简介

图像工作台用于管理不同类型的位图图像,用户可借此在FreeCAD中打开这些图像。

目前,该模块已支持打开BMP,JPG,PNG与XPM文件格式。

工具

  • Open: 在新的视口中打开图像。
  • Import to plane: 将图像导入至3D视图中的平面内。
  • Scaling: 对导入至平面内的图像进行缩放处理。

Features

  • Like a Sketch, an 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 workbench is tracing over the image, with the Draft or Sketcher tools, in order to generate a solid body based on the contours of 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 slightly behind the plane where you draw your 2D geometry, so you won't draw on the image itself.

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