Wall based Family templates - Placement Side confusion

440 Views, 4 Replies

When i start a new wallbased family from any of the provided wallbased templates (metric), i find it very confusing that the "placement" side i shown as the "back" side on the 3D viewcube when in a 3d-view.

-

Also - when you create an extrusion directly on the placement side in the placement-elevation view, it extrudes backwards "into" the wall, unless you give the extrusion a negative value (?).

-

Seems as if somethings has been flipped incorrectly or am i missing something completely here?

-

(Some of the older updated families like the wallbased "3d-urinal", doesnt have this flipped placement side)

-

Can anybody enlighten me on this issue ....?

Why aren't the Autodesk gurus responding to this one?  I agree entirely with everything that has been said by you since I get totally confused by this issue also.  Intuitively the Placement Side is the side that you are applying the object to so that anything proud of that surface should have a positive value.

Lets hope someone replies soon!

Over two months later and still no response!  Why?  Another related issue is the subject of wall based light fittings, which compounds the confusion since the template shows the 'light source' on the 'placement side' which makes sense and seems to justify the previous posts?

The wall-based family works as "expected" only when you place the family in a floor plan view. But, most of the times, we need to place the wall-based family in elevation view. This is the case when it does not work as we expect. But, knowing this behaviour, if we know that the family will be placed most of the times from an elevation view, it is better to place the object in the family on the opposite side of  the "placement side".

 

Anyway, to make things easier, put a "double vertical" control in the family. With this control, if the family comes on the wrong face, you can flip it easily to the opposite face.

When you're working with reference planes, the factor that decides which direction is positive and which direction is negative is actually the direction in which the reference plane was drawn (i.e. right-to-left or top-to-bottom).

 

If you draw the ref. plane left-to-right, then create a positive extrusion in the placement side elevation, it will extrude toward you.  If you draw the ref. plane right-to-left, then create a positive value extrusion in the placement side elevation, it will extrude away from you.  See image.

My guess is that whoever created the initial wall-based family template drew the reference plane that is aligned with the face of the wall from right-to-left, so extrusions made in the placement side elevation get extruded away from you with a positive value.  Just create a new reference plan to define the face of the wall, align/lock it with the face of the wall, and you're good to go.

 

Doesn't excuse whoever set it up that way to begin with, but the developers seem to be fond of the plan-north side of families being the working point/view, and with drawing things counterclockwise.  Their may be a reason for it, but I haven't figured it out, and it's contrary to the way it should be, but that's just a personal preference, and it hasn't slowed me down yet.
