Im scaling and extruding a curve and dont understand how the
extrude distance is calculated.
If I draw a curve, extrude by 1, it extrudes by one, in each direction.
If I draw a curve, extrude by 3, it extrudes by three in each direction.
but when I
- draw a default curve.
- scale the curve by n, say 3. I used the key seq s3 and hit enter.
- use cntl-a to apply scale.
- Then extrude by 1. I used the property/data/geometry area that is normally on the right hand side.
- it gets extruded by a factor of 3 times or what ever n was.
Where is this factor coming from. The cntl-a reset the scale factor to 1
I first tried this without applying the scale using the cntl-a incantation.
I figured the scale factor was being applied to the extrude field by magic.
When I applied the scale factor to the object, the scale factor was
reset to 1, as I expected. The internal vertex coordinate now shows a factor
of 3 increase, as I expected. but, the extrude of 1 gives me a extrude of 3.
Now I’m thinking black magic.
I see no place where this is coming from.
There seems to be some hidden history being kept or not cleaned up such that
the scaling history is effecting the extrude amount.
Im new to blender and happy to admit my ignorance but
is this an “operation anomaly” that should be report; and to whom.
can someone reduce my ignorance.
