Help - dimensioning a sketched line in a drawing view

Sketched a line in a drawing view:

Dim swLine1 As SketchSegment
Set swLine1 = swDraw.CreateLine2(sngLft, sngTop, 0, sngRght, sngTop, 0)

Trying to dimension it now:

blnRetVal = swLine1.Select4(True, swSelData)
Set swDim = swDraw.AddDimension2(sngXText, sngYTxt, 0)

When I hit the swDraw.AddDimension2 line, everything just locks up.
What am I doing wrong here?

Thanxs -

I'll give this one a shot, although I'm not exactly an api knowlegeable
person.

Looks as though you are setting the annotation position but failing to give
it a value. The test macro that I ran sets this by a line following your
second dimensioning line by one that looks like this:
Part.Parameter("D1@Sketch1").SystemValue = 0.0379683
the api might be hanging because its waiting for the value. Do remember
that the api runs in meters and may need conversion.

 

This selects the line I just created:
blnRetVal = swLine1.Select4(True, swSelData)

This dimensions the selected object (The only reference required is that the
object you want dimensioned is selected.):
Set swDim = swDraw.AddDimension2(sngXText, sngYTxt, 0)

What I am doing is determining the size of my part as my drawing is created,
and drawing a boundind box around my part in each seperate view, in a
seperate layer. I am then dimensioning the 3 axis' of this bounding box,
also on this hidden layer.

My problem (just discovered) : I was running SW invisibly, and when my
dimension was created, the dimension's approve/change dialog box was not
visible, and my code coudn't progress until I did something about this
dialog I couldn't see.

What I want is to create a driven dimension, so I won't have to deal with
this dialog.
I can't find anything in the API for doing this. Changing the driven state
of an already created dimension, yes - creating as driven, No. I can create
a non-associated dimension, but thats not really what I want.

Can anyone give me a pointer in the right direction (creating a driven
dimension)?

By the way - thanks for the reply, Brian

 

Try this maybe. Tools-system options-general-clear the "input dimension
value" checkbox and the sketch-"prompt to set driven state" box also. The
macro should then funtion (eliminates the spin box from the dimensioning
process). That will create driving dimensions for those lines that are not
fully defined and driven for those that are.
If that is not what you are after then you can toggle the system
preferences values from within a macro and back again once the dimensioning
is done. Can also toggle the state of the dimension from driving to driven
if, for some reason, you wanted to leave them as driven. I don't see a way
to create a driven dimension directly if the object is not fully defined
already. Seems as though you have to create it as a driving then toggle its
state.

Even with those options un-checked, I am still having the same thing happen
