Profile Layers

[greg_garcia]

Why are my finished ground profiles coming into my profile on the layer that I have current?
I have done over 20 profiles continuously without having this problem and the finished grade
profiles for each alignment has been created to the appropriate alignment. I have 2 surfaces for sampling existing and finished grade and it no longer works correctly, is there a toggle or something to that effect that may have been reset unknowingly?

Hi Greg,

Which Version of LDT are you running? Do you have the * in the layer settings box to add the alignment name to the beginning of the layers?

[mjfarrell]

Did you happen to toggle multiple surfaces off by chance?

[greg_garcia]

MARKH - I am currently using LDT4, and all my settings use the *, to separate all layers,
alignments, etc.

mj - No the toggle is still set on, I don't understand, everything worked correctly for 20 or so consecutive profiles as I stated previously.

One more question. Did you perform a save during those 20 profiles, or have you just been creating them one after another without saving your work ( I usually do a QSAVE after each profile or step that I perform during the design process to ensure that if\when LDT crashes, I don't lose too much)? I even set up a shortcut in the PGP file to make it easier:) . I don't know how much RAM you have or if that could be an issue, but see if saving the file helps. Make sure that you have your ISAVEPERCENT variable set to 0 so it performs a complete save.

Nice tips Mark...all it takes is one time getting burned here...it's habit anymore

Thanks for the tip, memory is not an issue. I can usually blow through the profiles fairly proficiently and efficient. I guess the proper question would be, "Is there a variable setting to increase the number of layers generated for profiles while sampling from over 100 or so road alignments in one database?"

What is your MAXSORT set to? This is a Vanilla ACAD variable and I don't see how it would affect the profile coming in on the CURRENT layer. I know that there are limits to LDT due to MSACCESS limitations. Maybe you will need to create more than one profile drawing in order to work around this. When you use more than one file, do you still run into the same bug?

Just out of curiosity, what might the limits be?
