Create Sweep Along Varying Plan Profiles

Hi All,

 

I am trying to recreate the following crosshead.

Is it possible to create a sweep of the vertical profile (orange line) which follows the (horizontal) profiles at the varying heights?

Is there any other way to create this profile, I am struggling.

 

Thanks.

Model the form then create a sweep using pick path.

Hi ToanDN,

 

Please correct me if I'm wrong, but I believe the problem I have is that the profile form (orange) needs to adjust as it sweeps around the varying profile shapes (see screenshot below)… I'm new to Revit, but I don't think this is possible?

Sure it is possible. Share that file you are working on.

Sorry ToanDN,

 

I accidently left reference lines following the same profile as the very top plan profile; you can delete these reference lines if you like.

It's a tough one but can be done.

I am after this shape (this is the original design file).

Looks like the one I did above.  Is this what you are trying to do? Sweep a Profile along your Form like I did here with a circular profile?

Hi @barthbradley,

 

No, I am trying to recreate the original shape (I don't want to add additional shapes like you have with the circular profile).

Holy cow! That's it?  Just select all the stacked profiles and press Create Form. Bada bing!

That doesn't work for me because it ignores the curvature of the edges (see screenshot, circled).

Okay, I see now.  You want to reproduce what you have.  Well. first off; what's the game plan? Where are you going with it afterwards?  

 

Anyways, you can reproduce the Form, but it'll take some work.  The first thing I would do is create a bunch of levels.  Then I'd draw a Profile on each Level.  Then I'd select multiple Profile and press Create Form.  In order to  draw the Profile on each Level , I would need to have a way to trace (via Pick Lines) the existing Form's shape at that Level. To be able to do this, I would intersect the existing Form with a Void at that Level, draw the Profile using Pick Line method, uncut the Void, resize it to the next Level and Cut again and then draw the Profile at that Level via Pick Lines method.  Rinse and repeat for each Level.

You can fine-tune the Form created by selecting Form, activating X-Ray Mode and adding additional Profile via Add Profile, and then reshape the Profile as necessary to "correct" the Form's overall shape.

Where did you get the original freeform from?
