Hi all, during lockdown I am trying out some new workflows. My goal is to become proficient in grading lots and create a surface that ties in with a road corridor.
In my test drawing I have:
- Parcels of lots and ROW, generated using various parcel tools including slidelines and swinglines.
- Road and adjacent footways surface generated using a corridor.
- Building pads generated by feature lines and grading.
All was going well until I tried to grade the rest of the lots (outside the building pads). My issues started when I tried to assign elevations to the parcel segments. The drawing became unreliable and frequently crashed. My parcels segments lost their shapes (in particualr the swinglines went a bit crazy).
My question is: what is everyone's preferred workflow when it comes to grading?
Some ideas I was going to try out:
- Keep parcels 2D only, draw feature lines on top of the parcel segments and use them for grading
- Extract feature line from corridor and use grading tools to reach back of lot
- Extend the roading Corridor using a generic LotGrade link to and target a feature line at the back of the lots
