PolyU features:
 Mathematical formula curve, 67 kinds of mathematical formulas, can be drawn parametrically and accurately. Such as heartshaped line, orchid line, vine leaf line, etc.
 Image vectorization: change the picture into CAD vector lines, which is very fast and easy to operate.
 Image to holes array painting: convert the picture into shape array in CAD, such as circle, square, diamond, heart, etc. the size and density of shape array will change automatically to form a picture.
 Creative curve  Horizontal Curve influence: use a curve to affect a group of objects, resulting in horizontal displacement or compression.
 Creative curve  create interpolated rectangular array
 Creative curve  random and regular array: offset replication includes random array, half wave array, full wave array, exponential array and logarithmic array
 Creative curve  curve area influence, dynamic click scaling
 Creative curve  Create gradient curves between curves
 Creative curve  Creates a gradient shape between two similar shapes
 Creative curve  Influence curve: control the displacement, scaling, rotation and other deformation of surrounding objects through the curve to create a rhythmic design group.
 Creative curve  Curve quadrilateral mapping: for example, a square pattern can be projected onto a sector, or onto a cylindrical surface.
 Curve Optimization: reduce complexity, increase smoothness, delete duplicate vertices, etc
 Curve conversion: you can convert types between polylines, lofted curves, arcs, circles, and ellipses.
 Fixed number bisection and fixed length bisection curve
 Text to curve
 Draw an associative curve
 Reconstruct the inner and outer contours of the pattern
 Batch draw multiple inner contours and offsets
 Draw the outline of complex graphics
 Batch multiple offset copy
 Curve batch thickening, closing, opening, etc
