Void masses are simply voids placed within solid masses, right?

So, for example, if you had a solid sweep with a rectangular profile, a void sweep could be used to remove a chunk of the solid sweep, as long as the void's profile was a subset of the solid's profile, and the void's path fell within the solid's path.

I keep getting an error message saying, "This Mass has no solid geometry for its Void Forms to cut. They must be deleted, or solid geometry added and cut." when I try to use void masses. I must be doing something wrong, but cannot find any clues in the User's Guide or online help.

I am creating the void masses with a tiled screen, so I can see clearly in 3D that they fall within the solids.

Am I missing something obvious?

 Thanks

It is simpole. First draw your solid object. Finish the element. Click on Void Form and creat an intersection object. If you are using the massing tool it should show the void cutting the solid. If not click on Cut Geometry tool. Try something simple and work up to more complex shapes as you get better at it.

Thanks Typhoon, that is exactly how I expect the Void Form command to work, but in my case, it does not. I have a solid sweep, and I'm just trying to cut a hole in it (it is a wall). I would just edit a hole out of the solid sweep's path, but the opening does not extend the full height of the wall, so that won't work.

Robin, I don't see how the Cut Geometry tool is applicable to this task. I am in the Void Extrusion editor, so it is not accessible.

What I have is a battered wall, so the exterior face is raked, interior face is plumb. The bottom of the void sweep is coincedent with the bottom of the solid sweep. Top of the void sweep is lower than the top of the solid sweep, so the void is a subset of the solid.

I am working on a reference plane perpendicular to the sweep, and which intersects it. The depth of the void sweep is such that it falls entirely within the solid. This should be completely straightforward - I am at a complete loss.

Also, Typhoon, can you turn up the gain on your Jing recordings? They are almost impossible to hear with my speakers at full volume.

Thanks, guys.

Okay guys, I found the answer here: http://www.revitcity.com/forums.php?action=viewthread&thread_id=10024

See Post #13. I was trying to create the void as a separate, discrete mass. It has to be created as part of the solid mass. You have to open the solid mass for editing, and create the void in that session, not as a separate mass.

Yeah Sciolist, if you see the video "before" i finished the family i create the "void" then I used the tool "Cut Geometry"... about the "Volume" of the sound, sorry, next time...

Sorry for that man, i don't know if it is my "Microfone", but right now i don't think you can increase the sound because it was "create" with that volume, so even you put your volume in Max. you can't eard much more, sorry...

Today I buy a new one....

Typhoon,

Is there a way to increase the play volume on the Jing files without downloading the software? I was looking for that, but did not see it. Seems like they would have built that into the software, in case gain levels were different on the sender's and reciever's computers.

Pretty cool software, BTW.

Sorry about that.

I was refreshing the forum page as I got email notifications. Guess it doesn't like that.
