idea #247: Parametric Modeling Mode

(Sorry I don't know a better name for it)

Let we make Blender easier to use by Architect view point.

I don't use AutoCad, but my friend use it often. I got this idea from looking how easy he use AutoCad to draw shapes.

My suggestion is:

There has a button/command so you will enter new modeling mode (maybe called: Parameter Modeling Mode). A pop up window will come out. If someone think a pop up window can be annoying, I will suggest a text entry field on the header of 3D View window. No need to be large, 20 characters capacity is enough.

Supported commands are: X [value], Y [value], Z [value], DrawFace, Goto [X_Value, Y_Value, Z_Value]. More commands could be added on later.

To exit the Parametric Modeling Mode, you could Press Esc Key twice or type Exit followed by Enter Key.

For example, to draw a face. Type Goto 10, 10, 0 Enter. Followed by X30 Enter, Y-20 Enter, X-30 Enter, DrawFace Enter. A poligon will drawn with vertices on position [10, 10, 0], [40, 10, 0], [40, -10, 0], [10, -10, 0].

I know you may ask why don't just use an Add Plane command. Here is the answer. Architects often have coordinate/size that have been defined. They will appreciate to use a text based entry mode rather than mouse mode. They use numeric pad keys often, just like accounting use calculator often. So it will be handy not to change him/her right hand to the mouse. I mean he/she could use Enter Key to confirm the command (like the DOS days). So left hand to type the command, right hand for the value and press Enter Key.

I don't think Blender can take over CAD applications, but at least we try to make it more convenience to used by them. Perhaps it's hard to implemented. But it will muscle up Blender power.

How do you think?
