Poly-U features:

• Mathematical formula curve, 67 kinds of mathematical formulas, can be drawn parametrically and accurately. Such as heart-shaped 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
