Why are sketch objects I create sometimes getting locked? Little red lock icon

rickjohnston · ‎07-01-2020

Hi All.

I am starting to have an issue when creating sketch object that they get "locked" depicted by a little red lock icon on the sketch name? I am then not able to edit the sketch in any way.

I have it somewhat narrowed down but I may just be just really guessing that it happens when copying and pasting sketch object and/or when I use Create sketch from a face. I have this long detailed sketch object that starts extruded from a base sketch. I then need to modify and do not want to recreate a new sketch object at the next transition so I click the face and click Create sketch and it creates another sketch at the plane I need to transition. I simply wish to slightly modify the new sketch but I cannot offset, move or anything because I am assuming Fusion has locked it but why? How can I simply "unlock" the sketch object?

TIA!

That little red push pin beside the sketch in the browser does not mean the sketch is locked. It means it is fully constrained with sketch constraints and dimensions. As to not being able to edit a sketch, please attach a model so the forum users can take a look for you.

Edit: Red pin or not, you should be able to right click on the sketch in the timeline and choose Edit.

Thank you.

It is not allowing me to edit. As a matter of fact the sketch appears strange in that it doesnt show line work that comprises the sketch as other I created manually? So I think sketch 82 in my model created with 'Create Sketch' off the top face of the stanchion is the issue for not being able to edit? I can select "hidden" lines but cannot move them. As a test I simply moved all sketch objects and the associated body from original position down 8000mm (I'm actually working in feet this is a real-world sized stanchion). The sketch 82 object I cannot move and I cannot edits lines I want.

All I really need to do is move the 5 vertical lines in 4 ft (1219.2mm) on both sides (see screen capture)

~~Somebody turned off Capture Design History - never a good sign...~~

~~Looks like someone moved the sketch off of the sketch plane. Uh oh.~~

~~No dimensions?~~

~~No horizontal constraints?~~

~~No vertical constraints?~~

~~Missing most coincident constraints?~~

~~Also, it is generally a good idea to work close to (at?) the Origin.~~

~~I recommend starting over on this one.~~

Edit: Never mind - I just don't understand your workflow - it is very different than the way that I work...

There is not much in this model so I would definitely start over with a NEW file. I also would turn on Design History (timeline) so you can have better control over your model. Concentrate on simple, fully constrained and dimensioned sketches. There is little point to spending much time on the attempted recovery of this file.

Thanks. I deleted everything to keep it simple and not complicate things. I had to turn off design history because in this model I started with a mesh and it needs to be turned off for some reason?

NOTE: I've started this model over twice now. I think it is related to 'Create Sketch' from a face. Every time I do that command the same thing happens...at least on my Fusion install.

Edit: I deleted the constraints thinking that was the issue so I can recreate them later. Also definitely the 'Create Sketch' on a face. Ran simple test of a polygon a circle and a rectangle. Extruded each one and then did a 'Create Sketch' on a vertical and horizontal face. Sketch is created on the face representing the shape but they all get created with the little red lock icon. Those are the only sketch objects I cannot edit in any way. Create a manual sketch and no issues.

Thanks again!

Then you can turn it back on to continue working.

Let's start from the beginning.

Import you mesh and Attach that file here for next step.

Just an update so I can close this out.

I am guessing this is "as-designed" functionality. It is 'Create Sketch' on a face so what I am assuming is happening is the sketch is locked to the face it was created from and thus it cannot be modified in any way. It can be moved and copied as long as Object Type in the dropdown is 'Bodies' not 'Sketch Objects'. It is not directly related to a mesh object as I first thought as I started a new design without using Mesh add-on and created objects and extruding them using the 'Create Sketch' on a face exhibits same behavior.

Thanks again for the input I appreciate it.

Thank you for the EXPERT explanation

How about:

- How do you fix it

- what does Fully Constrained mean

- How do you prevent it.

Some of us paid money for this seemingly useful tool

Not all of us are Experts (kinda why we are here)

1. Autodesk Expert Elites and not Autodesk Employees. We are paying customers, just like you.

2. If you don't know what constraining a sketch means then my recommendation would be for you to complete one of the Fusion 360 courses that you can find directly from within Fusion 360 in the "Self-paced Learning" section.

3. Fully constraining and dimensioning a sketch is recommended. There's nothing t fix 😉

this literally feels like me talking to my cs professor and he answers back w something that needs more explanation, I learned early that you dont ask a STEM major "how to do something" you ask him about a project he's working on or has worked on in the past and try to steer him in the right direction, these ppl were meant for RAW COMUPTING, and not a healthly communicative relationship. And if you find yourself asking a seemingly basic question on a forum best expect to not be helped at all and or have someone refuse to answer your question correctly or comprehensively

Even though I understand that people who answer questions are "paid users"(or not) just like the rest of us, that does not give them the right to be blatantly arrogant!!! If you don't want to help, just simple DON'T, instead of making people feel like idiots for having asked for help to begin with!!!!!
Fusion 360 is a great product but it is FUL:L of problems and OVERLY complicated to lear and use. Just because some users are more proficient at it, it does not give then the right to belittle others who are trying to learn how to use is and may have more difficulty in doing so!
Pointing someone to tutorials is just arrogant and wrong!!!!

These tutorials were created by Autodesk to help YOU learn the basics of the software, including constraining sketches.

They form the basis of further questions, which I am thrilled to answer.
