Highlights today:
- Change the custom text of a dimension string to reference their distance from datum model elevations, for example, sea level, or project zero. Bonus: how to change the datum reference of all placed spot elevations globally.
- Set the corner and perimeter elevations of meshes first.
- Don’t use curves in meshes to keep the polygon count low. This is a corollary of our general rule to keep the node count as low as possible with a mesh.
- How to use custom data elevation settings when establishing mesh elevation parameters (sea level, project zero).
- Import pdf site info into the model via a worksheet, and view in the model environment by means of trace reference. Otherwise you will need a dedicated layer for each new imported document. Not the end of the world, but using worksheets to keep imported alien data organized is a sound practice.
- Cut and Fill calculations: make a copy of the existing terrain, develop the earthwork design on the copy, then use the element info palette to compare cubic volume of the two.
- Use gravity to place level dimensions to a mesh surface, as you would with other objects.
