Sweep around a curve while scaling at the same time?

masterenol — Tue, 15 Aug 2017 22:46:32 GMT

Hello everyone,

In the picture shown below. I have a red circle with radius 10. I wish to sweep this red circle around the white curved line, but I want the radius to approach zero as it reaches the end of the curve.

The object should end up looking like a bull's horn.

Anyone have any ideas on how to go about making this object?

Maybe like this for example,

...from the 3D Modeling Workspace you will find the Sweep command under the drop-down for Extrude o the Home ribbon. Also to be found on the Solid ribbon.

Initiate Sweep

select Mode

select Solid or Surface (Solids are your friend most of the time)

select your starting object profile (must be a closed profile and should be joined as a polyline to become a 3D solid)

select Scale

indicate upscale by 10 or down-scale by .1 (example values depending upon your requirements)

select the path to sweep

All of the select operations are available as alias, select-able from command line, or select-able from a right-click while proceeding through the Sweep command.

Oh yeah, you can always save steps b ypre-selecting the object you will be working with (initial profile in this case).

Hope that helps,

Blaine

How can you make it to where you sweep but it stops straight up at the end, or the circle at the end is at a 90 degree angle
