Drafting the profile
- Select the DWire (multiple-point DraftWire) tool.
- Check the "Relative" and "Filled" boxes.
- Rather than drawing the shape in the 3D view, we'll enter coordinates in the Global X, Global Y and Global Z input fields. The process is the following:
- Click in the Global X input field;
- Enter a value as listed in the bullet list below and press TAB to go to the Global Y input field;
- Enter the Global Y value and press TAB to go to the Global Z input field;
- In the Global Z field, leave the zero value and press ENTER to validate the coordinates for the point;
- Repeat for the next 5 points.
- Coordinates (X, Y, Z)
- 1st point: 0, 0, 0
- 2nd point: 50, 0, 0
- 3rd point: 0,10, 0
- 4th point: -40, 0, 0 Note: in FreeCAD 0.16, there is a bug that removes the previous point when entering the minus sign in the input field. A workaround is to enter a positive value, then place the cursor before the number and add the minus sign. (This bug is resolved in v0.17)
- 5th point: 0, 40, 0
- 6th point: -10, 0, 0
