COGO Pts along CL

How can I insert COGO points along the CL of an alignment? I've designed my vertical in the profile view. Now I would like to see spots every 25' in plan view. I see all codes except CL or crown. ETW, sidewalk, daylight, etc...

Depending on which sub assemblies you used you may be looking for ETW instead of crown or CL. The median flush subassembly places a crown coded point, the lane assemblies for the most part place a ETW coded point. If you right click on the subassembly tool and look at help it will have a diagram showing how the coding is taking place.

that's not good. Guess I'll have to convert back to LDT. Grrrrrrrrr....

There are some options under the Create Points command to do thi. You can place points on alignment points of curvature and also by measuring/dividing an alignment. If your alignment starts at a whole station location, then you should be able to locate points at other whole station locations using the measure option.

Define EP alignments etc. if you want to set points on those using the same method.

If you create a corridor, then you can export corridor points (cross section) to Cogo points.

Andrew, are you associated with AutoDesk? You are hiding behind your email address.

You could say that I am associated with Autodesk in that I work with their products.

Points at cross section locations, with elevations, can be exported from a corridor model. And yes, the corridor model is built by assigning a typical section (assembly) such that they are perpendicular to the direction of the alignment. Therefore offset locations of EP points etc. reference CL stationing.

Andrew: Please re-read my question. I didn't ask about corridor or cross section elevations. My questions follow your remarks. Have a nice & happy New Year.

Thanks Bill - yourself a safe and happy new years as well.

Are you wanting to set points on existing features at perpendicular cross section locations?

""...If you create a corridor, then you can export corridor points (cross section) to Cogo points."" Yes, but you cannot export CL points like you can in LDT. The measure along alignment command does not allow you to pull elevation from a DTM or Corridor surface either. So guess I'm still stuck.

Dave, I thought some or other approach by one of our users would suffice your requirement; There are many subassemblies which contains CROWN as point code and you can extract COGO points at every station at which assembly is applied and this CROWN point is available. If there is no subassembly that suffices your design requirement and output requirement together you need to modify some subassemblies so that you get what you need. I would like to suggest another approach which i am sure would give you necessary results for you. Referring your original post, suppose you want to extract COGO points and label them along the centerline (or baseline) of a corridor at every 25'. Assuming that your current assembly is not good for this do following: 1. In your tool palettes - go to "Imperial - Generic" tool palette; and select "marked Point" (available in generic tool palettes that were shipped out of box with Civil 3D) subassembly 2. As you select this "marked point" subassembly to attach AutoCAD OPM (properties) dialog appears and one of the input fields in it is Point Codes. Enter CL (or whatever you like) against it. 3. Add this "Marked Point" subassembly and attach it to the "baseline marker" of Assembly (to do this pick the vertical line representing baseline at the center of assembly, or the one you see as you start building the assembly). 4. Now run this assembly along a baseline to build corridor with frequency of 25' (or whatever you choose). 5. At this point use Corridors -> Export -> Corridor Points as COGO Points and select CL (or the point code you entered) as code to extract. You can use these marked points any number of times to mark any place in the assembly and label as whatever you want (although these MarkedPoints have even bigger role in the assembly building!) Finally, I would say subassemblies have to be used as it is to extract all Key Features such as CL and CROWN points without any special treatments and we will look into that issue why they are not working (and in what cases) to improve out of the box content. Thanks and I hope these steps help you. -- Chakri Gavini Product Designer Autodesk, Inc.

Thanks for the advice Chakri. I've tried the second approach that you outlined and all sounds logical, but I cannot seem to get the "CL" marked point to appear within my Corridor codes. I've tried many different ways without success including your step-by-step instructions. This should not matter, but I am using the Metric - Generic tool palette to select the "Mark Point" since my project is metric. I am using LandOutsideSuper subassembly to define a two-lane travel way. This subassembly does not include a Crown point code. I guess I could use BasicLane, which has a Crown code included, but then I would have to define a separate profile for each Edge of Travel Way where the pavement goes to a superelevation condition. Could there be a step that I'm missing to have corridor see the marked point subassembly definition?
