Q - question

Evaluate math expressions in AutoCAD DWG texts.

A - answer If you have a drawing with texts containing arithmetic expressions of any complexity, you can use the freeware utility EvalText to evaluate those expressions and optionally write back the results.

Download the EvalText LISP file from Download, load it into your AutoCAD session with APPLOAD and type the EVALTEXT command to start the tool. Select all texts containing at least two numbers and formatted as a proper arithmetic expression by the VBscript rules (syntax) - e.g. 5*(3+5*4.8)^2. EvalText displays the result (3645 in this case) and you can optionally write back the result over the original expression.

In addition to standard arithmetic functions and parentheses, you can use the following functions in these expressions:

  • Int - integer part
  • Fix - integer part
  • Log - natural logarithm
  • Oct - octal value
  • Hex - hexadecimal value
  • Rnd - random number (0-1)
  • Sgn - sign of the value
  • Sqr - square root
  • Abs - absolute value
  • Exp - e raised to the value
  • Sin - sinus
  • Cos - cosinus
  • Tan - tangens
