Hi Paul, it will be cool to see what you build!

If you need to draw something of an exact size, it is easiest to draw it that size right from the beginning. You can usually enter specific values for things. Like for instance if you want to draw a rectangle of a certain width and height, enter that width and height in the command options area which appears in the upper-right corner of the screen.

You can also use "distance constraint" when you are drawing a line (or other things) - to do this, enter a number in the "d" box that shows the current distance from the previous point, it is on the bottom toolbar right below the current x,y,z coordinate display (which is also where you can enter a specific x,y,z coordinate for the point you are currently drawing).

There are some shortcuts for this also - most of the time if you just type a number it will start your typing in the first available numeric edit field.


One quick note about Rhino - you can actually copy and paste objects back and forth between MoI and Rhino, so it can work pretty easily to move something into Rhino for some particular operation that Rhino does, and then bring your model back into MoI again.
