Translations:TechDraw LengthDimension/13/en

From FreeCAD Documentation
  1. Select the points and/or edges which define your measurement. The geometry may be selected in the 3D view (first two options) or in the drawing (all options):
    • Select two points.
    • Select a single straight edge.
    • Select two edges. If both edges are straight they must be parallel. This will produce a perpendicular dimension if an endpoint of one of the edges has a perpendicular projection on the other edge (the resultant point must lie on the actual edge). If multiple solutions are possible, the endpoint that is closest to its projected point is used. If there is no valid perpendicular projection, the dimension will be the distance between the nearest endpoints of the edges.
    • Select a point and an edge. This will produce a perpendicular dimension. In version 0.21 and below the dimension will only be perpendicular if the point has a perpendicular projection on the actual edge. Else the dimension will be the distance between the point and the nearest endpoint of the edge.
  2. If you have selected geometry in the 3D view: add the correct TechDraw View to the selection by selecting it in the Tree view.
  3. There are several ways to invoke the tool:
    • Press the Insert Length Dimension button.
    • Select the TechDraw → Dimensions → Insert Length Dimension option from the menu.
  4. A dimension is added to the View.
  5. The dimension may be dragged to the desired position.
  6. If needed, add tolerances as described on this page.
