fusion 360 error constriants and dimensions

[oystein.l.l]

hello! so i have an issue making a frame where it says error constriants and dimensions when trying to change the width of a dimension and i cant seem to fix it just wonder if you guys know how to fix it? im a new beginner that might be why its complicated program, theres a video below.

the error tells you exactly which dimension is the problem:  d125, with a value of 100:

find that dimension in your sketch, and delete it.

If you want more help than that, share the model.

can i send you the 3d files ? i think i know the dimension but then i cant change the width of my arm..

[jeff_strater]

yes, export the file as a "Fusion Archive", and attach it to a response here

thank you for reply! heres the files 😉 archieved files as you requested.

here is d125 - the easy way to find these is to look for the value.  In this case, it is 100.  Then, just hover over dimensions with that value, and the parameter name will appear in the popup:

However, I notice in this design that you have a lot of other sketch warnings, primarily lost references to projected geometry and the sketch plane.  It is not a good idea to allow those to remain.  You should try to fix those warnings, as well, as design intent is lost.

thank you so much 🙂 yep im pretty new to this started 2 days ago... i will see if i can fix other issues too, 

the issue is i want to change the width of d125 100m to lets say 150mm but it wont let me any advice ?

and if you can tell me how to fix those warnings ? i see 2 warnings sketch plane lost, so i can learn and use this if this happens again

I figured out how to do it pretty simple you just use timeline to Edit the errors 🙂 thanks for help! I can now change the dimensions of the Frame Arms, im just wondering how do you change dimension of the whole arm? any suggestions ? im stuck...

Whole Arm - to how big?

For error and warnings, fix them when you see them straight away, with Undo.

Figure another way to get it done without errors.

Best not to use Delete, when you get a warning box - unless you know how to fix the errors.

Might help.....

i had to make a new sketch i couldnt change anything without it deforming or having to redo alot.. 

everything works fine now i also got rid of the timeline errors... yes i noticed when you delete something it doesent really delete...
