Personal version: Is there a limit to the number of components, or variables ?

[m_schweter]

New user, making progress, still can't get some functions to work reliably [user error, I suspect! 😏😉], but I HAVE been able to successfully design the components.
However, I've run into an intractable issue.

Project successfully auto generates component dims from three variables, instead of drawing each individually, duplicating an existing set of 1960's drawings, and by extension solid bodies.
[forced perspective, the dims are scaled linear, but, each sketch in the component has a different linear formula, so copy/resize body won't work.]
I wanted to auto-scale & locate the components as there's 10 of one version, and 15 of a slightly modified version in total, that need to align linearly.

1. Generate a component, fully constrained (as far as I can tell ), dimensions all calculated from three variables (HoldingVars).
[HoldingVars are in a sketch, and sourced from USER Variable table, and referenced by name, STA1, STA2, etc.]
[ HoldingVar | varName |mm| STAn | value ], HoldingVars are Back, Front, Next
[ DimensionVar | varName |mm| nnn * HoldingVar + nnn | value ] for all sketches, extrusions, etc.
2. COPY/PASTE NEW, rename NEW, edit the three HoldingVar STAs, to scale and place the component.
3. COPY/PASTE NEW/Edit HoldingVars works for an additional three cycles [five total components]
4. Sixth component FAILs when attempting to change the three HoldingVar's STAs.

I get split, extrude, and loft error messages, and red highlighted timeline entries.
I do NOT get any warnings or errors on the first five copy/edits.

I did notice the internal names of variables were getting quite long (varName_2_1_1_1, etc.) so did some experiments.

Deleted all but two components, copy/paste new then in each copy Fusion renamed OK (varName -> varName_2, etc.) and I kept using the first component to copy/paste new.
(varName -> varName_3,varName -> varName_4,etc.)
Still got the errors and warnings on the sixth component when editing the three HoldingVars.

Finally, deleted all but the original component, attempted to edit the component's HoldingVar STA, and also got the errors.

I am at a loss for what to try next.

Thanks for listening - Mark

Please attach the model you are referring to in your post.  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 as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Hi,

Please upload a concrete example with explanation for evaluation.

Thanks for the prompt replies!

I found the issue...

Whilst getting ready for work, watching a Fusion360 tutorial, not thinking of anything in particular...
*PoP!* into my head...
The issue was there's a split-object done to clip the portion of the ring's outer circumference (?) that's below the " floor" early in the timeline.
The root cause of the error was Ring-6 (and after) don't intersect the "floor" plane so the split function fails.
(No intersection between object and cutting plane)

If I had a different order of operations, it would have been easier to spot.

Thanks again!!
