PromptForFamilyInstancePlacement problem

[bcampbell11]

I am trying to insert a family using the following:

uiDoc.PromptForFamilyInstancePlacement(famSym)

this works about 85% of the time.  My current problem is that it will work great for the "K-Series Bar Joist-Section.rfa" family for most sizes but not all.  For example the 16K2 produces the attached error, which says "the command to place an instance of this family is disabled".  But why wil it work with most of the other types in the family?

Any ideas?

Thanks

by the way, trying to insert the same family via the doc.Create.NewFamilyInstance(Point, famSym, doc.ActiveView) way, it acts like it is placing the 16K2, but then there is nothing actually placed.  Again, most of the other sizes insert just fine.  This is very random and just about all of our families have a couple of "rebel" familysymbols that refuse to work.  I am stuck on this one...

Thats odd and I don't have an answer for you but....

Have you tried using

ActiveUIDocument.PostRequestForElementTypePlacement(ele)

Maybe it mat behave better.

Phillip,

Thanks so much for the reply, but I figured out the problem.  I was failing to consider including the familyname in the program when I inserted the symbol.  So if there was already a symbol with that name but from a different family, it wouldn't work.  So, I guess you could call it a rookie mistake.

Thank you!
