Manage data files and the sequence of operations for greatest efficiency.
Unless you need to edit points and point groups, add a point file reference to the surface definition rather than importing the point file into the drawing. This keeps the drawing smaller and easier to process. If your surface is composed from several point files, merge them into one large point file to improve performance.
If you add point data and breakline data (breaklines or contours) to a surface, add the breakline data first. The breaklines define specific surface features such as walls or ponds, so if they are present before points are added, the breaklines support the creation of a more accurate surface model. For more information, see The Effects of Operation Order On Surfaces.

- Filtering Point Files
Ensure that your point file does not contain more points than required for your surface.
- COGO Point Label Visibility
For COGO points in a drawing, you can improve performance by turning off the point label visibility.
