Old CG point and drawing files

[CG Survey]

I can import a drawing file from CG DOS, and open the coordinate file, but cannot "associate" the point file with the points and lines.

Any advice as to the best way to do this?

Thanks

The old C&G Dos pl1 nd Pl2 files can be converted to DXF / DWG but the
CRD file attributes do not follow. A simple drawing may recreated by
plotting the point, lines and calls again. A more complex drawing, how
bad do you want it, because it requires the same method.

I don't think there is any way to do this. I have to go through this all the
time when we have to go back to an earlier drawing, it's frustrating. I end
up deleting the points in the DOS file, converting the drawing to DXF, then
replotting the points in the new DWG file.

The way we handle reattachment of the coordinate file to the drawing is to
convert the .pl1,2 files to .dxf, then to .dwg in CG-*CAD as you describe.
In Coordinate Management create a really high point number, i.e. 64000 with
some fictitious value. In General Options set "next point" one number
higher, i.e. 64001. In Traverse Options set "horizontal distance tolerance"
to a value, i.e. 0.001. Then run AutoCreate Points in Coordinate
Management...check boxes "points, lines and arcs" as appropriate, then in
the drawing select the geometry you want to reconnect, making sure the
supporting drawing layers are showing (or not showing). We usually turn all
the layers on and pick everything. When you've completed your selection set
and <entered> to process, existing points in your file will be compared to
the end points of lines, arcs, radius points,...and if a fit is found within
the tolerance you've set, the points will be reassociated. If a fit isn't
found, then a new point will be created. In DOS "extended lines," for
instance, don't have point attributes, but they will be created by this
method. In the example here any new points will be readily apparent as they
have point numbers above 64000. When through we delete coordinates greater
or equal to 64000, leaving us with the original coordinate file.
Unfortunately, deleting the coordinates doesn't destroy the newly created
attribution of say a line that originally was an extended line from point
#1, and when "queried" is now defined as #1-#64001. When a legit point
#64001 is eventually created, that original extended line will magically
snap to the new #64001 unless you go through CGDraw and "drop the CG
attributes" for this and every other potential self-drawing line. With the
high point numbers, such should not be the case! Hope this helps.

This is excellent Gary. Thank you for your help.
