Local Extrude Edge translate Y bug !

[smoluck]

I do a little tweak to bypass that problems, but It can be usefull to know how using the Extrude Edge Local translate because I've got a tweaks for that type of problem, but It can be very difficult to fix in another condition.

that's for Road modeling so I've not complex shape curves , topology. So I dicided to Select the Exterior loop of my shape by using Selection / Select continuous edges.
Extrude edge with Global Translate Y up by X value.
grow and convert selection to face.
Extrude Face by using a local Translate Z with a value of 3.5 Metre (in my case)
Delete that new bunch of face , and delete the garbage face shell up.
Now That's good. But it's an exception because I can do an Extrude edge Global Y up. In another condition, I couldn't fix that Extrude Edge Local Translate (Flipped bug) error.

do you know how to fix that tool bug ?

The Only Problem With My tweaks was that; when you do a standar extrude edge (in local when it works ^^) your new created faces as good squared UV's, But In my tweaks that face are created by an extrude edge so there UV's are Flat and in line :sad:. So I need to have some more work on UV because I know that the Normalize UV's will do many rotated UV's as I won't.

So I need to Select borderline Edge (select continuous edge), convert selection to Uv's, and apply a polyEditUV -u 0 -v 1; to move up these UV's and Correct that problem:thumbsup:
