Formula will not allow a line to the left of an existing line

Need help? We are here.

I’m sketching a wall for layout of some wainscoting. I drew a vertical line pattern to establish spacing, now I’m adding more vertical lines to represent the width of the stiles (3.5"). However, if I change the measurement between the two lines to a variable (StileWidth), the app puts the line to the right of my existing line. I deleted the new line and drew it the left, but as soon as I assign the variable, it moves to the right side again. I tried making the distance negative -(StileWidth), but the app said this is an invalid expression.

Any help is appreciated.
Thanks!
Eric

It must have something to do with the pattern constraint. I deleted this constraint and now it will allow a line to the left. However, I didn’t have this issue at the other end of the pattern so still not sure why the problem is happening.

Hi Eric,

Try (-1) * StileWidth

Hi Bob3DPO, love the moniker by the way.
Thanks for the suggestion but it didn’t work.

Curious. I use this type of expression often to change sign of value.

It works in other contexts, but wouldn’t work in this particular situation. I must not be understanding all the constraints in place, or perhaps this is a bug.
