Draft ShapeString tutorial/ro

Introducere
În această lecţie vom discuta:
 * insert a text with the [[Image:Draft_ShapeString.png|16px]] 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. We will discuss how to
 * insert outlined text with the tool,
 * extrude it to be a 3D solid with ,
 * position it in 3D space using placement, and (it uses a sketch as auxiliary geometry), and
 * engrave the text by applying a boolean.

To use ShapeStrings inside the PartDesign Workbench go to the end of this tutorial.

Setup
1. Open FreeCAD, create a new empty document with, and switch to the Part Workbench.
 * 1.1. Press the button, or press  in the numerical pad of your keyboard, to change the view to isometric to visualize the 3D solids better.
 * 1.2. Press the 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 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.

Crearea de texte 3D

 * Comutați pe Atelierul de Piese(Part workbench)
 * Make sure the object "Shapestring" is selected in the tree view
 * Use Part Extrude-Tool [[Image:Part_Extrude.png|32px]] with the parameters:
 * extrude Z=1 mm
 * make sure to tick "create solid"
 * use "OK" to finish part extrude operation
 * Make sure object "Extrude" is selected in the tree view and press  to toggle its visibility to be visible

6. Switch back to the Part Workbench.
 * 6.1. In the tree view, select, then press.
 * 6.2. In the task panel go to, choose ; in , set  to ; also tick the  option.
 * 6.3. Press . This will create an object.

Inserarea schiței pentru poziționare

 * Switch to sketcher workbench
 * Make sure object "chamfer" is selected in the tree view and press  to toggle its visibility to visible
 * Choose sloped face created by chamfer operation
 * Click on [[Image: Sketcher_NewSketch.png|32px]] 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, and press in the keyboard to make it invisible.

8. Switch to the Sketcher Workbench.

9. In the tree view, select, and press in the keyboard to make it visible.
 * 9.1. Choose the sloped face created by the chamfer operation.
 * 9.2. Click on . In the dialog, select, and press.
 * 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 away from the local X axis and from the local Y axis, using  and.
 * 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,, again with.
 * 9.7. Close the sketch.





Posiționare text 3D în spațiul 3D

 * Select "extrude"-object
 * Click on [[Image: Draft_Move.png|32px]]
 * 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, and press in the keyboard to make it visible.

11. In the tree view, select, in the tab of the property editor, click on the  value so the ellipsis button  appears on the right.
 * 11.1. Tick the option.
 * 11.2. Change the to ;  to, and  to , then click on . This will apply a rotation around the Z-axis, and will reset the  field to zero.
 * 11.3. Change the to ;  to, and  to , then click on . This will apply a rotation around the Y-axis, and will reset the  field to zero.
 * 11.4. Click on to close the dialog.

12. Switch again to the Draft Workbench.
 * 12.1. Switch to "Wireframe" draw style with, or press the 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, and then , or by pressing the and  buttons in the Snap toolbar.

13. In the tree view, select.
 * 13.1. Click on.
 * 13.2. In the 3D view click on the upper left corner point of the object (1), and then click on the leftmost point in the line drawn with the sketcher (2).
 * 13.3. If is active, as soon as you move the pointer close to a vertex, you should see that it attaches to it exactly.
 * if you have problems snapping to vertices, make sure only the 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 object.





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

 * Finished

14. Switch back to the Part Workbench.
 * 14.1. Switch to "As is" draw style with, or press the button in the view toolbar. This will show all objects with the normal shading and color.
 * 14.2. In the tree view, select, and press in the keyboard to make it invisible.

15. In the tree view select first, and then.
 * 15.1. Then press . This will create a object. This is the final object.
 * 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, in the tab change the value of  to.



Engraving 3D text with the PartDesign Workbench
A similar process as described above can be done with the PartDesign Workbench.


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