# Geometry Creation
The three most common methods of inputting data into GSA are manually, sculpting and copying.
# Manually
Insert data manually in a tabulated format.
Select an item from the data list in the Explorer Pane, to bring up its corresponding input table.
# Sculpting

# Copying

Data can also be inputted:
Via a text file (advanced option) - Copy data out in GWA format, edit, and replace.
Using an API - Using an Application Programme Interface to create and edit GSA files.
