Curve Tool 1 - Curve Interactive Tool

[optimusprime93]

I want to draw a curve A6 and A5.

Question 1) I don’t understand how to draw this with the Curve Tool 1 - Curve Interactive Tool.

I could place a straight line with the Curve Tool 1 - Curve Interactive Tool.

and then adjust the square holders.

That’s It?

We created It with a curve tool why It is perceived as Straight line on the Piece Mode?

Question 2) Do I have to add nodes via Point On Curve or Point or Spline for which It will be perceived as curve in Piece Mode?

Point On Spline Point On Curve

Question 3) Also Grace told on the other topic Square Holders need to be perpendicular to the line. Do we adjust these manually and by eye?

Note : I understand what you have told on the other posts like adding node to a curve or theory behind It.

Yes… sort of. You can either drag the curve iteslf (which moves both handles) or drag a square handle to adjust the curve.

Sort of part:

1. Generally you want the angle of the control handle to be 90 degs to the seam it intersects with. This is just a basic sewing principle. In your case both control handle angles are not correct:

A6 should be 0 (or 360) degs - assuming A_A6 is 270. You can either

1. Open the curve tool properties and you can adjust the angle of control point 2:

2. Hold the shift key down while you grab the A6 control point and it will snap to 0 degs as you move it. Hint… always read the tooltips in the staus bar it will tell you how to use the tool:

A5 is a bit trickier as it has to be 90 to the shoulder seam: In that case you need to set a formula for the angle of Control point 1: Problem is you created the curve before you created the Line_A5_A8 so we can’t get the angle.

So Delete the curve and make a new one… which is now after point A8. Also draw it from A6 to A5 which will make things easier.

Click fx for the CP (control point) 2 angle:

Select Line Angles:

Clear the formula:

Find and select the shoulder Line_A5_A8 and to subtract 90 from the shoulder angle click:

The formula should now show:

Click OK.

tool dialog will show:

Click OK.

And now the control point is 90 to the shoulder seam:

That will work, but technically the curve will not resize properly without also using frmulas for the control point lengths.

There’s an easier solution. Use the Fixed - Curve tool.

First we need to create a fixed control point…which we can use the Point - Intersect XY tool using A5 and A6 as our points:

Now using the Fixed curve tool select Point A6, A10 (or what ever the pointname is), A5, and then A5 again:

It will now create a curve that is correct at both ends, and will automatically adjust to change in measurements - without having to deal with the control points. The new curve is in green:

Question 2) Do I have to add nodes via Point On Curve or Point or Spline for which It will be perceived as curve in Piece Mode?

No. You either have to select the curve when you create a new pattern piece OR use the Insert Nodes tool to add the curve node to the pattern piece main path

• as I have pointed out twice before now:

You currently have no curve in the main path of the pattenr piece:

Here I have added the (green) curve:

I could not use Point - Intersect XY Tool.

I click the first node. It shows a pink horizontal line. Then click the second node and the horizontal line diappears.

How do we use It here?

Click first on A1 and then on A to make this intersection:

Or click first on A and then on A1 to make this intersection:

If you are using the correct tool, then there shouldn’t be a problem:
