No profile is drawn in the profile view

I am a C3D newbie who used  ground survey points  (Serrano_EG_surface)  that  generated a Civil 3D surface. The white line is consist of arc segments that I turned into polylines and then  into individual CL alignments. The first alignment ,which has its left and right offsets   do not generate the profile view that I needed to be created. There was a prompt asking for a profile to choose, but I don't know where in the drawing or in the propector panel to click on.

 

1. Are the ground survey points good enough  so that any alignments over the those areas can provide me a surface profile, a design profile, cross sections every 50 feet, so that I can submit a  preliminary drawing for environmental permitting. ?

2. When I check the object browser,  the aligments preceding each other are not in the same elevation it seems. Do I have to to transform each of the polylines first into a 3d polyline and then an alignment so that I can create a profile.

3. Eventually , I wish to connect all these alignments to model a 1.5 mile rural road (more like an access road to a water reservoir).

 

4. What's a best techniques to keep track of modeling a road.This question pertains to e.g the object browser as one of the useful aid. I've also used the inquiry tool but not used it for its full potential.

 

Please respond. I've been in this rut for a few days now since I am the only one in the office who spends the time learning Civil 3d as the primary tool for modeling any horizonal civil projects. The rest are more comfortable in doing everything in Autocad.

 

Thanks.

Hello Joseph,

 

Looking at alignment Sample(3), I see that it is not superimposed over your surface. The polylines are, but the alignment is not. That will disallow creation of a surface profile.

 

To answer your four questions:

 

1. Yes, if you create a surface from those points and then create a surface profile for the alignment.

2. I think you mean the Polylines preceding each other are not the same elevation. This does not matter because an alignment is a 2d object. These plines do not need to be transformed into 3d objects.

3. I don't think you need to "eventually" combine the alignments, I think you should do this at the beginning. Use Create Alignment from Objects and select the existing polylines. They will join into a single alignment.

4. Create a corridor. This single object keeps track of alignments, profiles and assemblies (typical cross section) to model a roadway. As those design objects change, the corridor updates to reflect those modifications.

 

Best regards,

 

Tim
