Re: Voids in Concrete Beams
You have to put the void inside the beam family. Then add parameters so you can flex the size of your void from the project, if that's desirable. You cannot cut beams with voids that are placed in the project environment.
Re: Voids in Concrete Beams
Thanks David for the quick response. I'll head that direction.
Re: Voids in Concrete Beams
nice work dbaldacchino....but if you have many holes...I thing inplace is the solution..
Why is that the penetrations of beams are always perpendicular to the face?
This should be improved..
Re: Voids in Concrete Beams
Mechanical Engineers just love to make you form holes on beams, usually at the last minute on site...
Hey if we all use a BIM system that might not happen!

Add as many holes as necessary in the family and add parameters to control them. If they are the same, array them and then you can control the number of holes too. If you add a parameter for the extrusion lenght of the void you can control which ones are cutting the beam and which ones are not.

Re: Voids in Concrete Beams
The original question was specifically about voids. You cannot do "in-place" and cut a beam like that. You have to locate the void inside the beam family.
A better option to make openings on the fly is by using the new "Opening by Face" tool. Use voids in the family (and perhaps parameterize them) only if you have a lot of repetition, such as if you're creating the same beam over and over and it has the same opening/s, or you're doing a castellated/cellular beam, etc.
Re: Voids in Concrete Beams
I'd agree with Dave. For beams with a "notch" or "ledge" it makes sense to copy and modify the concrete beam family. Although these notches or ledges can only follow the entire profile of the sweep.
On the other hand if you have notches or ledges that do not follow the entire length of the
beam your best bet is the opening by face.
*Autodesk* would be smart to put some work into joining of concrete beams and creating these beam families with notches and ledges out of the box. Since I'm sure everyone is using different parameter names for these.........
Openings are interesting:
If you have a beam and pan joist (and slab) system it would be nice to use the shaft
opening tool for openings. Unfortunately the shaft opening doesn't cut beams. If you
use the opening by face tool, you'll have to have one opening in the face of the slab and
another opening in the face of the slab.....
*Autodesk* would be smart to put some work into the shaft tool to make it cut concrete beams.
Re: Voids in Concrete Beams
Any update on this for 2010?
Or is the only option to deal with setdowns in top of beams to create the void in the family.
Cheers
Re: Voids in Concrete Beams
You can create a beam family that is a void, place this family in your project in the plane you want the void or set down to be and then use the cut geometry tool to cut the beam.
