A major use of this tool is tracing over the image, with the [[Draft Workbench|Draft]] or [[Sketcher Workbench]]es, in order to extrude the shape, and generate a new part based on the image.
Tracing with sketcher elements over an image works best if the image has a small (negative) offset to the sketch plane.


Tracing over an image works best if the image has a small negative offset, for example, -0.1 mm, from the working plane. This means that the image will be behind the plane were you draw the contours of the image.
You can set an offset of -0,1 mm at import or later by editing the placement of the image.

The offset of the image can be set during import, or changed later in its properties.

Introduction

The Image Workbench manages different types of bitmap images, and allows you to open them in FreeCAD.

Currently, the module supports opening BMP, JPG, PNG, and XPM file formats.

Tools

Image Import: import an image on a plane in the 3D view.

Features

  • Like a Sketch, the imported image can be attached to one of the main planes XY, XZ, or YZ, and given a positive or negative offset.
  • The image is imported with relation of 1 pixel to 1 millimeter.
  • The recommendation is to have the imported image at a reasonable resolution.

Workflow

A major use of this tool is tracing over the image, with the Draft or Sketcher Workbenches, in order to extrude the shape, and generate a new part based on the image.

Tracing over an image works best if the image has a small negative offset, for example, -0.1 mm, from the working plane. This means that the image will be behind the plane were you draw the contours of the image.

The offset of the image can be set during import, or changed later in its properties.
