Wall based family unit problems Hi,
I'm trying to create a family which will be an awning for a wall. I've created it based on a generic wall-based family template. It looks fine in the family unit. However, when I place it in my main model, I go an mistake and it won't place.
If someone could wait at the attached file and explain to me what the problem is I'd profoundly appreciate it.
In general, I can't figure out how to go wall-based families to stick to the face of the wall rather than the heart--this is a longstanding problem for me.
Thanks,
Derek

Re: Wall based family problems Here'due south another version. Looks fine in the family unit. Completely comes autonomously in the project. I tin can't effigy out why.

Re: Wall based family unit problems The Family Editor is like beingness in space, with no gravity. Merely considering it looks similar its on the wall in the family unit editor, doesnt mean itll be on the wall in the project.

Yous have to constrain information technology to the face of the wall, which typically has a reference airplane on it called Wall Edge.
A skillful tip: before you bother loading it in the projection, take the wall in the Family (the generic one) and change its size to a few different sizes. If your family doesnt *move* with the wall to make it correct at different wall sizes, youre going to have trouble in the Project Surround.

Re: Wall based family problems Not simply different sizes of walls tin can be fabricated in the family editor, just you can add layers of materials just like a normal wall. And then you lot can make something stick to the face up of the core or the face up of the end.

Looking breifly at your awning, the sweep that makes up the peak "tube" has the sweep path located on a piece of work plane that is the face of the "core" layer, since your wall has simply i layer currenly in the family editor.

Re: Wall based family bug And so, I need to recreate this family for every wall type that has a different number of layers, so that it's always aligned ot the outer layer?
Attached is wall sconce I created (from the wall-based light fixture family template) which is aligned to the the outer wall reference plane, as described. I can change the wall thickness or type in the family and information technology moves with the face properly. But, again, information technology does not land on the outer wall face in the projection model (whether a simple or multi-layered wall), nor does information technology move with the confront of the wall in when placed on a elementary wall in the project when I alter the simple wall's thickness (despite it performing such a task within the family unit). I'm confused.
Shouldn't this exist a simple thing to get working?

Re: Wall based family unit problems It is elementary. Its non a matter of PLACING it on the outside of the wall, its a matter of CONSTRAINING information technology there. Thats why i say change the wall size a few times. When you make a hosted family, it should piece of work correctly regardless of the size of the host. If information technology doesnt, youre going to take troubles.

Attached is wall sconce I created (from the wall-based light fixture family unit template) which is aligned to the the outer wall reference aeroplane, every bit described. I tin can change the wall thickness or type in the family and it moves with the face properly. But, again, it does not land on the outer wall confront in the project model (whether a simple or multi-layered wall), nor does it move with the face of the wall in when placed on a uncomplicated wall in the projection when I change the simple wall's thickness (despite it performing such a task within the family).

Dimensions, or alignments, tin be locked to the reference plane chosen Wall Face. When stuff isnt constrained, Gravity gets you.

Re: Wall based family unit problems I hear/capeesh what you lot're saying...it makes sense....thought I'd done that.

Re: Wall based family problems The trick I used
is to nest another family into the wall based i.This fashion the imported object will move all at once,
even if you just constrain one edge past aligning it
to the face up of the wall.if you change the wall blazon in the project,
or testing the width in the family every bit suggested,
the fixture (in my case) moves appropriately.Stefano
