If you read CAD Notes tutorial on dynamic block, we use wipeout to automatically ‘trim’ objects. Very useful for placing door on a wall or schematic drawings.
However, wipeout has a downside. Some people reporting that wipeout won’t plot correctly on some plotters or to pdf format. I tried it, and don’t have any problem with wipeout. But if you have the problem, then what else can you use to do that trick? We can use solid hatch!
You can try to activate hatch, then select solid pattern. Then in color selection, you can choose the color to white. But where is the white color?
White color is not available in indexed color. Click the color list then choose select color.
Now you can see that default color is indexed color… and it has no white. But if you go to true color, you can find the white color. Move the luminance slider to the top or change the value to 100. You will get white or 255,255,255.
Now you can use it to mask object beneath your object.
Do you know that you can also have background color for hatch? This only available for pattern. You can mask object below your hatch, and show it more clearly.
If you still have problem with plotting hatch masking in pdf, you can see the explanation of ‘streak’ in here.
