Would like to create shop drawings for a steel fabricator.  Various pieces of steel are fabricated seperately and then bolted together in the field - pretty common.

Lets say I have four different pieces which all get bolted together.  Therefor the hole (location and size) needs to align and be in the same place for all four pieces.  In addition to wanting to do this, I would also like to isolate each piece seperately to make a cut sheet for each individual piece - showing the void location!

How should I go about this?  How do I get one void to pass through different families?  Then how would I isolate each individual piece (family) - with the void cut out, to create a cut sheet? From what I can tell, I can't create a sheet within the individual family.  Nor when I bring in a family into another, I can't use the void form to cut through the imported family - it only cuts through the primary or host family.

Hope that all makes sense...thanks for you help

In your family create 4 individual Object Styles, create each steel plate on a different sub-categories, create a single void thru all steel plates.

Load your family into your project, create 4 different views of your family, turn off the un wanted sub-categories in each view leaving you with 4 different views of the 4 different steel plates. Then dimension individually.

Best of luck

thanks john,

that sounds like it will work.  but how do you creat a sub catagory?  I see it in the properties, but it just gives me the option of none or hidden line.  I understand the concept, how do I actually do it.

thanks

I think I figured out the subcatagory issue.

But lets same I have all thes pieces some built together in one family loaded into one project.  Would not all the elements be in the generic model catagory, and thus I have all these pieces.  is there a way to group them say as...an assembly?

thanks

They are all based under the family category that you used to create the object eg Generic. You should create sub-categories under the major category by going to Object Styles (in the Family) and create new sub categories of your own selection.

Then after reloading the Family back into the project, go to Visability/Graphic go to the main heading eg Generic Models and you will find your sub-categories listed. You can then turn each one on & off within each view.

Note that after you create the sub-category you will need to select the items you require on a sub-category then go to properties select the sub-category box and select the sub-category you want that/those objects on.

Best of luck

thanks John,

question/example

lets say i have 20 different "assemblies" or single families loaded into the project, each one has 4 seperate pieces of steel as their own seperate sub-catagory.  I have been building these under generic models.  If I do this, and I am doing this correctly, I will have 80 different subcatagories which need to be turned off and on for each particular view.  Is there a way I can group them, so or can the collection of 4 plates, one thing and then just turn off that one "group" so to speak.  otherwise I need to back and turn off 79 pieces (assuming they are in the same view) just to isolate one.

hope that makes sense.

thanks again.

If your using 2008 you can select any or all families right click your mouse and select hide, this works on a view only basis.

Maybe you can reduce the number of visable families by using your crop regions

You can modify families to have a On/Off switch that turns the visability of any model item within that family on or off. But this must be done tho all families that you wish not to see.

Note that I made the same 4 sub-categories in all 20 families (say 1 2 3 4) and turned of 1 2 & 3 only 20 items would be visable.

Hope this helps
