Add regular expression to Build dialogue

Simple expressions would be MOST helpful in building in the build dialogues esp rotation.

ie I have a prim rotated x= 345 and I want to rotate it =17 deg. enter 345+17.

or particularly moves so accurate offsets can be achieved.

Extended parsing for division and multiplication would also be nice.

most maths is simple but if i want to do a rotate 6 times.... i'm pretty quick but accuracy can be a problem esp when you don't notice it.

it's not a really big ask and reasonably easy to impliment.

THANKS

Quick note: that's not what a "regular expression" is... a better term might be a "mathematical expression".

I'd like to see this feature too, and you're not the first person to suggest it. It'd help to simultaneously increase the size of the input boxes so we can see the expression we're writing.
