Clone by Offset Use Cases

This section describes several clone by offset use cases, giving more information about how the feature works with internal lines. The content is divided into the following parts:

Horizontal Lines

The following image shows an example of a pattern piece with a 3 cm horizontal internal line.

Horizontal line

In the following examples, the above line is referred to as the original line.

Measure from Border

Assume you clone the line with these settings:

Clone by offset settings

The software creates an internal line which is at the same height and starts 2 cm (along the x-axis) from the border of the original line as shown in the following image. The border, in this case, is the right end of the original line.

Cloned horizontal line

If you wanted the cloned line to appear to the left of the original line, you would enter -2 cm for X instead of 2 cm.

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to and 2 cm (along the y-axis) from the border of the original line as shown in the following image. The border, in this case, is the bottom edge of the original line.

Cloned horizontal line

If you wanted the cloned line to appear to the top of the original line, you would enter -2 cm for Y instead of 2 cm. In the software, a positive value on the y-axis is down the screen and a negative value is up the screen.

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to the original line and starts 2 cm down the y-axis and 2 cm along the x-axis from the border of the original line as shown in the following image. The border, in this case, is the right edge of the original line.

Cloned horizontal line

Measure from Center

Now assume you clone the original line using the Center setting like this:

Clone by offset settings

The software creates an internal line which starts 2 cm along the x-axis from the left side of the original line - not the center - as shown in the following image.

Cloned horizontal line

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to and 2 cm along the y-axis from the original line as shown in the following image.

Cloned horizontal line

The output in this case is the same as if the settings were Border and Y = 2 cm.

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to the original line, starting 2 cm along the x-axis from the left side of the original line - not the center - and 2 cm down the y-axis, as shown in the following image.

Cloned horizontal line

Vertical Lines

The following image shows an example of a pattern piece with a 3 cm vertical internal line.

Vertical line

In the following examples, the above line is referred to as the original line.

Measure from Border

Assume you clone the line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to the original line and 2 cm along the x-axis from the border of the original line as shown in the following image. The border, in this case, is the original line.

Cloned vertical line

If you wanted the cloned line to appear to the left of the original line, you would enter -2 cm for X instead of 2 cm.

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which starts 2 cm down the y-axis from the border of the original line as shown in the following image. The border, in this case, is the bottom of the original line.

Cloned vertical line

If you wanted the cloned line to appear to the top of the original line, you would enter -2 cm for Y instead of 2 cm. In the software, a positive value on the y-axis is down the screen and a negative value is up the screen.

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to the original line, 2 cm along the x-axis and 2 cm down the y-axis from the border of the original line as shown in the following image. The border, in this case, is the bottom edge of the original line.

Cloned vertical line

Measure from Center

Now assume you clone the original line using the Center setting like this:

Clone by offset settings

The software creates an internal line which is parallel to the original line and 2 cm along the x-axis from the original line as shown in the following image.

Cloned vertical line

  • If you wanted the cloned line to appear to the left of the original line, you would enter -2 cm for X instead of 2 cm.

  • The output in this case is the same as if the settings were Border and X = 2 cm.

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which starts 2 cm down the y-axis from the top of the original line - not the center - as shown in the following image.

Cloned vertical line

If you wanted the cloned line to appear towards the top left of the original line, you would enter -2 cm for Y instead of 2 cm. In the software, a positive value on the y-axis is down the screen and a negative value is up the screen.

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to the original line, starting 2 cm along the x-axis and 2 cm down the y-axis from the bottom of the original line as shown in the following image.

Cloned vertical line

If you wanted the cloned line to appear to the top right of the original line, you would enter -2 cm for Y instead of 2 cm. In the software, a positive value on the y-axis is down the screen and a negative value is up the screen.

Diagonal Lines

If you apply Clone by Offset to a diagonal line, note how the distance from the original line is calculated.

The following image shows an example of a pattern piece with a 3 cm internal line.

Diagonal line

In the following examples, the above line is referred to as the original line.

Measure from Border

Assume you clone the line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to the original line and starts 2 cm along the x-axis from the border of the original line as shown in the following image. The border, in this case, is the right end of the original line.

Cloned diagonal line

If you wanted the cloned line to appear to the left of the original line, you would enter -2 cm for X instead of 2 cm.

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to the original line, starting 2 cm down the y-axis from the border of the original line as shown in the following image. The border, in this case, is the bottom edge of the original line.

Cloned diagonal line

If you wanted the cloned line to appear to the top of the original line, you would enter -2 cm for Y instead of 2 cm. In the software, a positive value on the y-axis is down the screen and a negative value is up the screen.

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to the original line, starting 2 cm along the x-axis and 2 cm down the y-axis from the border of the original line as shown in the following image. The border, in this case, is the right end of the original line.

Cloned diagonal line

Measure from Center

Now assume you clone the original line using the Center setting like this:

The software creates an internal line which is parallel to the original line, 2 cm down the y-axis from the original line as shown in the following image.

Cloned diagonal line

Assume you clone the original line with these settings:

Clone by offset settings

The software creates an internal line which is parallel to the original line, starting at a point which is 2 cm down the y-axis from the left side of the original line - not the center - and from there 2 cm along the x-axis, as shown in the following image.

Cloned diagonal line

Diagonal Line Workaround

The Clone by Offset feature does not clone diagonal lines using a distance measured perpendicularly (at right angles) to the original line.

For example, here is the original diagonal line 3 cm long.

Diagonal line

Assume you clone the line with these settings:

Clone by offset settings

The following image shows the result.

Cloned diagonal line

But assume this is what you wanted.

Diagonal line and clone

How do you create a clone of an internal diagonal line which is at a distance measured at a right angle from the original line?

You can use the following technique to achieve this:

  1. Take a side note of the length of the original line you want to clone.

  2. Right-click the original line you want to clone. Note: From now on, this is referred to as the first line.

  3. Click Create Guideline. A guideline is created. Note: From now on, this is referred to as the first guideline.

  4. Select the first guideline. Note: Ensure you select the first guideline, not the first line.

  5. Go to the Context view, in the Actions section and click Clone by Offset.

  6. In Spacing, type in the distance from the first guideline where you want the cloned line to be, then click Apply.

    • A positive number puts the cloned guideline to the right of the original line.

    • A negative number puts the cloned guideline to the left of the original line.

    A cloned guideline is created. Note: From now on, this is referred to as the second guideline.

  7. Multi-Select the second guideline and the pattern piece. (Press Shift when clicking to select both items.)

  8. Go to the Context view, in the Actions section and click Trace as Internal Line. A new internal line is created which is the correct distance away from the original line. It is , however, the wrong length. Note: From now on, this is referred to as the second line.

  9. Drag the second guideline away so you can see the second line, then click to select the second line.

  10. Go to the Context view, in the Transformation section and at Length type in the correct value. Now the second line is the correct length but it is not correctly aligned.

  11. Select the second line.

  12. Go to the Context view, in the Line Properties section and ensure Glue is cleared.

  13. Drag the second guideline so that it runs directly through the second line.

  14. Select the first guideline.

  15. Go to the Context view and in the Transformation section, click Rotate 90 degrees. The first guideline is now perpendicular to the first line.

  16. Drag the first guideline so that it intersects one end of the first line.

  17. Select the second line and drag it along the second guideline until it is in the correct position.

The following image shows an example of using this workaround.
