Can't Move Sweep

Can't Move Sweep

I have a Sweep which was created in Elevation in the Lower Right quadrant. If I Move or Copy it above the X-axis, the Sweep fails and can't be created. If I Move or Copy the Extrusion used to create the Sweep to the First quadrant, the Sweep can't be created.

 

What is wrong??? This is very frustrating and happens with any release of Revit I've tried.

Can you post the family?

Here's the Family - I was able to move the Sweep once I deleted other objects in the file, but they weren't joined and nowhere near it. I still can't get the Joins to work. 

 

Something so simple is so hard. Basic modeling really needs to be reviewed...

The sweep joins with an extrusion.  Keep them joined then you can only move it in one direction.  Unjoin them and you can move it in any directions.

 Take a look at the screencast. I’m getting three conditions here, doesn’t matter if the objects are joined or not, same thing in the front and side elev.

  1. working fine, sweep is visible when moving
  2. doesn’t work, sweep disappears
  3. doesn’t work, sweep is partially visible (????)

Weird. I’m not sure what’s going on, but I’d suggest building the back rest as a separate family and nest it into you chair family.

Thanks - it's really bizarre as you can see. I had other objects in the Family and before removing them, I couldn't Move the backrest at all. 

 

I've spent hours trying to figure out what I did wrong, so it doesn't happen again. I'm still baffled.

I was able to move it after I recreated the sweep.  But who knows when it's going to break again so I too agree it's better be a nested family.

@davidwilliamedwards Yeah, me too. I’ve tried fresh furniture and generic model families with the same results. A bug?

@ToanDN I’ve tried that too. It didn’t work for me.

It appears that the issue was with how I was creating the Sweep. For many more complex "moves", I'll creating a 3D view. For some reason, this didn't work with this curve. When I tried to create it in Elevation views, it worked. Don't know what would make the difference, but I must have tried a bunch of different things. Getting this working consistently helps in the long run.

@davidwilliamedwards: My goto solution in such cases: path sweep along a model line that is aligned and locked to extrusion: edge -- rather than pathing the sweep along extrusion: edge.   

 

...dare you to pull on the extrusion's grips in the attached rfa and try to break the sweep.

Still broken I guess.

HA! Thanks a lot Toan! You must be stronger than me. Oh well...good for you Smiley (fröhlich)

 

 

p.s. ...HEY! I said pull on the extrusion grips and try to break it! Since the extrusion's 2D profile and the sweep's 3D Edge are not co-planar, I'm not surprised by this result.

@ToanDN Here. Try this one.

 

I'm surprised no one mentioned "Nesting".

 

@davidwilliamedwards: Another goto soluton I use in such cases: break the family up into nested components. Personally, I would do this just to remove all the Warnings from the Parent Family. The seat cushion is loaded with them.

@barthbradley

 

Both @PijPiwo and I did recommend to use a nested family for the backrest.

Well, that settles it: it's time for a new eye-glass prescription for me

 

In any case, that's a great suggestion by you, @ToanDN and @PijPiwo. If this was my thread, I'd give you both credit for the solution and many kudos, because, from my experience, that's a most effective solution -- and a smart way to build families. 

 

 

...or you could just download a chair family from here, and save yourself the hassle:

Not the gig - I wish it was that easy.
