CreateLinearDim4 - What am I doing wrong ?

I have a horizontal sketch segment that was drawn within a drawing view
using drawdoc.createline2, and I am trying to create a non-associated
dimension that displays the length of this line(top line of a square, whose
sides are defined as dblLft, dblRght, dblTop, dblBott).
No matter what I do I can't get this to display anything like what I need.
Can anyone see what I am doing wrong?

dblXTxtPos = dblLineCenter
dblYTxtPos = dblTop + Inch_to_Meter(0.25)
dblDimVal = swLine1.GetLength
dblTxtHght = swModel.GetDefaultTextHeight()

vntDimP1 = Array(dblLft, dblTop, 0)
vntDimP2 = Array(dblRght, dblTop, 0)
vntDimPlaneDef = Array(dblLft, dblBott, 0)
vntDimEx1 = Array(dblLft, dblTop + Inch_to_Meter(0.062), 0)
vntDimEx2 = Array(dblRght, dblTop + Inch_to_Meter(0.062), 0)
vntDimTxtPos = Array(dblLft, dblTop + Inch_to_Meter(0.062), 0)

Set swDispDim = swDraw.CreateLinearDim4(vntDimP1, vntDimP2,
vntDimPln, _
vntDimEx1, vntDimEx2, vntDimTxtPos, dblDimVal, 0,
dblTxtHght)

My dimension with these figures comes out in the center of my sketched
square(origin point), with the text and a single arrow displayed - nothing
else.

Has anyone ever used this, or know of a code sample somewhere?

Thank You

One thing that makes it easier for us to help you out is to show the
entire code for this section. If not, we do not know where the dbtop,
etc values are coming from. It is very hard to help out with only a
snippit of the code.

Have you verified that the point values are correct for placing the
dimension?

 

These variables (dblLft, dblRght, dblTop, dblBott) were filled with
dimensions pulled from my models polyline pts.
These are the values that were used to create my lines that I am trying to
dimension, so yes, I am positive that they are correct. (And yes, they are
in meters.)

My sketch is of a simple rectangular box, and my code is simply trying to
create a dimension relative to, and displaying the size of, the top
horizontal segment of this box. The reason I want to use this non-associated
dimension type is only because I don't want my code execution to stop for
user approval of a driving dimension. This is just going to be a reference
display.
My box is defined by TopLeftCorner(dblLft, dblTop, 0),
TopRightCorner(dblRght, dblTop, 0), BottomRightCorner(dblRght, dblBott, 0),
and BottomLeftCorner(dblLft, dblBott, 0).

Sorry - I tried to make that part of it clear without having to post
extensive amounts of code showing how I came up with my polyline pts.

Thanks

 

Here is some code that will show what I am trying to do. This creates a
front view of the part - if you change it to a right-side view, you should
be able to see the dimension. No matter what I change, or how I change it, I
can't seem to get it to come out where I want it.(I think in inches, so if
your metric, you'll have to change a couple of figures)
