My existing surface was created by survey and I roughly have 3 points for the existing pavement (left edge, cl, right edge). I know the pavement thicknessesen-USTelligent Community 12https://communities.bentley.com/thread/321422?ContentTypeID=1Tue, 21 Apr 2015 18:27:10 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:afe99ec2-d6ba-41ca-90d5-2a8d7c108112caddcopYou might also find it beneficial to use overlay components. These have a milling option and if I am not mistaken, will follow the surface template at a vertical depth. The result would be a fixed depth even if there were more than a vertex at the three points you mentioned. Someone more familiar with them might want to verify what I am reporting.<div style="clear:both;"></div>https://communities.bentley.com/thread/321371?ContentTypeID=1Tue, 21 Apr 2015 14:53:42 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:0ee097c9-6052-4bae-84bf-ae8ccc410201Adam WieczorekWorkfow you described is correct and it is really quick way to accomplish what you need. If you are using Inroads v8i SS2 release you can create corridor on your surveyed CL and apply point controls. Providing EOPS and CL are single elements it will take no more than one minute.<br /> <br /> If you are using Inroads v8i SS3 than consider using Surface Template. You can apply pavment layers to a terrain model.<br /> <br /> I am not sure which software version you are using to help you more.<br /> <br /> Adam<div style="clear:both;"></div>
