What did we get ourselves into when we started a simple write up on Parcels?Read more
Ah well. Inside AutoCAD Civil 3D there’s always more to the story.
In the last few Parcel posts we learned about the Site Parcel Feature’s topology engine. We unwrapped this planar and nodal based topology model that underlies how Parcels work. This unique engine powers the design functionality we get out of Site Parcel’s dynamic model in…Read more
Why does the Site Parcel’s Feature Line collector have a single Style-based Priority property? The need for the property isn’t really apparent at first glance. It becomes more evident when we begin to understand the depth of the Site Parcel and the dual power of the built-in Site Parcel model.
In the last post, we discovered…Read more
The last Parcel post we met the AutoCAD Civil 3D Site Parcel’s planar nodal topology engine. This is a model somewhat like the surface model we know all too well. The familiar surface TIN eats point data (x,y,z locations) and it’s triangle edges are edited and forced by breakline data (x,y,z pairs).
The Parcel topology model plays by another set of…Read more
In the previous post we talked about how the related civil engineering disciplines “see” parcels and their data differently - so much for getting a nice brown-paper wrapper and a string on the parcel. Much like junk mail these differences of expectation will continue to show…Read more
