loft/sweep

PaulTolliday

Hi I am trying to do something that i thought would be very simple, what i want to do is create a curve / spline and place a square at each end perpendicular to the line, dimension each square for example 1st one is 50mm X 50mm and other one is 100mm X 100mm and then sweep along line from 1st to 2nd square so i get a curved solid that tapers down in size. something i would have thought is very easy ?

Hello.

The task should be possible by using the LOFT command.
The 2 squares should be selected as cross sections.
Then, the Path option should be used and the spline should be selected as path.

An approach could be to use the CV method to create the spline.
This would make it possible to use a polyline (2D or 3D) as a construction base, and build the spline using the vertices of the polyline.
Having a construction base would also help to place the squares perpendicular to the spline.

Something to pay attention to is the curvature of the spline.
If there are areas of the spline where the curvature is too tight, the result of lofting would be a self-intersecting solid.
In this case, the operation will fail.
