Have you ever needed to place a hatch pattern to
reflect the true placement of how the pattern looks like in real life?
The accurate placement of hatch patterns is really quite simple.
Make sure that your USC (User Coordinate
System) is set to World if you are drawing in 2D. Now
simply change the UCS origin to where the hatch pattern should originate
from. Use the UCSICON command and pick the ORigin
option to type in coordinates or pick the origin with your mouse.
A graphic way to see this is to draw a rectangle and set the UCS origin to
the lower left corner of the rectangle. Start
up the Hatch command using ANSI37 as the pattern with an angle of 45.
Pick the rectangle as the Selected Objects
and then OK. The rectangle is now hatched
with the first lower left square aligned with the horizontal and vertical
lines of the rectangle. Zoom into the lower
left corner of the rectangle to show only four
full squares. Now move the UCS origin up and
to the right of the corner, near the middle of the first square and hatch
again. The origin of the hatch now matches
the UCS origin. If you have multiple hatches that need accurate placement,
just continue moving the UCS origin as needed.
By using the first rectangle method, you can determine what the origin
point is graphically for any hatch
pattern. You can then apply the hatch
accurately for your application.
