Snake Grid transformations have recently been introduced in n4ce v4.30. The Snake Grid allows n4ce to apply the same scale factor across a large model.
Using Snake Grid
To apply the snake grid, please open a Model and select Points --> Transformations --> Snake Grid and a new window will appear.
We first need to specify the .dat file. To do this select the three-dots and choose the file within the file explorer. The .dat file expresses all of the essential information about the Grid.
Next, we need to choose the original source Co-ordinate space so the transformation can be calculated correctly. In this case, I am going to use OSTN15 --> Snake. The opposite can be applied to reverse the transformation back to the original Co-ordinate space.
Out Of Area Data
The Out Of Area Data is where the Snake Grid transformation did not have an output for the data due to the Dat file.
- Delete: Removes the Out of Area Data
- Save: Saves the Out of Area Data into a Co-Ordinate Block with the name "Out Of Area" and the name of the other Model/Co-ordinate block.
