Point tools
Tools described in this section designed to allow create point at some conditions. Such conditions can be different, for example distance or angle, parents positions and etc.
Point - Lenght and Angle (Shortcut L, A)
Point - On Line (Shortcut O, L)
Point - Midpoint On Line (Shortcut Shift+O, Shift+L)
Point - On Perpendicular (Shortcut O, P)
Point - On Bisector (Shortcut O, B)
Point - Length to Line (Shortcut P, S)
Point - Intersect Arc and Line (Shortcut A, L)
Select the first and second points of the axis line (in this case, point A10 and A11 on the line indicating the shoulder tip height). Then select the point at the centre of the radius that you wish to measure out from (in this case, A9 - the edge of the neck). The box pops up and you may enter the length of the line from A9 to the new point (A12) that you require (shoulder width + the dart width). You may draw in a line from point A9 to A12 which will equal length that you entered.
If the distance between A9 and A12 is more than the pointer A11, it will do some very strange things and the Special point on shoulder will be the tool to use.
Tool Triangle tool
First choose your axis along which you'd like to place a point (A10 and A12). Then select the two points that you'd like to place a point where the two points form a right (90⁰) angle (A2 and A9) along the axis line.
Tool Point from X and Y of 2 other points
This will give you vertical cross hairs at the 1st point, horizontal cross hairs at the 2nd point and a point (with label) where the 2 intersect which you can change the name of if you wish.
Tool Perpendicular point along a line
You click on the point where you'd like the line to start and 2 other points between which, you'd like the line to intersect at a 90° angle. In the images below, a new point was created (A13) and the line goes from A10 to A13.
Tool Point intersect line and axis
First, you need to select 2 points along a line (that you'd like a line to end in line with) and then the point that you'd like to draw the line from. You will need to set the angle. I set the base line in the image below, to be from A2 to A14, the end line to be A12 and the angle at 265°. This placed a point (A14) between A2 and A14 and drew a line between A14 and A12. The degree of the angle extends from A12.
Tool True darts
As you know, when you have cut out your pattern and begin to sew, the edges of the darts are out of line if you only use the base line to create the dart. Allowances need to be made for the shift of the seam before cutting the fabric. This tool is meant to help you with that.
Select the line where you'd like to place a dart - A9 to A12. Then select the points of the dart - A17, A16 & A18. New points A19 & A20 are created and you may now draw your line from A9 to A19 to A16 to A20 and to A13 to get the perfectly fitted dart.
Tool Mid point between 2 points
Available since version 0.5.0.
This one works exactly like the 2nd tool above except that it will automatically take the current line length and divide it by 2 and place a point at that place (A21) - unless you change the formula.
