This tutorial was originally written by Roland Frank (†2017, r-frank), and it was rewritten and re-illustrated by vocx.
It is recommended to have completed the sketcher tutorial first.


This tutorial describes a method to create 3D text and use it with solid objects in the [[File:Workbench_Part.svg|24px]] [[Part_Workbench|Part Workbench]]. We will discuss how to
==Creating the basic shape==
* insert outlined text with the {{Button|[[Image:Draft_ShapeString.svg|16px]] [[Draft_ShapeString|Draft ShapeString]]}} tool,
*Start FreeCAD and create a new document
* extrude it to be a 3D solid with {{Button|[[File:Part_Extrude.svg|16px]] [[Part Extrude|Part Extrude]]}},
*Switch to part workbench
* position it in 3D space using [[placement|placement]], and {{Button|[[File:Draft_Move.svg|16px]] [[Draft Move|Draft Move]]}} (it uses a sketch as auxiliary geometry), and
*Insert a cube by clicking on [[Image:Part_Box.png|32px]]
* engrave the text by applying a boolean {{Button|[[File:Part_Cut.svg|16px]] [[Part Cut|Part Cut]]}}.

To use ShapeStrings inside the [[File:Workbench_PartDesign.svg|24px]] [[PartDesign_Workbench|PartDesign Workbench]], the process is essentially the same as with the Part Workbench, but the ShapeString is placed inside the [[PartDesign_Body|PartDesign Body]] to extrude it. Go to the end of this tutorial for more information.

A similar process as described above can be done with the [[PartDesign_Workbench|PartDesign Workbench]].

# Create the {{Button|[[File:Draft_ShapeString.svg|16px]] [[Draft_ShapeString|Draft ShapeString]]}} first.
# Create a {{Button|[[File:PartDesign_Body_Tree.svg|16px]] [[PartDesign_Body|PartDesign Body]]}}, make it active, and add a base solid by adding primitives, or using a Sketch and extruding it with {{Button|[[File:PartDesign_Pad.svg|16px]] [[PartDesign_Pad|PartDesign Pad]]}}.
# Move the {{incode|ShapeString}} object into the active body.
# Attach the {{incode|ShapeString}} object to one of the faces of the solid, or to a {{Button|[[File:PartDesign_Plane.svg|16px]] [[PartDesign Plane|PartDesign Plane]]}}, using {{Button|[[File:Part_EditAttachment.svg|16px]] [[Part_EditAttachment|Part EditAttachment]]}}.
# Now create a {{Button|[[File:PartDesign_Pad.svg|16px]] [[PartDesign_Pad|PartDesign Pad]]}} or a {{Button|[[File:PartDesign_Pocket.svg|16px]] [[PartDesign_Pocket|PartDesign Pocket]]}} from the {{incode|ShapeString}}, in order to produce an additive or a subtractive [[PartDesign_Feature|feature]] of the base body, respectively.

Introducere

În această lecţie vom discuta:

  • insert a text with the ShapeString tool
  • extrude it to be a solid
  • position it in 3D space using placement and Draft Move with sketches as helper elements
  • doing an engraving by applying a boolean cut

This tutorial was originally written by Roland Frank (†2017, r-frank), and it was rewritten and re-illustrated by vocx.

This tutorial describes a method to create 3D text and use it with solid objects in the Part Workbench. We will discuss how to

To use ShapeStrings inside the PartDesign Workbench, the process is essentially the same as with the Part Workbench, but the ShapeString is placed inside the PartDesign Body to extrude it. Go to the end of this tutorial for more information.

6.3. Press OK. This will create an Extrude object.
6.4. In the tree view, select Extrude, in the View tab change the value of Line Width to 2.0.

Text created as a ShapeString, and turned into a solid by extrusion.

Inserarea schiței pentru poziționare

  • Switch to sketcher workbench
  • Make sure object "chamfer" is selected in the tree view and press <Space> to toggle its visibility to visible
  • Choose sloped face created by chamfer operation
  • Click on to insert new sketch
  • Draw a line (may be horizontal or vertical, length is not of importance ...)
  • Constrain one of the endpoints to be +2,5 mm vertical distance and +2,5 mm horizontal distance away from the origin
  • Close the sketch

Now we will draw a simple sketch that will be used as auxiliary geometry to position the ShapeString extrusion.

7. In the tree view, select Extrude, and press Space in the keyboard to make it invisible.

8. Switch to the Sketcher Workbench.

9. In the tree view, select Chamfer, and press Space in the keyboard to make it visible.

9.1. Choose the sloped face created by the chamfer operation (Face3).
9.2. Click on NewSketch. In the Sketch attachment dialog, select FlatFace, and press OK.
9.3. The view should adjust automatically so that the camera is parallel to the selected face.
9.4. Draw a horizontal line in a general position on top of the face. The length is not important; we are just interested in its position.
9.5. Constrain the left endpoint to be 2.5 mm away from the local X axis and from the local Y axis, using ConstrainDistanceX and ConstrainDistanceY.
9.6. Since the sketch is just an auxiliary object, we don't need to have it fully constrained. You can do this if you wish by assigning a fixed distance, say, 20 mm, again with ConstrainDistanceX.
9.7. Close the sketch.

Line being created with the sketcher, with constraints.

Sketch line created on top of the solid face, to be used as reference guide for positioning the extruded text.

Posiționare text 3D în spațiul 3D

  • Make sure object "Extrude" is selected in the tree view and press <Space> to toggle visibility to visible
  • Make sure, object "Extrude" is selected in the tree view
  • Open Placement task Edit->Placement...
  • Apply incremental placement, axis of rotation Z=90°
  • Apply incremental placement, axis of rotation Y=45°
  • Switch to draft workbench
  • Switch to wireframe mode
  • Make sure, only "snap to endpoint" is activated Draft->Snapping->Snap to endpoint
  • Select "extrude"-object
  • Click on
  • In 3D view click on the most upper left corner point of "extrude"-object (1) and then click on the constrained point in the sketch (2)

10. In the tree view, select Extrude, and press Space in the keyboard to make it visible.

11. In the tree view, select Extrude, in the Data tab of the property editor, click on the Placement value so the ellipsis button ... appears on the right.

11.1. Tick the option Apply incremental changes.
11.2. Change the Rotation to Rotation axis with angle; Axis to Z, and Angle to 90 deg, then click on Apply. This will apply a rotation around the Z-axis, and will reset the Angle field to zero.
11.3. Change the Rotation to Rotation axis with angle; Axis to Y, and Angle to 45 deg, then click on Apply. This will apply a rotation around the Y-axis, and will reset the Angle field to zero.
11.4. Click on OK to close the dialog.

12. Switch again to the Draft Workbench.

12.1. Switch to "Wireframe" draw style with View → Draw style Wireframe, or press the Wireframe button in the view toolbar. This will allow you to see the objects behind other objects.
12.2. Make sure the Draft Snap "Snap to endpoint" method is active. This can be done from the menu Draft → Snapping → Toggle On/Off, and then File:Snap Endpoint.svg Endpoint, or by pressing the ToggleSnap and Snap endpoint buttons in the Snap toolbar.

13. In the tree view, select Extrude.

13.1. Click on Move.
13.2. In the 3D view click on the upper left corner point of the Extrude object (1), and then click on the leftmost point in the line drawn with the sketcher (2).
13.3. If Snap endpoint is active, as soon as you move the pointer close to a vertex, you should see that it attaches to it exactly.
Note: if you have problems snapping to vertices, make sure only the File:Snap Endpoint.svg Snap endpoint method is enabled. Having multiple snapping methods active at the same time may make it difficult to select the right feature.
13.4. The extruded text should now be inside the body of the Fillet object.

The extruded ShapeString should be moved to the position of the sketched line that lies on the face of the base body.

Extruded ShapeString positioned in the Fillet.

Creaţi un text gravat

  • Switch to part workbench
  • Switch to "As is"-view mode
  • Select the 3D text ("extrude") and then the base object ("chamfer") in the tree view
  • Apply a boolean cut by clicking on
  • Make sure object "Sketch" is selected in the tree view
  • Press <Space> to toggle visibilty
  • Click on to change to axometric view
  • Click on to zoom to fit all
  • Finished

14. Switch back to the Part Workbench.

14.1. Switch to "As is" draw style with View → Draw style As is, or press the As is button in the view toolbar. This will show all objects with the normal shading and color.
14.2. In the tree view, select Sketch, and press Space in the keyboard to make it invisible.

15. In the tree view select Chamfer first, and then Extrude.

15.1. Then press Cut. This will create a Cut object. This is the final object.
Note: the order in which you select the objects is important for the cut operation. The base object is selected first, and the subtracting object comes at the end.
15.2. In the tree view, select Cut, in the View tab change the value of Line Width to 2.0.

Final model of a filleted cube, with carved text created from a ShapeString, Extrude, and boolean Cut operations.

Engraving 3D text with the PartDesign Workbench

A similar process as described above can be done with the PartDesign Workbench.

  1. Create the Draft ShapeString first.
  2. Create a PartDesign Body, make it active, and add a base solid by adding primitives, or using a Sketch and extruding it with PartDesign Pad.
  3. Move the ShapeString object into the active body.
  4. Attach the ShapeString object to one of the faces of the solid, or to a PartDesign Plane, using Part EditAttachment.
  5. Now create a PartDesign Pad or a PartDesign Pocket from the ShapeString, in order to produce an additive or a subtractive feature of the base body, respectively.

See the forum thread, How to use ShapeStrings in PartDesign.
