Learn to create tubes and sweep sketches along guides in Siemens nx unigraphics, adjust outer and inner diameters, and use offsets and boolean operations to build solids.

Explore how to create linear patterns in NX using the pattern feature, including direction control, count and pitch, span, two-direction symmetry, and pattern increment.

Create a circular pattern by selecting the circular layout and the base feature, then define angular count, pitch, and the rotational axis around the center; optionally add concentric rows.

Create polygon patterns with a specified number of sides and axis, then explore concentric, spiral, long, and reference patterns to propagate edits across patterns.
