Gradient Hatching @ angles

[Glenn Pope]

I've been messing with the gradient hatching trying to make a shadow effect. When I change the angle of the hatch to any thing other then 0° or 90°, the hatching comes out looking solid. Has anyone else experienced this?

Glen,

When you are in the Boundary Hatch Dialog,
working on the Gradient Tab, are you modifying
the Angle value to be at or near the angle of the
area or the direction of the shadow you attempting
to approximate? It is just below the Centered toggle
and just above the OK button.

[Glenn Pope]

Yes I am. In the image I attached, each rectangle are placed every 15°. Each hatch is set to the same angle. So they should all look like the first and last rectangle.

Hi

Have a read of the following -

AutoCAD 2004 Multiple Hatch Transition (http://discussion.autodesk.com/thread.jspa?messageID=4515)

+

Please take a look at the attached drawing file (just to see if I've understood correctly).

Have a good one, Mike

[Glenn Pope]

You got it.

This seems like a bug, according to your link. It seems that the hatch creates a boundary around the rectangle, calculates the transition of the color, then trims to fit the rectangle. So its basing the transition on a larger area then what you want hatched:mad:

Creating a block seems to be the only work around.

Any idea if this was fixed in 2006?

appears to be....

first group was created using a single hatch, second was all selected and creating separate hatches...

Thanks Mel....anie. :p

Still doesn't look right. Could you try duplicating the image in my first post? Making the color with blue on top and white on bottom and rotation every 15%%d.

alright, blue on top, white on bottom...

[Glenn Pope]

alright, blue on top, white on bottom...When you hatched each rectangle, did you change the hatch rotation to match the rotation of the rectangle?

To make it look like this.

um, no. this is starting to sound too much like work...

um, D'OH, that's not good... same as the old way, so, no, it isn't fixed. lol. sorry, I'm a little slow...

okay, the set on the left is drawn as you've said, then I took the straight one and rotated and arrayed it just for kicks...

Thank you for smashing my hopes and dreams :wink:

But seriously, Thanks for looking into this.

no problem... ;) always good to have practice doing that...

curious, how will you be using something like this?

I end up doing a lot of presentation work for projects. Have to show citizens how after we are done ripping throw their front yard and destroy everything, that it will look great when its done. So this has come up a couple of times. Mainly when doing shadow effects.
