A line grid is a one-, two-, or three-dimensional grid whose intersection points represent snap points for the graphical input. It is thus used as a drawing aid for positioning objects.
In the program generations RFEM 6 and RSTAB 9, the line grid is referred to as a building grid.
Input in RFEM 5 and RSTAB 8
A line grid can be defined by using the menu "Insert" → "Line Grid" or the shortcut menu in Project Navigator – Data.
The following types of a line grid are available:
- Cartesian
- Inclined (a grid can be rotated about any axis by any angle of rotation 𝛾)
- Spherical
- Cylindrical
The origin of the line grid is defined in the "Global Position of Insert Point" section.
In the "Line Grid in X-/Y-/Z-Direction" sections, you can define spacing and the number of spans. The "Positive" and "Negative" check boxes control in which direction of the global axis the line grid is generated.
The line grid can be rotated about an axis. For this, you can define the sequence in the "Rotation" section that controls the order of the local grid axes X', Y', and Z'. In the text boxes under "Rotated about," you can then specify the rotation angle about the global axes X, Y, and Z.
