Sweep Error Code Number #55000

[edwardlim8]

I have a 3D Polyline and a circle(radius = 9). I need to use circle to sweep along 3D Polyline path, but I get an Error Code#55000.

However if circle radius >= 9.7, it works.

May I know why there is difference between circle radius 9 and 9.7?

Bellow is my 3D Polyline coordinate:

X,Y,Z
3307.8465,166.9,228.6

@edwardlim8 ,

Posting your drawing will increase your chances obtaining a solution.

Provide the version of AutoCAD?

@edwardlim8,

FYI - I was able to generate your 3D Polyline Coordinates and SWEEP a circle of Radius 9, without any errors.

My AutoCAD Version is 2019

Below is my drawing. Thanks a lot for your help!

@edwardlim8 ,

To resolve your issue, SWEEP from the other end of the 3DPolyline.

Follow these instruction:

• Copy the 3DPolyline to the side.
• Draw a circle, say of Radius 35.
• Sweep along 3DPolyline
• Type UCS and select Face

• Select the end face of the circle and accept. (Take notice of the X,Y,Z)

• Draw a circle with Radius of 9 and SWEEP.

Thank you very much for your help! Your method works.
And from the solution you provided, I am wondering that when I draw a 3D Polyline, If I start drawing from the end to starting point, I can use SWEEP directly!

But I'm still very curious about why SWEEP can't be used directly but need other methods
