I'm doing a floor hosted family using the floor hosted family template. It workd well for some of my family types, but it has a floor opening in it, for a specific type it grows beyond the edge of the generic floor and it gives me all sorts of errors.

The template has a generic floor mass in it, that is too small!!! I do not see any <edit> button or anything, even the size properties are locked!

Is there a way of growing/scaling/streching it?

Your opening is allowed to exceed the floor, the floor is just in there so that you can "see" what you are doing.  If you are having problems with a particular type, try the following, when making your parametric families, make reference planes first, dimension them, do their parameters, etc.  then "flex" your model, ensuring it behaves properly.  Once it works right, then add in reference lines (if you need them) or model/symbolic lines/geometry.  The number one error that I find where I'm working is that users constrain something to the "flesh" of the model (geometry, lines, etc.) instead of the "bones" (ref planes, ref lines).  Using my analogy above, if you try to "flex" the model, if it is dimensioned to the "flesh" then it might rip off.  If dimensioned to the "bones" it will produce an "error" if it can't be flexed in that manner, but won't be "ripped" off.  Hope this helps.

Well, I created the family that way, using parameters attached to reference planes and then attaching all the solids and openings to them. (Must have screwed it somewhere).

Let me try your method using a blank template and test it for weirdness...

thanks.

Thanks,

I revised my family -like you said- and it had 2 symbolic lines attached to objects instead of reference planes (they were overlapping). Fixed that

I got the <Opening is not cutting anything> error, but just ignored it...

Worked perfectly!

How would you modify a family from face-based or hosted to one that is not?
