<p><b>Attachment</b> is a utility to attach an object to another one. The attached object is linked to the other object, which means that if the latter's placement is changed afterwards, the attached object will update to its new position.

<ol><li> Select the object to be attached.</li>

<dl><dd> <b>Note</b>: when working in <a href="PartDesign_Workbench.html" title="PartDesign Workbench">PartDesign</a> and creating sketches, datum geometry or primitives, steps 1 and 2 are unnecessary: the Attachment dialogue is brought up automatically.</dd></dl></li>
|
|
<li> Under <b>Attachment</b> parameters, <i>Not attached</i> can be read. The first button below is labeled <span style="background: #DDDDDD; border: 1px solid #888888; padding: 0px 5px 1px 5px;">Selecting…</span> to indicate it is expecting a selection in the 3D view.</li>
|
|
<li> Select a topology element on the object to attach to: vertex, edge or face/plane. Datum geometry from <a href="Std_Part.html" title="Std Part">Part containers</a> are also selectable.</li>
|
|
<li> The first button's label now adopts the type of topology selected. In the white field to its right, the referenced object and its element is added. For example, if a face on a primitive cube is selected, the field will show Box:Face6.</li>
|
|
<li> Select an <a href="#Attachment_mode">Attachment mode</a> in the list. The available modes are filtered by the selected references. <i>Attached with mode <mode description></i> will be displayed under the <b>Attachment</b> header.
|
|
<dl><dd> For live information on the attachment modes, hover the mouse on top of one of the modes in the list for a tooltip to appear.</dd></dl></li>

<li> Optionally, add up to 3 more references by pressing the <span style="background: #DDDDDD; border: 1px solid #888888; padding: 0px 5px 1px 5px;">Reference2</span>, <span style="background: #DDDDDD; border: 1px solid #888888; padding: 0px 5px 1px 5px;">Reference3</span>, and <span style="background: #DDDDDD; border: 1px solid #888888; padding: 0px 5px 1px 5px;">Reference4</span> buttons and repeating step 4.</li>

<h3><span class="mw-headline" id="Attachment_Offset">Attachment Offset</span></h3>
|
|
<p>Attachment Offset is used to apply a linear or rotary offset from the referenced object. It becomes active when an attachment mode other than <i>Deactivated</i> has been selected .
|
|
</p>
|
|
<ul><li> <b>X</b>: sets an offset distance in the X axis of the reference object .</li></ul>
|
|
<ul><li> <b>Y</b>: sets an offset distance in the Y axis of the reference object .</li></ul>
|
|
<ul><li> <b>Z</b>: sets an offset distance in the Z axis of the reference object .</li></ul>
|
|
<ul><li> <b>Yaw</b>: rotates the attached object along the reference object's Z axis .</li></ul>
|
|
<ul><li> <b>Pitch</b>: rotates the attached object along the reference object's Y axis .</li></ul>
|
|
<ul><li> <b>Roll</b>: rotates the attached object along the reference object's X axis .</li></ul>
|
|
<ul><li> <b>Flip sides</b>: if checked, the attached object is reversed from its XY plane .</li></ul>
