Which framework / feature is best to create mini CAD

[geokes]

Hi,

new to graphics programing, very excited about HTML5 and webGL.

I would like to create a few simplistic browser based 2D CAD applications but don't know if any of the game frameworks would be suitable for the task.

If yes, which specific features would I use (tile maps, sprites etc.)?

Is there any way to deal with measurements (inches / millimeters)?

 

Here is an example:

Floor Tile pattern designer:

Create a floor (wall) with precise measurements.

Select / create a tile  with precise measurements and realistic texture.

Select space between tiles.

Create a grid from tiles which can be moved / rotated as a grid.

Once the layout is finished, create a list of how many tiles are needed and how many needed to be cut and in which way (diagonally, horizontally, vertically)
