|
|
<p>The Geometry Editor is a drawing CAD that allows you to edit
|
|
FlatCAM Geometry Objects or create new ones from scratch. This
|
|
provides the ultimate flexibility by letting you specify precisely
|
|
and arbitrarily what you want your CNC router to do.</p>

<h2>Creating New Geometry Objects<a class="headerlink" href="#creating-new-geometry-objects" title="Permalink to this headline">¶</a></h2>
|
|
<p>To create a blank Geometry Object, simply click on the menu item
|
|
<strong>Edit→New Geometry Object</strong> or click the <strong>New Blank Geometry</strong> button on
|
|
the toolbar. A Geometry object with the name “New Geometry” will
|
|
be added to your project list.</p>

<h2>Editing Existing Geometry Objects<a class="headerlink" href="#editing-existing-geometry-objects" title="Permalink to this headline">¶</a></h2>
|
|
<p>To edit a Geometry Object, select it from the project list and
|
|
click on the menu item <strong>Edit→Edit Geometry</strong> or on the <strong>Edit Geometry</strong>
|
|
toolbar button.</p>
|
|
<p>This will make a copy of the selected object in the editor and
|
|
the editor toolbar buttons will become active.</p>
|
|
<p>Changes made to the geometry in the editor will not affect the
|
|
Geometry Object until the <strong>Edit->Update Geometry</strong> button or
|
|
<strong>Update Geometry</strong> toolbar button is clicked.
|
|
This replaces the geometry in the currently selected Geometry
|
|
Object (which can be different from which the editor copied its
|
|
contents originally) with the geometry in the editor.</p>

<p>When the <strong>Selection Tool</strong> is active in the toolbar (Hit <tt class="docutils literal"><span class="pre">Esc</span></tt>), clicking on the
|
|
plot will select the nearest shape. If one shape is inside the other,
|
|
you might need to move the outer one to get to the inner one. This
|
|
behavior might be improved in the future.</p>
|
|
<p>Holding the <tt class="docutils literal"><span class="pre">Control</span></tt> key while clicking will add the nearest shape
|
|
to the set of selected objects.</p>

on the status bar.</p>
|
|
<p>Shapes that do not require a fixed number of clicks to complete, like
|
|
polygons and paths, are complete by hitting the <tt class="docutils literal"><span class="pre">Space</span></tt> key.</p>
|
|
<p>Certain shape tools can have different options or modes. By hitting
|
|
<cite>o</cite> and/or <cite>p</cite> the tool will cycle through its options and/or modes.</p>
