Re: COGO Pts along CL

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.

Re: COGO Pts along CL

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?
