hi, dont know anything about direct x really, have the following code that draws a rect. D3DRECT Rect1 = { GridTopLeftX+8 + row*20, GridTopLeftY+2 + column*20,GridTopLeftX+5 + row*20, GridTopLeftY+14 + column*20}; Rectangle32Fast( &Rect1, D3DCOLOR_XRGB( 0, 0, 0 ), g_pDevice ); I want to be able to draw a different shape, i.e. a cylindrical shape or a square with a rounded top, do any of you guys think you know how to do this? many thanks steve

Generally when getting to complex shapes it's sometimes beneficial to create meshes of these shapes. If you are in the situation that you need to create these in runtime you could follow some algorithms to help you in the process.

Always try and break the problem into smaller pieces like take for example a cylinder. You have a top and a bottom made out of circles and then if you fold open your cylinder you will have a rectangle.

I would suggest that you give us a better explanation of what you want to do and maybe we can help you get on track.

I hope this helps.
Take care.
