While laboring away on this fine Monday morning, an idea struck me that could be incredibly useful for Inventor workflow (Or at the very least, how I use it). Namely, with making large compartmentalized assemblies/frames that need to be stuck together and otherwise match up, I've been leveraging making part files that exist only of sketches, and deriving specific sketches out into various parts. One good example, making a large cure oven with a frame created through Frame Generator and split into 4 main components, the oven frame, the support frame that it rests on (So we can disassemble it for shipping/installation), the cooldown section (Also removable), and the catwalk (Again, a removable, separate section). I've found that for applications like this, especially when they're really heavy on the Frame Generator, the most effective way to work was to make all these dependent sketches as one large .ipt with no geometry, and making derived parts carrying over the sketches that are needed for each section, which I then throw into an assembly to build the frames. There are a few problems with this method, and places for improvement, so what I'm thinking would be a good addition would be an Inventor file type that exclusively consists of sketches and work features, it might make more sense to outline features I feel would be important. For most purposes, is treated like an .ipt, but without the ability to do any '3D Model' commands However, treat sketches made in it less like features in a part, and more like parts in an assembly, ie. Folders, because making these huge sketch parts turns into a real mess when each "entity" may have multiple sketches to define its parts (Especially when using a combo of 2D and 3D sketches to make up for how finnicky 3D sketches can get), also being able to change visibility of entire sections would be nice Being able to 'derive' the various sketches into regular .ipt files, so they'd work as a regular sketch part would anyways. Heck, it might even be worth to translate every sketch included in the derive into a single 3D sketch for ease of use. Color overrides, while yes the formatting is nice, being able to set an entire sketch to just use an override for their "fully constrained color". Because contrast is a wonderful thing, but changing line format is nowhere near as useful as it could be since it also overrides the color of projected lines and the color applied to non-fully constrained lines, which are both pretty useful. Performing rectangular/circular/mirror patterns on entire 2D or 3D sketches, because what little pattern methods are available to sketches is still lacking compared to what can be done at the part level In that same vein, allow assembly-level feature patterns to use sketch components (Or blocks, or points along a sketch, I really don't care) as their feature to follow. I say this because feature patterns seem less fluid as they could be due to the fact that they can only pattern along geometry, and not say, a well-defined centerpoint or something of the like Being able to constrain straight to the sketches, pretty much like what can be done with 2D sketches, but extend to be able to do so with 3D sketches in the part as well. Because using 3D sketches to outline piping runs and whatnot would be much, much faster and cleaner if every point didn't have to have a work point and every line a work axis just to be able to place components along the guidelines For Design Accelerator assemblies, an option to take the color of their defining line would be very helpful too, as I've found that it's easier both on the design and fabrication side to use colors with large framework, ie. All outer frame is colored blue (With lighter hues indicating thinner tube, for at-a-glance identification), floor supports being brown, ceiling being red, wall supports being different colors unless their symmetric, etc... Same goes for tube and pipe runs though they might actually match their design color. I'm sure I can think up more, if not a way to do this on my own if I can hook into Inventor enough if Autodesk doesn't seem interested.
