However, this tip is one that I have found useful on a few occasions, and not one that everyone knows.
That tip? Suppressing instances in an assembly.
Recently, I've been working on building an Autodesk Inventor model of a Pie Safe. One of the features of this type of furniture, is a door made of perforated tin, which allows for airflow. To be decorative, these perforations often formed into patterns.
So for my model, I decided to create the perforations in the form of a Celtic cross. And yes, I intended to model the perforations.
|The cross I'm using as a pattern|
First of all, I found an image that I could use, and placed it on my sketch using the Insert Image tool.

Next, I placed a hole on the center of the image, and used the Rectangular Pattern tool to create a pattern inside the image.

Now, I need to begin suppressing the holes inside the pattern to match what I want. I choose the instance of the pattern I want to suppress, and choose Suppress Feature. Out of curiosity, how many knew this was possible in a pattern?

|Adding some circular patterns|
|The image suppressed. I can use this to fine tune the pattern.|
After a little more fine tuning, I think I'll have something I'm pretty happy with!
