Slightly off axis and may cause inaccuracies

More on error warnings.

The slightly off axis is a warning that mystifies most users. What does it exactly mean and how do you fix it.

The error message is there to warn you when you may think something is drawn; horizontal, vertical or diagonal but really it’s not. In fact what you have drawn is 0.2 or less decimal degrees off horizontal, vertical or diagonal.

To fix it, make the element exact to the horizontal, vertical or diagonal axis or 0.201 degrees or greater off he horizontal, vertical or diagonal axis. Over a 100 meter distance this could be up to a maximum of 175mm out from what was originally drawn. (The line being rotated 0.1 degrees from the its start point.)

It’s up to you to determine what you believe can be “slightly off axis” in your project. In my experience 99% of the time this warning comes up, it can be corrected. For the time, you believe it is necessary to be “slightly off axis” you really should advise your team members. As I said in the previous post, when you have one element slightly off axis, it’s likely to lead to others, unless care is taken.
