iLogic Tutorial – 06 – The Dovetail Profile Sketch Creation

Now create a Vertical Line from the projected point below the cutter profile upwards a bit. Add the Tail_Spacing parameter to it as shown…

…then use the Coincident Constraint tool to connect the cutter profile with the tail spacing line as shown below…

…you should now have a fully constrained sketch that looks like the one shown below.

We will now add the geometry that will give us the profile at the depth of cut regardless of the cutter angle. Start by drawing two lines, one up, and one down from the end of the cut depth line to just past the angled line of the cutter as shown below…

…make sure you are seeing the horizontal constraint glyphs before accepting the lines.

iLogic Tutorial – 02 – Creating the Drawer Elevation Sketch

Start a sketch on the XZ Origin plane, and name it Drawer Elevation. Grab the Project Geometry  tool from the Draw panel, and project the end of the rigging line that represents the width extents on the right hand side of the model (X+)….

 

Project Point

The Dovetail Drawer Side

 

 

 

 

 

…now starting on this new point, draw a two point rectangle up and to the left, then a smaller rectangle overlapping it to get something like the image to the right.

 Now grab the Trim tool from the Modify panel, and trim off all of the portion of the smaller rectangle that lies outside of the larger one. Right click to bring up the context menu, choose Split from the list, then split the left line at both the top and bottom of the little rectangle.

 

 

 

 

Now add the parameters. Start with the two parameters for the dado (small rectangle), then move on to the drawer bottom reveal (height of the dado from the bottom), then go onto the larger rectangle which is the drawer side.

 

iLogic Tutorial for the iDrawer Page Two Image 05 - The iLogic Parameters

The last thing to do on this sketch is to establish a reference parameter. First I changed the dimension display back to Value from Expression (it’s on the right click menu whenever a sketch is active) so that the sketch isn’t so cluttered, then place a dimension between the center point and the bottom of the dado as shown below…

…now go to the parameter editor and under the reference parameters there will be a new parameter that should be named d8 with an Equation of 8.750 in. Change the name as shown below (note the underscores between words). This completes the side profile, next, we will sketch the front profile…

The good news is that it didn’t take excessively long to demote the parts created in the ‘Make Components’ procedure to their respective sub assemblies…

.

…the bad news is that it took time (money) at all, and that a couple errors were introduced in the process. Here are the statistics:

.

  • 3½ hrs to complete with just the lower cabinetry. Call it a day for a full layout.
  • 85 Assemblies were created. I estimate 115 to 120 with the uppers included.
  • 666 Files created, with an estimate of 1,000 or so if the uppers are included.
  • 2 Errors in file naming were introduced (which could easily compound into more errors).

Inventor Tutorial for the iDoor – 22 – Finishing the Skeleton

 Add a .5′ dimension to the first line segment just drawn to fully constrain the sketch (an arbitrary number in this case as any number would work).

 

 Inventor Tutorial iDoor Page Twenty Two Image 01 - Ad Constraint

That’s it for the skeleton, now its time to create the solids. The first thing to do is turn on the visibility of all of the sketches except the Layout sketch. If any of the dimensions are visible, turn them off by right clicking on the sketch name in the browser and uncheck Dimension Visibility. Now rotate the skeleton into an isometric position similar to the one below…

Inventor Tutorial for the iDoor – 16 – More Sketching the Raised Panel

The arrow below points to the projected point, which is where you will begin the next line. Activate the Panel Profile sketch if it isn’t already, and begin a line towards the panel profile , but stop shy and click to end the line segment, and unless otherwise directed, always wait until you have a Horizontal or Vertical Constraint Glyph before ending a line. Now select the line just drawn and make it Construction geometry by clicking the Construction
icon on the Format Panel
.

The completed line should look like the one below…

The rest of the work on this sketch will be within the area, so you may want to use the View Face tool to select the YZ origin plane in the browser to look normal to the plane, then zoom in a bit.

Inventor Tutorial for the iDoor – 15 – More Sketching the Raised Panel

The end result of this pair of lines should look like the image below, and the status bar should report the sketch as being fully constrained (only while in sketch mode).

 

Inventor Tutorial iDoor Page Fifteen Image 01 - Skeletal Modeling Sketch

The reasoning behind the method used for creating this sketch this way will become apparent later, but for now, we need a bit more geometry to complete it.

Inventor Tutorial iDoor Page Fifteen Image 02 - Panel Profile Animation

As you should be able to see in the animation above, start by grabbing the Line
tool from the Draw Panel
, and hover at the top of the small vertical line until the green constraint dot appears, then click to begin sketching. Sketch over to the right a short distance, making sure the Vertical Constraint Glyph is present, and click to create the first segment. Continue in the same direction, and again go a short distance, look for the Glyph, and click to create the second segment. Now go up perpendicular tothe first two lines a short distance, look for the Glyph, and click to create the third line, and again for the fourth line. Now move parallel to the long bottom line towards the far end of same, and look for both the vertical constraint glyph, and the dashed line down to the end of the bottom line and click. The last line segment is to close the loop by going to the end of the bottom line where you hover the cursor over it until you get the green constraint dot and click. Right click and chose Done or hit Esc on your keyboard to exit the command. Save the file.

Inventor Tutorial iDoor Page Fifteen Image 03 - More skeletal model sketching

The sketch should now look like the one above. Now we need to project a point. Double click the Panel profile sketch in the browser to activate it, then grab the Project Geometry
tool from the Draw Panel
. Hover near the point at the upper corner of the stile profile closest to you until it highlights, then click to project the point into the current sketch. Now turn off the visibility of the Stile Profiles sketch to better see the projected geometry.
