Adjusting patterns and dimensions with parameters

I'm attempting to make an adjustable, parameter-driven model for custom cubbies. My company makes cubbies for clients, but often work with odd dimensions. The goal is to be able to change inputs like height, width, cubby count in x and y direction, and (potentially), spacing between cubbies.

 

Currently, my dimensional parameters (height, width, etc) are working great, but if I try to change the number of cubbies in either direction the model gets wonky, especially if I input a number greater than I initially modeled with (ex. change 4 cubbies in x-axis to 6 cubbies). I made this assembly by modeling 1 vertical divider and 1 horizontal divider, and using the pattern tool to make the number I need. In the pattern feature I input parameters "CountX" and "CountY" for number to be duplicated. These are the parameters that break the model when I change them. 

 

Its probably worth noting that the overall assembly depends on dados to fit pieces together, so the number of dados in a specific direction needs to adjust with the number of cubbies. A similar problem seems to be happening with these when the "CountX/Y" parameters change.

It would really help if you could attach your model, then the forum users will be able to diagnois your issue easier.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save to your hard drive. Then use the Attachments section of a forum post to attach it.

As @jhackney1972 has already suggested, please export your design and attach it to a post. If it is an assembly with linked components then the public link to it might be more appropriate. The link must allow download and that only works if you are using a paid subscription. Otherwise you'll need to use the Web interface to export the design as a .f3z.

 

My personal gut feeling is that, in the end, Fusion 360 still lacks some important features to make this fully functional.

What I see in your design is an incorrect approach to achieve that goal.

The very first thing you need to avoid is to design with multiple overlapping lines. That means after the first outer rectangle, use lines only! That will ensure that you reference the correct line segments when dimensioning.

 

If you sketch and pattern all the slots at once right in the 1st sketch, then each time you adjust the quantity, you'd have to re-select all the necessary sketch profiles. That's not going to work!

 

Don't pattern in sketches when it can be avoided as in this case. Extrude the base, then extrude a slot. Pattern the slot feature.

To illustrate @TrippyLighting point, take a look at this simple model of a partitioned box.  Go into the parameters and change the Favorites and you will see the difference.

Thanks! I just tried patterning features instead of the lines in the sketch and it works flawlessly.
