If it isn't one thing, it's another.  I downloaded this double hung double window.  The mullions only show on one side in 3D.  They show fine in 2D.  I don't know what to do to the family to make it work.  See attached JPEG and the Family file.  Anyone have any idea?

Thanks so much.

Could Be:

1.Open the family and click the mullions that are displaying correctly. On the Ribbon go to Modify Tab, then the Mode Section and click on the visibility settings. Check that these are all turned off.

or

2. In your Project file go to the 3D view and click the Reveal Hidden Elements ( light globe in bottom left corner) this will turn on everything that was previously selected and hidden. See if the mullions show up in red if they do, select them and right click and unhide them.

or

3.

Open the family and check the mullions are in the family. If they are only displaying in 2D this may mean they are modelled in 3D but in elevation the 3D mullion is hidden and 2D lines are drawn in their place ( this is done to speed up the regeneration time)

Try these and lets see how you go.

Thank you for helping.  Sorry, none of those suggestions worked.  Dang it.

I went back into the family.  The mullions are extruded objects.  I edited the extrusion and in that editor, I copied them over to the other panel.  We now that screws things up.

See attached.  The family looks perfect, both 3D and 2D.  I am so excited.  Went to load into my project.  No go!  Huge nasty error.

Sigh**** now what?

The original family had only 2d linework on the right hand side (delete the linework and you will see there is no extrusion under it) which is why it only showed in 2d.  THe left hand side had both 3d extrusions and 2d linework so it showed in both.

I would guess your issue is that if you simply copied the extrusion over to the other side there is a good chance that all of the locks and references/dimensions in place for the mullions were broken and as such when you load it to your project it tries to adapt to the model and cannot.

Instead of copying the extrusion, create a new one for the left hand side and ensure you lock it to the reference planes to control the size so it can adapt to your model (mimick the locks on the left hand side that appear when you select the extrusion on the left). 

Good luck

Here, I have created the 3D mullions for you in case you are dsperate and dont have family making experience. When using someone elses family it can tricky understanding what all the dimensions and reference planes are to be used for but I have this working and it adjusts both height and width for me in both the family and when loaded into a project so it should adapt to your project.

If you want to know exactly what I did, I created new extrusions and locked them to the reference planes with the dimensions as per the left hand side and then reset some equal parameters that appeared to break.  I also assigned the same material parameters as the left side.  Tested in family, loaded to project and tested there, works for me!

Good luck

OMG!! Thank you Rudyard!  That is great!  Families are my next big hurdle for sure.  I just haven't had the time yet or a good concise video or tutorial specific enough or advanced enough to get through that task. Sigh.  I did by the month subscription to Lynda.com, not looked through there yet.

Thanks for the window!
