Way to find wall attributes for length and angle

[dwyckoff]

What is needed is a way to query a wall and have it show the angle and length information without having to place a dimension. How many times I have found a wall that is just slightly off axis or not exactly on a 45 degree and you don't know it until you try to intersect another wall and they don't clean up.
Is there no way to have the data supplied with the other attributes?

Hello Roberto

which are these solutions?

Well, the most used is to check if the difference from the two values is smaller than a very little number (tolerance).
Eg.

eps = 0.0001  ! <-- tolerance 
 
IF x = 0 THEN GOSUB "errorcheck" ! <-- BAD CODING EXAMPLE 
IF ABS(x) < eps THEN GOSUB "errorcheck" ! <-- GOOD CODING EXAMPLE 
 

The first comparison (the "wanted" one!!) can result in an error message.
The second one checks if the value of the variable x is "near enough" to zero (the "ABS" function ensures that the tolerance works for values above or below zero are).
