Civil 3D Point Description Coding
Yes I know most here are not fans of C3D for surveying purposes but it’s paid for and what I’m used to using for almost the last decade so for now I will have to make do as I have other expenses I’m dealing with besides buying additional software. I will admit at my last place of employment they had a very robust survey database (probably close to 300+ point descriptions & linework codes) and for the most part it worked every time so long as the coding was done correctly. But I digress…
I’ve setup a very simple and basic survey database to start off with that has simple point descriptions (each associate with a point & label style) and survey figure prefix coding (for linework with their own styles). However, what I am noticing is that when I code say the same edge of pavement (EOP) description for multiple lines of the same description type in a practice file, those lines want to link together even those some points were labeled EOP1 and other labeled EOP2. And I also can’t get linework for curves to even generate at all. I do remember this was a problem at my last place of employment (a ~25person civil/survey firm) where they had issues when they implemented the new C3D survey database coding methods and it took several months to get all of the field crews on the same page and coding features for linework correctly. However, I wasn’t a part of the database creation process nor the coding situation/learning curve in the field – I just dealt with the data import events. And before somebody says it, yes I have searched and read through multiple articles, threads here & videos elsewhere but I can’t seem to figure out what I’m doing wrong – spent almost 2 hours doing this over the past couple evenings.
That being said – can somebody who’s familiar with the coding requirements take a look at the attached image where I have added my code descriptions for survey figure prefixes and let me know how I should code the following:
- say I have strip pavement for a road and I want to pick up each edge of pavement at ~ 25′ intervals as EOP1 on the left and EOP2 on the right (for now I’ll neglect crown/CL as linework until I can master just this). How would I start the linework to tie together in ascending point order while only walking the road once and keeping the linework for the survey figures from zig zagging back & forth at each 25′ interval? Also how would I stop the linework for a particular linear feature? my practice code text file didn’t import appropriately
- say I’m picking up back of curb (coded as BC) at a radius and I want to pickup the PC, PT and roughly the mid point on the curve to give Civil 3D an idea of the radius – how should I code the beginning of curve, the point on the curve that helps define it’s radius & the end of curve/point of tangency?
