alignment/Profile command errors

[dpenney]

I am using LDC 2008 SP2 and have had a problem pop up frequently with the alignment and profile commands that make the program non-functional. When creating a new drawing from scratch and using the survey module to import points and linework, some basic functions do not work. Some specific things I noticed:

1. alignments - I can create and define alignments, but with the 'Create Station Labels' command, the routine will begin and then give a 'Unknown command "LDD" ' message followed by a decimal number. After several presses of 'Enter' each generating the same message, the labels will plot but no tick marks. This is not so bad, but the error message is worriesome. The next issue is worse...

2. profiles - when creating a 'full profile' from the defined alignment and a surface created from surveyed points and breaklines, the command starts, erases entities on the profile layers, but then generates the same string of 'Unknown command "LDD" ' message and I have to press enter to cycle through. The end result plots the profile, but does not write a profile definition block. I cannot create any vertical alignments because the program won;t create the profile correctly in the database.

Does the description of this problem suggest any ideas for how to fix it? It seems to be something that has popped up rather recently for me. Thanks.

Sounds like you need to repair your installation.

I have this same proplem. I tried to "reinstall" from the "add and remove programs" feature in the control panel. It still gives me the "unknown command LDD".

Next step is uninstall and reinstall fresh. maybe 2010 install!! Ohhh Laala.

Maybe I should just tell the PM that LDD sucks and Civil 3D works better. (((Dreaming)))

There is no 2010 version of LDT, 2009 was the last one.

Unfortunately, I'm getting the same errors as of today.
I haven't used any alignment or profile commands in a while, so I can't say how long it's been this way.
I have tried a repair install from add/remove, with no improvement like the rest of you.
Here's hoping Autodesk will see this and fix it!
Maybe if enough of us complain.... yeah right!
