## Working with section Point

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.

### Tool Point at distance and angle

This is a straight line. Click on the point that you’d like to start from and drag out a bit. Once you release, the following pops up and you can enter the dimensions you require:

1. Click to add a formula = The length of the line
2. Enter the length of the line manually
3. Click to add a formula = The degrees of the angle
4. Enter the degrees of the angle manually
5. The point that you originally clicked on above
6. You may change the point label here or it will give you the next generated point label
7. You may change the line color if you wish
8. Click Apply to see if your settings are correct and if so, click Ok to save and exit the box

### Tool Place a point at a distance along a line

The easiest is to click the label of the 1st point and then the label of the 2nd point in the direction that you want the distance to be measured from the 1st point. A box will pop up and you may enter the distance or enter a formula. This will only place a point of reference since the line type is automatically selected as ‘no color’ - you may choose another line type and color. You may change the label name.

### Tool Point along perpendicular

This is very handy when you wish to ‘square off’ from a particular point. In other words, create a line at a 90° angle from a point. Click on the point where you need to square off and drag around to another. A box will pop up where you may enter a formula or length of the line, change the label, use the arrows or enter the degrees for the ‘square off’, change the line type and change the color of the line. Once again, you can click apply to check that it is doing what you want before clicking ‘Ok’ to accept the instruction and close the box.

### Tool Point along bisector

Click on the 1st label, the 2nd label (where you would like the new line to intersect) and then on the 3rd label. A line will be drawn from the 2nd label outward between the 1st and 3rd labels. A box will pop up where you can enter either a formula or length of the new line and you may edit the other details if you wish.

### Tool Special point on shoulder

This one may be a little difficult to explain but I'll use my marks to help. You have a label at the shoulder point against the neck (A9) and a line below it to indicate the height of the shoulder tip (A10 to A11) to indicate where the chest joins the arm is situated. You'd like to draw a line from A9 to the shoulder tip plus you'd like to include the width of the dart. You click on A9, A10 and A11. The box will pop up and you may enter the formula for the shoulder width + the dart width. This will place a label point (A12) beyond A11 (in line with A10 to A11) where the line A9 to A12 will be the same length of the sum of the shoulder width + the dart width (in this case 1cm). You can now draw the line from A9 to A12 if you wish.

If the distance between A9 and A12 is less than the pointer A11, it will revert to point A11 and the Point at intersection of arc and line will be the tool to use.

### Tool Point at intersection of arc and line

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.
