Re: profile starting and ending station, not sure what they mean

I don't know what to say on this. This is a step back from LDT.

Some major confusion at Autodesk about what is important.

I just setup a quick test in 2013. Even trying to change the station of a PVI to a value before the alignmnet start station yields an Argument Exception.

Bringing this up one more time. Partha, hopefully you see this and can comment on where this stands in the wish list. I'd think that something we've been asking for since 2008 would have gotten closer to implementation.

this is hilarious, I had forgotten about it, but checked my .net tools that manipulate c3d objects and found this statement:

 

bool trimmed = ceProf.TrimToStaLimits(alg.StartingStation, alg.EndingStation);

 

So it seems my tools have been trimming the profiles for years now, and still are for 2014.

That function is a bool, because I use that to warn the user it was trimmed.

 

We don't care much though, about C3D funkiness, as Autodesk sucessfully motivated us to write our own alignment and profile program that works on AutoCad and BricsCad. Soon I will be exporting C3D surfaces to text file and using ceometric surface library to handle surface use. The Autodesk monopoly is splipping fast.

The work around I've been using recently is to add an alignment segment to the begining/ending of an alignment, make the change, and then delete the alignment segment. It sucks, but gets the job done without crashing the program. Seems like all that needs to be done is delete a line of code from the API that is doing the check, test, and compile. Definitely seems like a programmed limitation that doesn't need to be there. I'd be really surprised if it took more then 2 days to make the change for this.

I guess that works when you have the alignment as parent, not a data-ref.

In my case, I do, but if I used c3d in production, we would never put our profiles in the horizontal design base.

 

With all this Caltrans hoopla, you would think its super common to have highways that start in the middle of a vertical curve.

It would seem an embarrasing thing to tell users they must make overlapping alignments in order to get the VC at end of existing, and beginning of proposed.

That kind of duplication is not liked by designers, especially when you have a highway split up into segments, and each company has a definate start/stop on their segment.

 

But the caltrans issues have not even started from what I have seen. This darn web DG inteface keeps me from watching posts like I used to though.
