==Introduction== |
==Introduction== |
||
In this tutorial we will discuss how to |
|||
* insert a text with the [[Image:Draft_ShapeString.png|16px]] [[Draft_ShapeString|ShapeString]] tool |
|||
* extrude it to be a solid |
|||
* position it in 3D space using [[placement|placement]] and [[Draft Move|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. |
|||
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]]}}. |
|||
*Make sure the cube is selected in the tree view |
|||
*Change width to be 31 mm by using the data-tab in the property view |
|||
*Click on [[Image:View-axometric.png|32px]] to change to axometric view |
|||
*Click on [[Image:View-zoom-all.png|32px]] to zoom to fit all |
|||
*Select upper edge on the front face of the cube in 3D view |
|||
*Apply a chamfer (to Edge6) of 5 mm by clicking on [[Image:Part_Chamfer.png|32px]] |
|||
*Make sure object "chamfer" is selected in the tree view and press <Space> to toggle visibility |
|||
[[Image:TutorialDraftShapeString_BasicShape.jpg|300px]] |
|||
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. |
|||
==Inserting text with the Draft ShapeString tool== |
|||
*Switch to Draft workbench |
|||
*make sure nothing is selected in the tree view |
|||
*Toggle working plane to XY (Top) by clicking on {{KEY| [[Image:Draft_SelectPlane.png|32px]] Auto}} and choosing {{KEY| XY}} |
|||
*Insert text "FreeCAD" by |
|||
**Click on [[Image:Draft_ShapeString.png|32px]] |

|||
{{Caption|Text created as a ShapeString, and turned into a solid by extrusion.}} |
|||
==Insert auxiliary sketch for positioning== |
|||
Now we will draw a simple sketch that will be used as auxiliary geometry to position the ShapeString extrusion. |
|||
7. In the [[Tree_view|tree view]], select {{incode|Extrude}}, and press {{KEY|Space}} in the keyboard to make it invisible. |
|||
8. Switch to the [[Sketcher_Workbench|Sketcher Workbench]]. |
|||
9. In the [[Tree_view|tree view]], select {{incode|Chamfer}}, and press {{KEY|Space}} in the keyboard to make it visible. |
|||
:9.1. Choose the sloped face created by the chamfer operation ({{incode|Face3}}). |
|||
:9.2. Click on {{Button|[[File:Sketcher_NewSketch.svg|16px]] [[Sketcher_NewSketch|NewSketch]]}}. In the {{MenuCommand|Sketch attachment}} dialog, select {{incode|FlatFace}}, and press {{Button|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 {{incode|2.5 mm}} away from the local X axis and from the local Y axis, using {{Button|[[File:Sketcher_ConstrainDistanceX.svg|16px]] [[Sketcher_ConstrainDistanceX|ConstrainDistanceX]]}} and {{Button|[[File:Sketcher_ConstrainDistanceY.svg|16px]] [[Sketcher_ConstrainDistanceY|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, {{incode|20 mm}}, again with {{Button|[[File:Sketcher_ConstrainDistanceX.svg|16px]] [[Sketcher_ConstrainDistanceX|ConstrainDistanceX]]}}. |
|||
:9.7. Close the sketch. |

==Positioning the solid text in 3D space== |
|||
10. In the [[Tree_view|tree view]], select {{incode|Extrude}}, and press {{KEY|Space}} in the keyboard to make it visible. |
|||
11. With {{incode|Extrude}} still selected, in the {{MenuCommand|Data}} tab of the [[property editor|property editor]], click on the {{MenuCommand|Placement}} value so the ellipsis button {{Button|...}} appears on the right and click on that button. |
|||
:11.1. Tick the option {{MenuCommand|Apply incremental changes}}. |
|||
:11.2. Change the {{MenuCommand|Rotation}} to {{incode|Rotation axis with angle}}; {{MenuCommand|Axis}} to {{incode|Z}} (by setting the {{incode|X}}, {{incode|Y}} and {{incode|Z}} values of the axis inputboxes to {{incode|0}}, {{incode|0}} and {{incode|1}} respectively, {{incode|Z}} is the third inputbox), and {{MenuCommand|Angle}} to {{incode|90 deg}}, then click on {{Button|Apply}}. This will apply a rotation around the Z-axis, and will reset the {{MenuCommand|Angle}} field to zero. |
|||
:11.3. Change the {{MenuCommand|Rotation}} to {{incode|Rotation axis with angle}}; {{MenuCommand|Axis}} to {{incode|Y}} (by setting the {{incode|X}}, {{incode|Y}} and {{incode|Z}} values of the axis inputboxes to {{incode|0}}, {{incode|1}} and {{incode|0}} respectively), and {{MenuCommand|Angle}} to {{incode|45 deg}}, then click on {{Button|Apply}}. This will apply a rotation around the Y-axis, and will reset the {{MenuCommand|Angle}} field to zero. |
|||
:11.4. Click on {{Button|OK}} to close the dialog. |
|||
12. Switch again to the [[Draft_Workbench|Draft Workbench]]. |

:12.1. Switch to "Wireframe" draw style with {{MenuCommand|View → [[Std_DrawStyle|Draw style]] → [[File:DrawStyleWireFrame.svg|16px]] Wireframe}}, or press the {{Button|[[File:DrawStyleWireFrame.svg|16px]] [[Std_DrawStyle|Wireframe]]}} button in the view toolbar. This will allow you to see the objects behind other objects. |
|||
:12.2. Make sure the [[Draft_Snap|Draft Snap]] "Snap to endpoint" method is active. This can be done from the menu {{MenuCommand|Draft → Snapping → [[File:Draft_Snap_Lock.svg|16px]] [[Draft_Snap_Lock|Toggle On/Off]]}}, and then {{MenuCommand| → [[File:Draft_Snap_Endpoint.svg|16px]] [[Draft_Snap_Endpoint|Endpoint]]}}, or by pressing the {{Button|[[File:Draft_Snap_Lock.svg|16px]] [[Draft_Snap_Lock|ToggleSnap]]}} and {{Button|[[File:Draft_Snap_Endpoint.svg|16px]] [[Draft_Snap_Endpoint|Snap endpoint]]}} buttons in the Snap toolbar. |
|||
13. In the [[Tree_view|tree view]], select {{incode|Extrude}}. |
|||
:13.1. Click on {{Button|[[File:Draft_Move.svg|16px]] [[Draft_Move|Move]]}}. |
|||
:13.2. In the [[3D_view|3D view]] click on the upper left corner point of the {{incode|Extrude}} object (1), and then click on the leftmost point in the line drawn with the sketcher (2). |
|||
:13.3. If {{Button|[[File:Draft_Snap_Endpoint.svg|16px]] [[Draft_Snap_Endpoint|Snap endpoint]]}} is active, as soon as you move the pointer close to a vertex, you should see that it attaches to it exactly. |
|||
:{{Emphasis|Note:}} if you have problems snapping to vertices, make sure only the {{Button|[[File:Draft_Snap_Endpoint.svg|16px]] [[Draft_Snap_Endpoint|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 {{incode|Chamfer}} object. |
|||

Introduction
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
- insert outlined text with the Draft ShapeString tool,
- extrude it to be a 3D solid with Part Extrude,
- position it in 3D space using placement, and Draft Move (it uses a sketch as auxiliary geometry), and
- engrave the text by applying a boolean Part Cut.
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.
Final model of the engraved text.
The Sketcher Workbench is used briefly to draw an auxiliary line. More information about the tools of this workbench can be found in
Setup
1. Open FreeCAD, create a new empty document with File → New, and switch to the Part Workbench.
- 1.1. Press the View isometric button, or press 0 in the numerical pad of your keyboard, to change the view to isometric to visualize the 3D solids better.
- 1.2. Press the View fit all button whenever you add objects in order to pan and zoom the 3D view so that all elements are seen in the view.
- 1.3. Hold Ctrl while you click to select multiple items. If you selected something wrong or want to de-select everything, just click on empty space in the 3D view.
Create the basic shape
2. Insert a primitive cube by clicking on Box.
- 2.1. Select
Cube
in the tree view. - 2.2. Change the dimensions in the Data tab of the property editor.
- 2.3. Change Width to
31 mm
.
3. Create a chamfer.
- 3.1. Select the upper edge (
Edge6
) on the front face of theCube
in the 3D view. - 3.2. Press Chamfer.
- 3.3. In the Chamfer edges task panel go to Selection, choose Select edges. As Chamfer type choose

- 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.

and0
respectively), and Angle to45 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 → 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 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
Chamfer
object.
The extruded ShapeString should be moved to the position of the sketched line that lies on the face of the base body.

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 to2.0
.
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.
- Create the Draft ShapeString first.
- 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.
- Move the
ShapeString
object into the active body. - Attach the
ShapeString
object to one of the faces of the solid, or to a PartDesign Plane, using Part EditAttachment. - 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.
