How can one draw a parabola within Revit?

[ro]

Is there a way to draw a parabola within Revit, without using Dynamo? "No" is an acceptable solution.

At first I was going to suggest using the spline thru points, which would be a bit tiresome as you would need to calculate the points and place a bunch of reference planes. Then I did a quick search and found these two links (one not ADSK forum, sorry)

Google "How can one draw a parabola within Revit?".  You'll get a half-dozen or more hits of tutorials.

I tried an internet search before starting here.

I can see Dynamo solutions and I can see fragmented, laborious approximations but not how to draw a pure porabola in Revit.

Ultimately it's a formula (any) that is drawn.

Thanks again @barthbradley . I have done that search (I use duckduckgo but tried google for laffs). I can't see any relevant results, hence this forum post.

Use Generic Model Adaptive family, add ref point and set their location using parameters (driven by a parabolic formula), then select the points and create a curve through points.

I'm not following you. I posted above an actual link to a video tutorial showing how to make a parabola in Revit. Is that not satisfactory?

Thanks @barthbradley . When I do that search I see a range of hyperbolic surface but not parabolas. Could be a google issue at my end.

thanks @ToanDN . Sound promising. Will road test this in a couple of hours.

Post a picture of the parabola-shaped construct that you are wanting to model in Revit.

Hi @ToanDN . This isn't too bad but, the resolution is determined by the number of points you create. And the shape is a series of splines. Is that correct?

[Tom_Kunsman]

Yes, the resolution would be determined by the number of points. The more points the smoother the curve will get.

Barth, every time I open a thread on the Autodesk forums, I see you making snide remarks under someone's post. You need to save the condescension for your Reddit account and work on your civility.
