<h2><span class="mw-headline" id="A_daily-life_problem">A daily-life problem</span></h2>
<p>Electric toothbrushes rarely come with a head stand, while in a family you will often see multiple heads used with one body. Many people facing a common problem lead us to a variety of solutions, as you can see on Thingiverse (200-800 projects are related to that). Here is the first answer and how to design it.
</p><p>This tutorial will take you through the steps needed to model the part shown in the image below using basic tools from the <a href="PartDesign_Workbench.html" title="PartDesign Workbench">Part Design Workbench</a> (many of the tools and capabilities are not covered).
</p>
<div class="center"><div class="floatnone"><a href="https://www.freecadweb.org/wiki/index.php?title=File:TBHS-model.png" class="image"><img alt="TBHS-model.png" src="TBHS-model.png" width="800" height="400" /></a></div></div>
<h2><span class="mw-headline" id="First_idea_:_a_plate">First idea&#160;: a plate</span></h2>
<ul><li>From the start-page, select <a href="https://www.freecadweb.org/wiki/index.php?title=File:Workbench_PartDesign.png" class="image"><img alt="Workbench PartDesign.png" src="Workbench_PartDesign.png" width="32" height="32" /></a> <i>Part Design</i>, or create a new document and select the <i>Part Design</i> workbench.</li></ul>

<p><br />
A dialog prompts you to choose the sketch orientation and provide an offset.
</p>
<ul><li>We will pick the XY Plane as shown in the image above (that orientation correspond to the common build plate of most 3D printers), then click OK.</li></ul>
<div class="center"><div class="floatnone"><a href="https://www.freecadweb.org/wiki/index.php?title=File:TBHS-2.JPG" class="image"><img alt="TBHS-2.JPG" src="800px-TBHS-2.JPG" width="800" height="434" srcset="/wiki/images/thumb/4/47/TBHS-2.JPG/1200px-TBHS-2.JPG 1.5x, /wiki/images/thumb/4/47/TBHS-2.JPG/1600px-TBHS-2.JPG 2x" /></a></div></div>
<p><br />
You now are facing the XY plane from above, and have access to the drawing tools.
</p>
<ul><li> Click on <a href="https://www.freecadweb.org/wiki/index.php?title=File:Sketcher_CreateRectangle.png" class="image"><img alt="Sketcher CreateRectangle.png" src="32px-Sketcher_CreateRectangle.png" width="32" height="32" srcset="/wiki/images/thumb/a/ad/Sketcher_CreateRectangle.png/48px-Sketcher_CreateRectangle.png 1.5x, /wiki/images/a/ad/Sketcher_CreateRectangle.png 2x" /></a> <a href="Sketcher_Rectangle.html" title="Sketcher Rectangle"><b>Rectangle</b></a>.</li>

<p><br />
You now have a floating rectangle of unspecified dimensions.
</p>
<ul><li> Click on a line of the rectangle, you now have access to the constraint tools at the right of the toolbar (depending of the size of your screen you may need to drag them to the left in order to see them all)</li>
<li> Click on <a href="https://www.freecadweb.org/wiki/index.php?title=File:Constraint_Length.png" class="image"><img alt="Constraint Length.png" src="32px-Constraint_Length.png" width="32" height="32" srcset="/wiki/images/thumb/a/a3/Constraint_Length.png/48px-Constraint_Length.png 1.5x, /wiki/images/a/a3/Constraint_Length.png 2x" /></a> <a href="Constraint_Length.html" title="Constraint Length"><b>Length</b></a></li>
<li> A dialog prompts you to set a dimension. Enter 80mm, click OK.</li>
<li> Repeat with the other side of the rectangle, also 80mm.</li></ul>
<div class="center"><div class="floatnone"><a href="https://www.freecadweb.org/wiki/index.php?title=File:TBHS-4.JPG" class="image"><img alt="TBHS-4.JPG" src="800px-TBHS-4.JPG" width="800" height="429" srcset="/wiki/images/thumb/a/a1/TBHS-4.JPG/1200px-TBHS-4.JPG 1.5x, /wiki/images/thumb/a/a1/TBHS-4.JPG/1600px-TBHS-4.JPG 2x" /></a></div></div>
<p><br />
You now have a floating square.
</p>
<ul><li> Click on the lower left point of the square.</li>
<li> Click on the origin of the XY plane (at the intersection of the two thick lines).</li>
<li> Click on <a href="https://www.freecadweb.org/wiki/index.php?title=File:Constraint_PointOnPoint.png" class="image"><img alt="Constraint PointOnPoint.png" src="32px-Constraint_PointOnPoint.png" width="32" height="32" srcset="/wiki/images/thumb/e/e3/Constraint_PointOnPoint.png/48px-Constraint_PointOnPoint.png 1.5x, /wiki/images/e/e3/Constraint_PointOnPoint.png 2x" /></a> <a href="Constraint_PointOnPoint.html" title="Constraint PointOnPoint"><b>Coincident</b></a>.</li></ul>

<p><br />
You now have a totally constrained sketch, as you are told by the solver on the left and the change of color.
It is a good practice to always have a totally constrained sketch.
</p><p>An under-constrained sketch can leave room for unwanted change, if you modify something later on.
On the opposite, an over-constrained sketch is also not good. In that case the solver warn you of redundant constraints and you should remove some of them.
</p>
<ul><li> To leave the sketch, click either on the "Close" button on the left, or the <a href="https://www.freecadweb.org/wiki/index.php?title=File:Sketcher_LeaveSketch.png" class="image"><img alt="Sketcher LeaveSketch.png" src="32px-Sketcher_LeaveSketch.png" width="32" height="32" srcset="/wiki/images/thumb/c/ce/Sketcher_LeaveSketch.png/48px-Sketcher_LeaveSketch.png 1.5x, /wiki/images/c/ce/Sketcher_LeaveSketch.png 2x" /></a> icon in the toolbar, or press <span style="background: #DDDDDD; border: 1px solid #888888; padding: 0px 5px 1px 5px;">ESC</span>.</li></ul>
<div class="center"><div class="floatnone"><a href="https://www.freecadweb.org/wiki/index.php?title=File:TBHS-6.JPG" class="image"><img alt="TBHS-6.JPG" src="800px-TBHS-6.JPG" width="800" height="434" srcset="/wiki/images/thumb/6/63/TBHS-6.JPG/1200px-TBHS-6.JPG 1.5x, /wiki/images/thumb/6/63/TBHS-6.JPG/1600px-TBHS-6.JPG 2x" /></a></div></div>
<p><br />
You now only see the square, and the contextual task menu on the left show you more options than before.
</p>
<h3><span class="mw-headline" id="Create_a_pad">Create a pad</span></h3>
