I want to make a pair of handlebars, now in Anim8or this is relatively easy as all I need to do
is create a spline path shaped to the dimensions I require.
Create a cylinder, then use a script to make the tube follow that path.
Add a curve for the shape of the handlebars and another circle/curve for the cross section, then use the cross section curve as the Bevel Object for the first curve.
If the cross section is circular you could instead of using the cross section curve, increase the bevel depth of the curve with the cross section fill set to ‘Full’
Alternatively you could use an Array modifier followed by a Curve modifier to enable a mesh object to be swept allong the curve
