Revision Cloud

[rhayes.99001]

Anyone know how to draw revision clouds in a straight line? So you don’t have your hold your mouse ever so lightly and cloud a large area?

[Steve_Bennett]

Make a rectangle & use the command line option to convert a object to the rev cloud. (or any closed polyline)

Make a rectangle & use the command line option to convert a object to the rev cloud. (or any closed polyline)

This was one of my favorite improvements in 2005. I love being able to draw a pline, and covert it to a revcloud, and even have the option to flip direction. It's great.

THE FOLLOWING SHOULD CREATE A RECT CLOUD:

Great tip! Thanks!

[dgonzales]

New issue with this is that in the 2010 MEP version, you can no longer create a rectangular polyline and convert it to a cloud. Unless I'm missing something and not realizing how to now change a polyline to a cloud please can someone help me?

[dzatto]

Draw a rectangle, then type REVCLOUD , enter, then O, enter. It should let you pick the rectangle.

If the radii of the cloud arcs is too large, it won't let you. So if it does't work, type A instead of O and change (or check) the size of the arcs.

Hi there, I have a question. Is there any standard method to draw hold cloud?

I know we all use the same method to draw revision cloud but my consultant use cloud in reverse direction for hold cloud, and they claimed it is international standard. I try to search but I cannot find any international standard saying that we should draw hold cloud in reverse direction. Can anyone advice me on this issue?

You can also use the left mouse button to pick points rather than just hover.
