In this case, you have to delete most of the corner points, then with the <code>SPACE</code> key transform 2-3 corner points into curve points. Otherwise, try smoothing.

In principle, someone is working on it and there should be a better version in a not so distant future.
If you want to modify this page, please discuss it with the person working on it (see the "history")

Intro

This tutorial explains how to change the shape of embroidery objects.


Union

Sometimes an automatic digitizing produces too many detailed objects. To embroider, with a weight 40 thread, two similar objects of 2-3mm side by side is not necessarily a good decision.

Here is a simple example of the "racing car" emoji (Noto font for Android 12). We first display the original in SVG, and the result of a semi-automatic digitization reduced to six colors (the original has 7)

The mirror contains two parts (red at the top and dark red at the bottom). The upper part is 3.16 x 1.82 millimeters and we can in our opinion unite it with the lower part. For this we use the operator "Weld" (fr. weld)

  • We select the two objects with CTRL-click
  • Toolboxes -> Edit Objects -> Weld
Weld (union) two embroidery objects

We propose the same operation for two other objects. For this type of embroidery, "less" is sometimes "more".

Changing the shape

We first take our racing car for a simple modification. In our opinion, the gray part under the car which touches the front wheel will not necessarily embroider well. So we propose to simplify the form. Also read the Reshape objects section of the official manual.

The Reshape button (either in the menu bar or in Toolboxes -> Edit Objects) puts us in the node editor which works on the same principle as a vector drawing editor (InkScape, Illustrator, Drawing in Word or PPT, etc.) since an embroidery object is a vector object. However, Hatch has simplified the type of operations that can be done in drawing software. Basically, to work a shape you just have to move corner points and curve points, a relatively easy method to learn. There are no "bezier" controls. It is rather a positive decision to help novices.

To modify the shape of an object, it is in your interest to enlarge it as much as possible:

  • Select subject
  • Press SHIFT-0 (or View -> Zoom -> Zoom to selected . As the zoom goes a bit too far, you can decrease it a bit by pressing -

The nodes editor displays (here) two types of nodes (ie points that define a shape).

  • The yellow squares are corner nodes (the lines that come out are straight)
  • The blue circles are curve nodes (the lines that come out are rounded)

The editor also displays the following:

  • The pairs of orange squares indicate the beginning and the end of a line of direction (here we see 3)
  • The entrance (place where the machine starts to stitch)
  • The exit (place where the machine finishes stitching)

It is suggested to simplify the shape and keep only one vertical direction line but a little leaning back.

Here are the basic operations:

  • Click on a node to select it. A selected node becomes dark.
  • You can select several nodes with CTRL-click or with a selection rectangle. This is convenient for deleting multiple.
  • The SPACE key transforms a curve node into a corner node, and vice versa.
  • The DEL key deletes a node.
  • Clicking on an edge adds a corner node.
  • Right-click on an edge adds a curved node.

The last two operations don't always seem to work. In addition, deleting a node may result in deleting a wider range. We don't understand why. Probably these nodes in question have a secret, hidden role :)

Edit Nodes

The Add Stitch Angles operator is used to add direction lines. You have to click on both sides of the shape and then middle-click to finish. Some operations are not permitted.

Here are the results of the changes. We also slightly pulled the red objects positioned higher.

Edit nodes: result

Auto Scan Issues

We found in an example discussed in an example emoji "hourglass" that Hatch can produce too many corner points (corner points) which is confusing stitch generation. We didn't really understand how to use the direction lines on the edges or Hatch is a bit limited at this level.

In this case, you have to delete most of the corner points, then with the SPACE key transform 2-3 corner points into curve points. Otherwise, try smoothing.
