transparency/ opaque 2004

[Dan]

I am new to 2004 and am trying to use the new features without much look! couls someone explain how the wipeout command works, i hav elloked under help - but it wasnt much>


I understand that AutoCAD 2004 has a transparency tool. I need to be able to make solid hatches and other hatches opaque or transparent - as can be done in photoshop under the layer, transparency tool. - Any ideas?? I appreciate you could use a dotted hatch but this does not give the desired effect.

Thanks for any ideas you may have.

Heres how Ellen Finkelstein runs you through the wipeout command
To create a wipeout:

1. Select Draw > Wipeout from the AutoCAD main menu.

2. At the Specify first point or [Frames/Polyline] <Polyline>: prompt, specify the first point of a polygonal shape to cover existing objects. To use an existing polyline, right-click and choose Polyline. Then select the polyline and choose whether to erase the polyline. (The polyline must be closed, made up of line segments only—no arcs—and have a zero width.)

3. At the Specify next point or [Undo]: prompt, if you specified a point, specify the next point.

4. At the Specify next point or [Close/Undo]: prompt, specify another point or use the Close option to close the wipeout shape. Continue to specify points until you have the shape you want. You can also press Enter to end the command.

By default, the wipeout has a frame around it, using the current layer’s color. You can hide the frames of all wipeouts. Start the WIPEOUT command, choose the Frames option, and choose Off.

A Wipeout object functions like a raster image, so it has the same requirements for plotting that raster images have—you need a raster-capable plotter with a suitable driver. You may also have problems using wipeouts on a model layout in 3D drawings, but they work fine on a paper space layout.

With SHADEMODE you can have transparent Gourouad (spelling ?) edges on and you can see objects behind one another. It's cool.

Dan, sadly, you are misinformed. AutoCAD 2004 does not allow transparency/opacity control over objects (if only it did!!!). What is new to 2004 is the ability to make some of the palettes transparent. Even this isn't implemented consistently. The palette you really want to have transparency control over, the Properties palette, does not have this facility.

Opacity control of objects/layers in AutoCAD would be fantastic and would completely change the way it is used. Just imagine the possibilities for the presentation of complex design drawings. Unfortunately, that's all we can do at the moment... Imagine.

I presume you know that you can have a transparent material applied to an object ? see a 3do orbit with transp. material here



This can then be shown whilst editing live and visible as you
move an object in 3D orbit ?

I'll post up how to do this in Autocad2000i or greater if req'd.

I run win95 and have a Pii 266. As long as the model is small it's cool .

Transparent materials are one thing, transparent objects - that's the holy grail. I doubt we are likely to see this sort of control in AutoCAD any time soon.

My pic does show transparency. Also 2004 will show transparent objects when in SHADEMODE, inlcuding in 3do etc.

Yes Nick, I know but that's not what Dan asked about. Read the top of this thread. Tell me you can control the transparency of hatches at any given percentage and I'll start to take notice.

You never know David, we finally got gradient fills. Maybe better items are to come....well, we can hope they are

A solid hatch in 2004 within a viewport may not be transparent but within viewports in layouts you can have a transparent SHADED view. A solid shade with a transparent opaque tweak ?

Basically a hatch area, in 2D, is actually a region. Regions can be filled/rendered with a transparent material. Then add that material to a tool pallette and hey presto just drag n drop it on whatever area you wish to hatch !

I will double check the exact specific thread question tomorrow at my school Acad2004.

In the meantime if Express tools are installed try the SUPERHATCH
command.
