A major use of this workbench is tracing over the image, with the [[Draft Workbench|Draft]] or [[Sketcher Workbench|Sketcher]] tools, in order to generate a solid body based on the contours of the image. |
|||
<div class="mw-translate-fuzzy"> |
|||
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. |

若要进行描边处理,最好是令图像距工作平面有个较小的负偏移量,例如-0.1 mm。这就意味着图像将稍稍偏于绘制2D几何图形平面的后侧,继而就不会把2D底图/草图绘制在图像上了。 |

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

可在导入图像时设置其偏移量,或者在后面的处理流程中通过修改其属性来实现这一点。 |

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。
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。
特性
- 与草图相似,我们可将导入的图像附于XY,XZ或YZ主平面之一,并为之调整正、负偏移值。
- 导入图像的比例关系为1像素:1毫米。
- 建议导入具有合理分辨率的图像。
Workflow
若要进行描边处理,最好是令图像距工作平面有个较小的负偏移量,例如-0.1 mm。这就意味着图像将稍稍偏于绘制2D几何图形平面的后侧,继而就不会把2D底图/草图绘制在图像上了。
可在导入图像时设置其偏移量,或者在后面的处理流程中通过修改其属性来实现这一点。
