A Free Form mass element contains a large number of grips. Displaying all
grips can slow down the performance and be unnecessary for using the mass
element. There are two ways to control the display of grips on mass elements:
â– By default, the grips on a Free Form mass element are only displayed if
their number does not exceed 2000 grips per element.
â– You can turn off the display of grips in the drawing altogether if you click
➤ Options, then click the Selection tab, and under Grips, clear
Enable Grips.
A surface in the LandXML Schema contains information about the surface
name, type, 2D and 3D area, and the maximum and minimum elevations. It
also contains information about each of the points and faces that comprise
the surface. The surface information is merged into one composite mass
element body, which can have thousands of faces. Applying a surface hatch
or texture map to a complex mass element can be quite time-consuming.
