* Create a new sketch, or open an existing sketch.
* Press the {{Button|[[File:Sketcher_External.svg|16px]] [[Sketcher_External|Create an external geometry]]}} button.
* Select an edge or a vertex that you want to link to in the sketch.
* Press {{KEY|Esc}}, or select another tool to stop importing geometry into the sketch.

=== Selection rules ===
* Only edges and vertices from objects from same coordinate system are allowed.

That is, the sketch and the object must be in same Body (when in Part Design workbench), or in same Part (when in Part workbench), or both outside of any Parts and Bodies.

For example, If the open sketch is in Body, you can use another sketch from Body as external geometry, but you can't use a sketch from Body001, or an edge from a Part Cube in the root of the project. Use Shapebinder feature to bring in a copy of the object into the coordinate system of open sketch. Then you will be able to use edges/vertices of Shapebinder object.

* No circular dependencies are allowed.

That means, you can't link to Pocket made with this sketch. You can't link to any object that depends on the sketch.

Sketch doesn't have to be on any face in order to use this tool. Links directly between sketches are possible, and encouraged, as they are more reliable.

One can use this to dimension one sketch off of another using the following order of operations:

You can use any Part geometry that is in coordinate system of the sketch. It is advised to link to the earliest feature possible, as it forms a more stable link.

==Příklad==

Linky v barvě magenta jsou Přetažené konstrukce vybrané ve dvou objektech stejného vysunutého produktu z předchozího náčrtu.
V takovém případě jsou použity k vytvoření vazeb dotyku s obvodem.
Linka na menším obdélníku není využita.

In this case they are used as a reference for tangency constraints with the circumferences of one circle. They are also used as the reference for a horizontal and a vertical constraint to locate the centre of the second circle relative to the end and top of the Pad.

Popis

Tento nástroj přetáhne linky konstrukce do aktuálního náčrtu. Když jsou linky přetaženy, zobrazí se v náčrtu v barvě magenta a můžete na ně navázat linky v náčrtu a rozměry.

The two magenta lines are external geometry linked to edges of a pre-existing Pad. They are used to constrain the circles.

Použití

  • Začněte náčrt na ploše tělesa (klikněte na plochu tělesa, potom klikněte na tlačítko pro vytvoření náčrtu)
  • Klikněte na tlačítko 'Povrchový náčrt'
  • Vyberte linky tělesa, které chcete přetáhnout do náčrtu (pamatujte na to, že to musejí být linky ve stejné rovině jako je náčrt)

See also: Drawing aids.

  1. There are several ways to invoke the tool:
    • Press the Create external geometry button.
    • Select the Sketcher → Sketcher geometries → Create external geometry option from the menu.
    • Right-click in the 3D view and select the Create external geometry option from the context menu.
    • Use the keyboard shortcut: G then X.
  2. The cursor changes to a cross with the tool icon.
  3. Select an external edge or a vertex. See Notes.
  4. External geometry is created.
  5. This tool always runs in continue mode: optionally keep selecting external edges and/or a vertices.
  6. To finish, right-click or press Esc, or start another geometry or constraint creation tool.

Notes

  • Only edges and vertices from objects within the same coordinate system can be selected. The sketch and the object must be in same Body, or the same Part, or both in the global coordinate system. Use a Binder to bring a copy of the object into the current coordinate system if required.
  • Circular dependencies are not allowed. You cannot link to an object that depends on the sketch itself.
  • Links to elements from other sketches are possible, and encouraged, as they are more reliable than links to generated (solid) geometry. The latter can suffer from the Topological Naming Problem. See Advice for stable models.
