Parameter management frustrations

Parameter management frustrations

Let me start by saying I love Fusion 360. I'm a long-retired developer who needed a CAD program to support my 3D printing hobby. I've dabbled with CAD over the years, to plan a sprinkler system decades ago for example, but never found it enjoyable. Until now.

 

But as much fun as I'm having with F360, I'm frustrated by puzzling limitations and omissions regarding, especially, parameter management. Is there a beta program I could join where I'd have some input in this area?

Hi,

Can you please be more specific about your position.

yes, please.  More info.  Glad to you hear that you like Fusion.  And, admittedly, there are some missing features in parameters.  Some that are on our list:

  • filtering and maybe sorting in the parameter dialog (sorting is not quite so obvious, because of the way model parameters are grouped...)
  • search in the parameter dialog
  • compute suspend in the parameter dialog - lots of frustration around Fusion updating after each change, each of which could take some time.
  • using driven dimensions in equations (yeah, we know...)
  • better units handling.  Fusion is too strict around units balancing, requiring a lot of "*1 mm" in equations.

if you have more, do let us know.  No guarantees, of course...

Sure. I use parameters heavily; they're one of the major attractions that led me to settle on Fusion 360. But the program provides no way to manage them other than to view them in a long, unsortable list. This is fine as long as you don't use more than a few - but using only a few defeats the purpose of parametric design!

 

Although my initial interest in F360 was designing parts for 3D printing, I had a more pressing need. My tiny lab/office is in need of serious reconfiguration. I want to be able to use every cubic foot of space as best I can - kind of like I saw space used back in my submarine days.

 

My office is in the basement of a tri-level, and is about a third the size of my previous space (a large bedroom). It's oddly shaped and the lower half of the room is narrower and shorter than the upper half due to the foundation. I only have one 'normal' ceiling-to-floor, planar wall.

 

I need to design a couple of platforms on heavy duty overhead tracks suspended from the ceiling to take advantage of the recessed areas and make things accessible from the bench. I need to exhaust fumes to the outside, and bring some fresh air in as well. I need to design storage to fit in odd spaces and under my benches, which I also need to design.

 

I've watched a lot of training videos, and I  (try hard to follow) Rules One and Two. F360 could help with naming if it had a field in the creation dialogs or, if there is no creation dialog, a dialog that pops up when a name is appropriate. Enforcement should be an option.

 

I have many assemblies, each with multiple components or nested assemblies. I'm a couple (user defined) parameters in, and I can't keep track of what's where. My understanding was that F360 was a ground-up new design rather than a conglomeration of other bits glued together. That being the case, I'm baffled that the designers, who presumably have some dev experience and should live and die managing variables of one sort or another, put everything in the global namespace!

 

It only makes sense that if I have a hierarchy of components and assemblies, that names I create while working in one assembly would only be visible to that assembly and its children. And when I'm working with parameters, I should only see those that apply to the object upon which I am working.

 

This also applies to names that appear in the browser. I still haven't figured out why I sometimes get one or more (digits) after a name and other times not. For example, if I have assemblies 'A' and 'B', I should be able to but a component 'C' and 'D' within each.

 


But what I get is 'C' and 'D' in one, and 'C (1)' and 'D (1)' in the other. But I think this doesn't always happen. Apparently under some circumstances I can have the same name in multiple places and in others I can't. Does it depend on order? Or on what I've done somewhere else? Beats me! But the point is it should never happen - what's inside 'A' is A's, and what's inside 'B' is B's.

 

I should be able to get an overview of all objects in my design in a single window. The list should be filterable and sortable by type (parameter, joint, etc), assembly, component, dependencies, name and so forth. I should be able to print/save the resultant list.


The list should NOT be modal, so I can keep it open on one of my screens. I can't tell you how many times I've had to open the parameter list to check some detail of a parameter, then close it again so I could resume work.

 

I'm sure there's more, but this is a start.
