add — Add a constant value to the z coordinate of a dataset or add the z coordinates of two datasets together
Syntax
...
The add command will add a constant value to a dataset or add two datasets together. The add command works on grid, cube and polydata type of dataset. The result dataset is changed.
- Grid added to grid: The two datasets should preferably have the same grid dimensions. If not the active dataset is regridded to match the window and resolution of the hiname grid. A warning is issued in the message area.
- Cube added to cube: The two datasets must have the same cube dimensions.
- Polydata added to polydata: The two datasets must have the same number of points. For polydata the target for the adding operation can be any of the xyz coordinates and scalar values.
- Adding two datasets together: The dataset in active is added to the dataset in hiname. The result data is placed in active if the lo argument is used, and in the workspace hiname if the hi argument is used.
...
Add value and result data will be placed in the active workspace. The dataset can be of any kind.
hi | lo hiname tes
Add two poly dataset together according to rules above and optionally test using the tes argument if xy coordinates are equal and then add only for equal coordinates.
