Curve tools

Some lines need to curve, and in this section, we deal only with curves of various types. To get your curve right, you can click on the line and drag it around to get close to what you require and there are 'handles' that you can click and drag around until you get the right shape that you're looking for, or you can use exact degrees.

Important note:

The direction of the curves ist shown by arrows on the curved line. This is important when you want to create a new pattern piece.

Curve - Interactive (Shortcut Alt+C)

Create a curve between two nodes
Click on the first and second node. You may now drag the handles around to make the curve more pleasing or use direction and angle formulas to get a more precise curve
  • Name: Name of the new node
  • First point: Starting point of curve
  • Second point: Endpoint of curve
  • First point handle - Lenght: You can define a fixed lenght or use formulas for adaptive / calculated values
  • First point handle - Angle: You can define a fixed angle or use formulas for adaptive / calculated values
  • Second point handle - Lenght: You can define a fixed lenght or use formulas for adaptive / calculated values
  • Second point handle - Angle: You can define a fixed angle or use formulas for adaptive / calculated values
  • Attributes: Specify the color, linetype and lineweight of the new node

Spline - Interactive (Shortcut Alt+S)

Create a curve that passes through multiple nodes
Click on each node in turn and press enter when done. You may now drag the handles around to make the curve more pleasing or use direction and angle formulas to get more precise curve. Hit Enter to finish selecting new points
  • Name: Name of the new node
  • Point: Selected point of pathlist
  • Path: List of selected points
  • First control point - Lenght: You can define a fixed lenght or use formulas for adaptive / calculated values
  • First control point - Angle: You can define a fixed angle or use formulas for adaptive / calculated values
  • Second control point - Lenght: You can define a fixed lenght or use formulas for adaptive / calculated values
  • Second control point - Angle: You can define a fixed angle or use formulas for adaptive / calculated values
  • Attributes: Specify the color, linetype and lineweight of the new node

Tool Curve tool which uses point as control handle

Available since version 0.5.0.

This tool uses 4 points to create a curve. So click on the 4 points in order of the direction you wish to go and a perfectly even curve will be created for you.

The only way to edit this, is to delete the curve and create a new one using other points. You may only change the line colour.

Note: As with all lines and curves, it will reshape itself if the measurements change.

Tool Curved path

Select all the points along the curve that you wish to create, press 'Enter' to end selecting and use the handles to tweak the curve to suit you. You need to select 3 or more points.

Note. This tool was redesigned in version 0.5.0. Since 0.5.0 you can control length and angle of 'handles' by formulas.

Tool Segment a curved path

Select the curve that you wish to segment, a formula box will pop up and you can select the exact segment you wish to place a point in and complete the formula.

Tool for creating curves

Available since version 0.5.0.

This is a great tool for creating full circle skirts but it has many other uses. Click on 7 or more points that you wish to use to create your curve and press 'Enter' when done. In the 1st image below, I have selected a number of points at random, just to show what it does. In the 2nd image, I have used it in the armhole (perhaps not the best place to use it). And in the 3rd image, I have used it to create the waist of a full circle skirt.

Tool Point intersection curves

Available since version 0.5.0.

Select the 1st curve and then the 2nd curve. A point will be placed at the place where the 2 curves intersect.

Tool Point intersect curve and axis

Select the curve. Click 1st axis point and then the next. A point will be placed where the curve and axis line intersect, with a line from the 1st axis point to the new point.

Note: I have mostly used the armhole curve to demonstrate these curves, so that one can identify with the use and view the differences created by using the different curve tools. For instance, the 'Tool for creating curves' wouldn't be the ideal tool to use at the armhole.

Fabrice has created a pattern illustrating the use of various points, lines and curves that you may download for further instruction:
