How to Put Holes in a Wipeout? Letting objects behind show through.

[SundayST]

I am trying to use the WIPEOUT command to make one object that is in front of another one obscure the one behind it. I have my polyline drawn around the object in question, but I need for things to show through the object where there are holes in the object.

 

In my specific example, I have a tree. I need three trees in front of one another and some against a wall. I would like for the wall to show through between the branches of the tree. I would like pieces of the trees in the background to show through between the branches of the tree in the foreground. So there are multiple holes in the foreground tree because the leaves and branches are not one solid object. Is this possible?

 

A more simple example would be if there was an object with only one hole in it...such as a door with a window through it...could the wipeout apply to the door - but still show through the wall or scenery behind that door only where the window is.

 

Please help. I am not an expert at this by any means, and this is my first foray into using Wipeout at all. Prior to a day ago, I had not even heard of it. (The trees prompted me to find out about it in the first place. My only other solution is to explode the trees in the background and trim off pieces that shouldn't show. There are a total of thirteen trees in my drawing. This would take a LONG time.)

 

Thank you for any assistance you can offer!

That's not really what wipeout was intended for. I've never tried it, putting holes in one, that is.

 

Say you have three trees that overlap. Why does Draw Order not work for you. tree 1 = send to front, tree 3 = send to back, and tree 2 is left alone to find itself in the middle.

 

Maybe you should look into the solid fill stuff in the hatch options too.

Assuming that you use CTB plot styles, instead of using WIPEOUT use a HATCH instead. Create the boundaries you need, then HATCH it using the Solid hatch style. Select the hatch, then use True Color and set it to 255,255,255 (in other words, the RGB true color for White). This will act as a "mask" since paper is white, and so it simply blanks it out.

 

If you use STB plot styles, just simply create a plot style with a 0% screening.

One of the things that happens with 2d is if there all on the same plane stuff will disapear a window drawn on a wall hatch may disapear, quick fix to try wall elev 0 tree1 Z 0.01 tree 2 Z 0.02 tree3 Z 0.03 move pick ob 0,0,0 0,0,0.01

 

this use of z can be used in conjunction with wipeouts to block stuff out but show something else

Hi, I make it as it's shown on image. Start to make a wipeout in order of points 1,2,3,4,5,6,7,8,5,4 and close for that example. Then if I need, set up the IMAGEFRAME to 0 to make the frame invisible

 

sorry for my english
