Churchill RE: Civil3D and Surveyors (I wish my surveyor would. "Is it the only lesson of history that mankind is unteachable?" He made the change (it was quick for him) and all subsequent drawings were much easier for us to work with. After dealing with this a couple of times, I asked if he could modify the block so that each element was on a different layer, so we could freeze the parts we didn't want to show. All four entities were on the same layer, but I didn't want the point number or "boat" on my base map, only the point and the elevation. These blocks were created with a LISP routine he had written. For example, years ago a surveyor I worked with many times produced all elevation points with a block that contained the point, the point number, the elevation, and a surrounding "boat" (a five-sided figure that was basically a rectangle with one end "sharpened"). After all, a CAD drawing is data and data needs to be properly organized.Īnother thing is to work with the engineers you consult for to make sure your CAD drawings integrate seamlessly into their workflow.
This is a very rational layer scheme and once implemented across all your projects, it helps your own survey drafters to better organize the survey drawings. for Version 3…I didn't find the most recent version in my quick online search). I recommend using the AIA CAD Layer Guidelines (see. This makes it very time consuming to clean up the survey for use as base mapping. Even from the same surveyor (actually, the same drafter), I often get different layer schemes from one project to the next and almost always a fair portion of the entities are on the wrong layers. For me, the #1 thing is rational naming and organization of layers, then making sure the entities are on the correct layers.
