Anyone know why when I'm creating contours and a tin, the program will not pick up all the points I entered. The maximum length of for the tin is set for 150' and it won't pick up points on the other edge of pavement, 20' away. The points were entered in the point block and the 3D edge lines were also selected, but it skips areas and points???
thanks
Go to the SUEFACE tab, select TRIANGULATE & CONTOUR, select the TRIANGULTE tab and make sure that the SIMPLIFY SURFACE box is not checked.
I've had similar problems with 2008. Mine would pick points that I DIDN'T want. Now I just copy the .crd file, rename to "Contour Only" and delete the unwanted points(also delete all the points from the actual drawing), set the contour file and then select "all" when asking what points to use. It's an added step but it seems to work for me.
I hated typing in the ranges for all the shots anyway.
Hope that helped.
I create an ascii file of the points that I want it to use, and use inclusion and exclusion polylines. Never had a problem doing it that way.
(I don't want to change my crd or go back and forth with multiple ones)
all my field is split into 4 layers:
Topo
Location
Traverse
Check
Isolate the topo and run with it.
Are you creating points on a real Z? I do.
I like to use Simplify Surface when possible. It make a tenth of the triangles and is easier to edit. But in this case I had to uncheck it for some reason.+
I also, try to block my topo points to help with pulling out the contouring points.
thanks
Simplfy surface generally is done by ignoring your break lines and many of your shots. I NEVER use it. It gives bad data, unless you have a small topo with no major elevation shifts. If the area is flat as a fritter and you have only taken 100 or so shots and there are no ditches or curb lines, you may do fine.

Aside from Simplify Surface, other possibilities might be exceeding the maximum length of a TIN triangle and possibly the "Non-Surface" toggle available in Field-to-Finish. Another option is if the points were subjected to the Non-Surface Points/Entities routine. If you'd care to send me your DWG and the settings of the Triangulate & Contour routine via its Save button, I'll see what I can find out.
I have seen that Carlson has problems triangulating when breaks lines either cross or intersection each other. But the intersection is not at a common vertices. When this happens Carlson tends to ignore the data. In this case InRoads will create a common elevation and coordinate at the intersection of the lines and note it. Carlson does note the intersection, but you must address them manually.
