<h2><span class="mw-headline" id=".D0.9E.D0.BF.D0.B8.D1.81.D0.B0.D0.BD.D0.B8.D0.B5">Описание</span></h2>
|
||
<p>Когда эскиз привязан к поверхности тела, инструмент Геометрия извне может использоваться, чтобы привязаться к краю или вершине этого тела. Он работает, вставляя в эскиз связанную конструктивную геометрию. Цвет по умолчанию для привязанных извне рёбер - пурпурный. Как при стандартной, не привязанной конструктивной геометрии (голубой), внешняя геометрия видна лишь когда эскиз в режиме редактирования и не используется напрямую в последующих результатах, от использования эскиза в других инструментах. Оба типа конструктивной геометрии используются как привязка для ограничений внутри эскиза.

<h2><span class="mw-headline" id="Use">Use</span></h2>
|
||
<ul><li> Create a new sketch, or open an existing sketch.</li>
|
||
<li> Click 'Sketcher External' button</li>
|
||
<li> Select an edge or a vertex that you want to link to in the sketch.</li>
|
||
<li> Press Esc, or select another tool to stop importing geometry into the sketch.</li></ul>
|
||
<h3><span class="mw-headline" id="Selection_rules">Selection rules</span></h3>
|
||
<p>Selection rules for what objects can be imported differ drastically between FC v0.16 and FC v0.17.
|
||
</p>
|
||
<h4><span class="mw-headline" id="v0.17">v0.17</span></h4>
|
||
<ul><li> Only edges and vertices from objects from same coordinate system are allowed.</li></ul>
|
||
<p>That is, the sketch and the object must be in same Body, or in same Part, or both outside of any Parts and Bodies.
|
||
</p><p>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.
|
||
</p>
|
||
<ul><li> No circular dependencies are allowed.</li></ul>
|
||
<p>That means, you can't link to Pocket made with this sketch. You can't link to any object that depends on the sketch.
|
||
</p><p>Unlike in v0.16, 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.
|
||
</p>
|
||
<h4><span class="mw-headline" id="v0.16_and_older">v0.16 and older</span></h4>
|
||
<ul><li> You can only link to edges/vertices of the shape the sketch is mapped to. </li></ul>
|
||
<p>For example. If Sketch was made on a face of Pad, you can only use edges/vertices of Pad. You can't use edges of Sketch that was used to make Pad. You can't use edges of Pad that are inherited onto a Pocket done with this sketch (you need to hide Pocket and unhide Pad to link new stuff in).
|
||
</p><p>The sketch MUST be mapped to a face in order to use this tool.
|
||
</p>
|
||
<h3><span class="mw-headline" id="Appearance_When_Successfully_Linked">Appearance When Successfully Linked</span></h3>
|
||
<p>A (default magenta) coloured line will be overlaid when an edge is successfully linked (the vertices will be red), and will be visible in your sketch only while your sketch is in edit mode.
|
||
</p>
|
||
<h3><span class="mw-headline" id="Similarity_to_Construction_Lines">Similarity to Construction Lines</span></h3>
|
||
<p>External geometry (default colour magenta) lines are similar (default colour blue) <a href="Sketcher_ConstructionMode.html" title="Sketcher ConstructionMode">Contruction lines</a> except in that the external geometry magenta lines are parametrically linked back to an element of the solid to which the sketch is mapped.
|
||
Construction geometry are lines that are internal to the sketch, are only visible when the sketch is in edit mode and will be used for constraint references only, and not directly for later solid operations, like Pad or Pocket.
|
||
</p><p><br />

</p>
|
||
<h3><span class="mw-headline" id="Use_Of_External_Geometry_in_a_PartDesign_Workbench_Work_Flow">Use Of External Geometry in a PartDesign Workbench Work Flow</span></h3>
|
||
<p>In the PartDesign workbench work flow, the External Geometry tool is used to assist in the positioning of an aspect of the solid you are constructing, relative to the previous stage in its construction. PartDesign workbench is intended to produce one single solid, therefore these sketches with external geometry are used to create a new feature of that one single solid.
|
||
</p><p>The external geometry can, for example, be used as a reference for a constraint being used to position a hole in an object at a specific location relative to an edge or vertex.
|
||
</p>
|
||
<h3><span class="mw-headline" id="Use_Of_External_Geometry_in_a_Part_Workbench_Work_Flow">Use Of External Geometry in a Part Workbench Work Flow</span></h3>
|
||
<p>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.
|
||
</p><p>In v0.16 and older, the sketch must be mapped to a face to use this tool. Since v0.17, this limitation was lifted.
|
||
</p>
|
||
<h2><span class="mw-headline" id="Example">Example</span></h2>
|
||
<p>This, below, is a sketch mapped to the top face of a solid created from a Pad of a previous sketch. The magenta lines are External Geometry linked to two edges of this pre-existing Pad.
|
||
</p><p>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.

|
||
</p><p>This is the same sketch in edit mode, with the Pad upon which it is mapped hidden.

|
||
</p><p>When the sketch edit mode is closed, External Geometry lines are not visible.
