Rules for Automatic Hinge Boring and
Size Limits
Page 3 - Creating
the hinge sketches
Start by grabbing the Line 
tool and
drawing a short line parallel to the stile and about 2" long.
Make sure you are seeing the Vertical 
constraint glyph before
ending the line. If you don't have the Constraint placement
priority set to Horizontal and Vertical, you
should do so now by selecting the
Application Icon
, Options (at
the bottom), then on the Sketch tab, make the change in the 2D
sketch options at the upper left. Now, starting in the center of
the first line (wait for green dot as shown in the image below),
create another line tangential to the first. When you see the
Horizontal 
glyph, and the line is an
inch or so long, finish up the line. You should have something
that looks similar to the image on the right below...
Now you need to grab the Point 
tool from the Draw
tab, and add a point to all three line ends. When you get the
green dot, click. After the last point is placed, right click
anywhere and choose Done. Now get the Circle 
tool from the same
panel and draw three circles to get a sketch that looks similar
to the one below...
Now
window select the whole sketch you just created, and change the
lines to construction geometry. The points are the only geometry
that will be used to create features. The circles are only there
to show design intent. Now select the Project Geometry 
tool from
the Draw panel, open the origin folder in the browser, and select
the YZ Plane 
. Highlight the line just projected, and click the
Centerline 
tool located on the Format tab.
Now it is time to start adding dimensions to the geometry
using the parameters we created on
page one
.
Get the Dimension 
tool from the
Constrain Panel 
, and select the
uppermost circle. Click the little arrow pointing right on the
Edit Dimension 
dialog that appears, and choose List
Parameters from the list. Scroll through the list and find
Hinge_Cup_Diam and select it. The upper circle
should now display a diameter of fx:1.378. Now add dimensions to
the two lower circles, but this time use the
Hinge_Dowel_Diam as the parameter.
The new dimensions will display fx:.315. even though the parameter is stated in mm -this is because the standard units for this model are in inches.
Your
sketch should now look like the image to the left. Continue to
add dimensions by adding a dimension to the line that connects
the two smaller circles representing the dowel holes. Add the
Hinge_Dowel_Space parameter to that line. Add
the Hinge_Dowel_Offset to the other, tangential,
line that goes up to the large circle.
Now add a dimension from the centerpoint of the large circle to the line at the end of the stile (top edge that was projected at the beginning if the sketch) Use the Hinge_Offset_L parameter here.
The last dimension to add (for now) is the distance
between the large circle and the edge of the stile. To achieve
this, start by selecting the edge of the stile (line closest to
you) then move your curser over the point on the circle closest
to the line until you get the tangent glyph, then click and add
the Hinge_Setback parameter...
