hehee... yeah i know what ya mean about development
i think possibly the first problem that needs some attention are the camera controls.
don't worry greatly about any of the others but the standard Pan - Rotate - Zoom Controls
There is a problem with going outside of the JTEdit window when your moveing the camera (or anything for that matter) which means that the mouse is stuck outside of the program.
Can get frustrating attempting to get it back in, you can check for this with a combination of the AfxGetApp() cPoint.x and cPoint.y stuff

Also the Pan and Rotation should not be based upon a set scale but the current window scale to mean that it always moves the same amount - this means if your zoomed out quite a way you don't have to drag the mouse for years just to move an inch
i think you should place only a small selection of veiw tools on ... as you can only set the grids in certain veiws as certain grids - then shouldn't have them on as optional but have the option to turn them on|off on
As within the Perspective veiw a modeller will oftenly want just the floor plane that should probably be the standard. However it would be nice if you could right-click menu and have the grids on|off selection there
The zoom tool should possibly be a smooth rather than step thing ... if you allow the Zoom Variable to be accessed elsewhere this will allow you to use that figure to have some figures also always in perspective with the veiw.
A grid LOD would also help considerably. say every 50% of zoom it steps again by the ammount that is currently set.
So if your grids are 0.25 and 1.0 on a 200x200 grid and you zoom out 50% then that would automatically change to 0.5 and 2.0 - zoom out again then its 1.0 and 4.0

Means you don't get that nasty effect where all the grid spaces are blurred into each other.
Also i think the Textured, Wireframe, Vertex Points rendering should be placed within the right-click menu for the veiw.
In the end the only thing you will need to click on is Pan - Zoom - Rotation Icons for the veiw ... which makes things appear simpler even though they are just as indepth. It also leaves room for other Icons
I have alot more i can suggest but i feel thats probably the most important right now.
