TGEA's mod show, draw grids like Torque Show Tool Pro

Hi all! i'm a new man of game programming use TGEA, and i am trying to make TGEA's mod "show" works just like the "Torque Show Tool Pro". Now, i'm facing a problom may be very simple for you, that is: How to draw the grid when load in a dts shape file!

May be i should draw some lines before mShapeInstance->render(); in (\Torque\TGEA_1_0_3\engine\game\tsStatic.cpp ) or do something else ??



Thanks a lot !
