Edit Grid

A Grid object models a surface via rows of point lists. In the 'Grid' page, the 'row' field indicates the row number that is being edited. Adding and deleting a point to the current row is the same as adding or deleting a point in a line.

Create a grid object:

1. Select the Model page in the Main Window, then select the Grid subpage.
2. Type in "front" in the current object field and press 'Return' to create a grid named "front".
3. A small dialog box will pop up to let you select a texture image name. The image you select will be used as the texture map on the grid. If you do not select any image, the new grid will not have a texture map.
4. Select point "a" and then point "b", by clicking the Shift-left mouse button on them. Make sure the order is point "a" first and "b" second. This adds two points into row 0.
5. Click the small up arrow beside the "Row" field in the Grid subpage. This increase the current row to 1.
6. Select point "c" and "d" to add them into row 1.
7. Change the row number to 2.
8. Select point "e" and then "f" to add them to row 2.
