Create a curve from a library
of pre-drawn curves (sweeps)
The
Sweeps tool lets you create a curve by pulling a curve from a curve
library and transforming and trimming it.
The Sweeps tool is designed
for use as part of a workflow: pick the curve from the library, transform
it into place, trim it to the section you want, and set its pivot
point. The user interface of the tool is optimized for these steps.
Create a curve from a sweeps
library
- Choose Curves > Primitives > Sweeps
❒.
- The sweeps window has two tabs for a
standard (site-wide) library and your own (user-defined) library.
Click a sweep displayed in one of the tabs.
- Click in a view window to place the curve.
- Do any of the following:
- Click Transform and
use the transform manipulator to move, rotate, or scale the curve.
- Click Trim to trim
the curve (see below).
- Click Pivot to
move the curve’s pivot point (same as using the Transform > Local > Set Pivot
).
- Click Create to
create another curve using the selected library sweep.
Trim the curve
- While using the Sweeps tool,
click Trim.
- Click to place manipulators at the start
and end points of the section you want to keep.
- A red arrow indicates which part of the
curve will be kept. Click the other part of the curve to switch
the red arrow.
- Click Go to trim
the curve, or click Transform, Pivot, Create,
or another tool to cancel the trim.
