Trim Block

[beavis123]

Hi-

I am working on a side view in which I lay blocks of several side view components in close proximatey. Usually I wind up exploding the blocks and trimming away the necessary lines in order to get a true representation of how the assembly would look when viewed from the side. There's got to be a better way to trim the blocks without: editing the original block or exploding. TY in advance for any and all comments:oops:

Does 2002 have a Wipeout command? From the Help files:

 

"A wipeout object is a polygonal area that masks underlying objects with the current background color. This area is bounded by the wipeout frame, which you can turn on for editing and turn off for plotting."

I am using 2006 and I have wipeout, but I would have to draw a lot of rectangles to cover up all the pieces. I seem to recall some block edge edit command that would trim the lines without killing the block. I just can't seem to recall it...i appreciate your reply

Block edge edit command? That's a new one on me. There could very well be a command like that...I just haven't come across it.

Express Tools > ClipIt. Would that work?

I believe block edge allows you to use the lines within blocks as trim edges, so while you can trim a line that extends beyond the block, you can't trim the block itself. Perhaps you might want to consider delving into the world of dynamic blocks? They are wonderful for condensing block libraries. If you post an example of the trim block I can throw some parameters on it to help explain the concept.

How can I attach an example?

[MaxwellEdison]

Select the block and use the WBLOCK command. Specify the path and filename and voila! Your block is a seperate file.

Drawing "example" attached.....I hope.

Okay, block looks good (FYI the wipeout wasn't obscuring the screw because it was not over it, turn wipeout frames on WIPEOUT->F->ON to see what I mean). What would the blocks need to do if they were all combined into one?

Handy little command for trimming blocks. I've used it for quite some time, with great results.

I may need to place a smilar block in front of the original. Doing so will obscure certain planes of view, i.e. some of the exisiting lines will then become blocked out (hidden).

[MaxwellEdison]

Is this all being done in 2006 or later?

Won't that update the block definition?

[beavis123]

yes all in 2006

I think the easiest thing for your situation would be to include the wipeouts in the block themselves. I've attached your file to which I've added the wipeouts. Try changing the draw order on the objects and see if they respond like you wanted, I think they will. Frames are left on for the wipeouts so you can see them and mess with them in the block editor. See my previous post on how to toggle them on and off.

You can Use XCLIP command to trim Blocks.

XCLIP ---> Select the External Block in the view--->Enter---> Select the New Boundary---> Select Polyline or Rectangle:)
