We're researching requirements for a feature to create PI (point of
intersection) tables in a future release of Civil3D and were hoping to get
some examples and feedback. This is lengthy.
In Civil3D (current shipping), we have a "Tangent Intersect" label that
allows you to annotate quite a few things. The label style for this can
contain information about various parameters of the Tangent Intersect point,
and Spiral 1, Curve or Spiral 2, depending on what you have and what is
selected.
So, using the "Manual" method of adding these labels, you can apply/select
the following:
1) Select an actual tangent-tangent intersect, where two tangents actually
meet end-to-end. In this case, you can label properties of the actual
tangent intersect point, plus any free curves placed between them, including
a simple Curve or a Spiral-Curve-Spiral.
2) Select a free Spiral-Curve-Spiral (SCS) entity - between two tangents, a
tangent and curve, or two curves. In this case, you can label information
about the "Virtual" tangent intersection point for the SCS, as well as
information about the Spirals and Curve.
3) Select an individual Curve - between two tangents, a tangent and curve,
or two curves. The curve can be of any type: Fixed, Floating or Free. In
this case, you can label information about the "Virtual" tangent
intersection point for the Curve, as well as information about the Curve.
Note that we already have a "Curve Table", "Spiral Table" and "Segment
Table" that lets you include those entities in a table format, but this does
include "Tangent-Intersect" labels.
So here are questions and requests:
|First| - There are some strange exceptions, where you may have a series of
compound Curves back-to-back, possibly including compound spirals. This
could be 1 to "n" number of curves and spirals. In those cases, what sort of
general rule do you use to "group" these together?
|Second| - What sort of annotation do you use to "tag" the groups, in order
to identify a given group
|Third| - What sort of annotation do you use to "tag" the entities within a
group, in order to identify a singular entity within a given group
|Fourth| - Table formats! We need and appreciate examples, as many, and as
varied as you can come up with.
You can reply to the group to any or all of the questions, any feedback is
appreciated. However, but for example attachments, please send them to me
directly, to keep posted attachments at a minumum. Address is
