren. Not a user likely to generate a big sale for
Siemens, I fear, but becoming a good friend none the less.

Re: Hiding dimensions

John,
You should take a look at your overall methodology. Using dimensions to tie
top and side view is not the right way to go. You should be doing this with
relationships and then dimensioning only the top or side view. Take the
example of a box (an oversimpllification for sure):
Draw the box in the top view say, with Tools --> Maintain Relaitonships set
to ON.
Now, select the two lines the would extend down into the front view if they
were infinite --> With them selected look on the ribbon bar for a little
icon that looks like something about infinite lines and toggle this on.
notice how the lines extend down into the front view.
Now place lines in the front view which connect to these.
Then, go back and toggle off the infinite projection.
Now, notice when you move the lines in the top view, the ones in the front
extend automatically.
Give this a go. If this is not clear, I'm sure Ricky can walk you through it
or point you to a help article or such on the subject.

Re: Hiding dimensions


That's brilliant, Dan just the trick I was looking for, though too late for this
complicated thing I chose for my first project. I instinctively drew the front
first, and that's where lots of the driving dimensions reside. Having the front
100% driven from top and side never occurred to me. These fine points didn't seem
to matter when I took my mechanical drawing class fifty years ago.
