what does this mean: " sketch is fully constrained"

[cekuhnen]

I followed the video also activated preview sketch in preferences but cannot replicate the same visual color changes for sketches.

How is this supposed to work? The video does not really explain the ideas behind it very clearly. It mentions great feedback but what feedback?

@kellings

Evvery tried to connect two splines add a G1 G2 constraint dimensioned the handles and then later needed to adjust the handles but maintain the shape of the

previous curves? Honestly that is a nightmare in with the sketch engine in Fusion 360 compared to the blend curve function in Inventor or well how all other surface

modelers like Alias Rhino MOI SolidThinking and what not work.

However I like the ability to constrain sketches that part works well for certain needs. But Fusion sketches cannot satisfy all the needs I have as a product designer

because it is too mechanical in nature and lacks fine control over curve profile creation.

For example CV curves are missing. Splines are fine for 2 3 poitns but then they became a nightmare to work with where a NURBS curve is easier to massage.

So I see simply the need to get CV curves and blend curves finally into the toolset and make that work with the 3D sketch engine. Thsi would be a terrific workflow

because you combine to approaches in one app how surface modelers and how solid modelers sketch.

well I have found how to make a drawing go wrong I will screen cast it, plus you can lock down a drawing with not grounding it I just have to see if I can do it again this is fun

[daniel_lyall]

both picks are constrained and cant be moved they are not grounded, if you remove the dimentions from the drawing above only two lines are constained 

if you start a drawing a rectangle shape from centre out the two lines that touch it will be constrained the other two lines wont be you cant move it but the two lines that are not constrained you can move and the constrained line`s will move with it, dimension the other 2 lines then they become constrained and the drawing is lock down.

dimension from centre to drawing to 2 or 3 points will constrain the drawing and lock it down.

dimensioning from centre to 1 point two lines will be constrained the other lines wont be and you can move 2 of the lines around and the drawing is locked to centre.

remove the dementions from centre to the drawing it becomes un locked down and it can be moved, if its is from centre it is stuck in place you can move the lines around but not move the drawing.

if a drawing is fully constrained it cant be moved if the constraints are remove it can be moved, then if you ground it it`s grounded being constrained or not.

this is the mad screen cast

ops thats a nice bug lol

here`s one more

Some good observations there.  In that first screen cast, I thought we were leaving earth and heading for a mars mission 😉  The way that shape jumped to crazy dimensions, is a perfect example of where I would temporarily apply a Fix/Unfix constraint (will make the point turn green I believe) to a corner point that was jumping around wildly like that, so that it is grounded while applying the desired constraint.  Once applied, remove the grounded point by using the Fix/Unfix constraint again. 

Regarding your second screencast, what's going on there is the lower left corner was snapped to the origin point, which is grounded.  To remove this, select the point at the origin, right click and select Delete Coincident.  That will remove the invisible coincident constraint the point has with the origin.  Note that if there are multiple things snapped to the origin, will need to hold the left mouse button down while selecting to get the "select through" list and go through and check if there is a Delete Coincident option for each point.

It's nice that a purple projection point now shows up when snapping to the origin, reminding you that are making a coincident constraint to an "outside" geometry so to speak.

I think that is where I am having some of my difficulties. It's been so beaten into my head that step one is to construct your sketch relative to the origin, now that isn't the case as much. I have to unlearn a bit. I wouldn't doubt that my Inventor experience actually hinders me a bit in Fusion."

With the overconstraint bugs fixed, snapping to the origin should be fine.  It's just not a necessity anymore, and therefore is not an additional detail that needs to be introduced to someone just learning (it is important for them to be aware though of the grounding that occurs when snapping to the origin, as Daniel just illustrated).

I can not reproduce the issue. Could you please attach the f3d file?

thanks

[daniel_lyall]

what one the first one I new would happen, it`s something I have done before just not to 50000 mm the secong one is 4 lines the first starting from origin ending back at origin. I did not keep any of the files I was trying to make it go mad.

the constrants are fine (fixed) if you use the correct one`s  I will see if I can do it again.

@Anonymous Once it is out of PREVEIW, this will eventually be a fully functional feature that you can turn on in the preferences dialog should you choose it is useful to your particular workflow. 

@kellings "And that is their challenge. I really don't understand what you just said (yeah, I get the gist of it, but I'm no expert like you are). I don't envy them making a tool that is simple enough for everyone yet also has the functionality that power users need without adding the complexity." This is a conversation we have everyday on the Fusion 360 team. How do we accommodate users who have never used a CAD-like tool while not  hindering our power users.

Once again I thank you for all your feedback as we continue to improve your experience.

@jiang_peng

did it again vid pic`s file

it did not happen streight away had to try 4 times to get to go mad it`s a random bug

Maritza, that sounds perfect.  I will introduce this optional feature (that is also currently under development) in an intermediate "level" of the educational system I mentioned.

I truly applaud all of you for undertaking with Fusion 360 the noble challenge on multiple levels of considering a wider audience and not accepting traditional assumptions (including not writing off many "unconventional" users, nor assuming such users are incapable of developing into using more advanced concepts, with the right guidance).  The vision is truly inspired, the effort very clearly shows, and there are lofty and far reaching societal transformations in the works because of this unique commitment.

Thanks!

everyone from old timer`s to kids are useing fusion 360 now it`s more that it is a package that can be use by many levels from the machinests who could just write out the gcode to do high order stuff and they can do the same thing just better with fusion hell to do a cam op it can be done in a couple of clicks and it a fancy tool path, they have got it prity much right with fusion the program it self the learning material is still not that grate but it getting better.

and you can do the same stuff with fusion as something that cost 10000 plus a year there are a couple of thing that still need added for me V carve, nesting and drag knife.

and they let use try and kill there program to find the bugs what`s fun to do if they did not I would say the price would have to go up as staff and machines would be needed to do it.

its something I dont have a problem with as they are letting me use it as I see fit at no cost so to give back me kill fusion.

[jiang_peng]

I can reproduce. Will look into it. Thanks

[Anonymous]

Yep, it's a whole new ball game we're entering 😉

[daniel_lyall]

@jiang_peng have fun 

@Anonymous yep sounds like you are going to help lead the way

[daniel_lyall]

@ jiang.peng have fun 

@ jjurban55 yep sounds like you are going to help lead the way

[Anonymous]

Hmm, that would be nice 😉  Maybe we all can help lead the way, some day...or today.  Let's see, it sounds like you're really good at putting stuff through the wringer, maybe I could send one of the machines to you to kick around a little (except I forget, are you all the way in Australia if memory serves me?).
