Constrain extrusion to origin - sketch is already constrained . . .

[Anonymous]

Folks,

I've sketched a centerline rectangle such that it is aligned to the origin of my part file.  I can't move the rectangle sketch off of the origin, so it must be aligned, but I can't find anything that actually indicates this relationship - so as far as I can tell - this alignment is somehow implicitly made by the software.

The issue that is baffling me (well, OK, one of the issues) is that the extruded body made from that aligned sketch, can easily be dragged off of the origin, as if the alignment that is inviolable in the sketcher, no longer exists as soon as the extrusion has been made.  This is unexpected behavior to say the least, and as much as I've poked around the forums and looked at the (non-exisistant) F360 documentation, I can't figure out how it is possible that this geometry can move off of the origin considering the sketch can't move at all.  This is the sort of baffling behavior that the F360 evangelists will explain away with some sort of convoluted logic that F360 seems to warrant, but anyone coming in from ANY of the other mainstream CAD packages will not understand.  F360 PM's, being different for the sake of being different is not a benefit.  Look at mainstream MCAD and emulate the workflows.

Although I'm a paying F360 customer, I consider the package a joke and completely not ready for prime time for a real parametric 3D MCAD (e.g. Solidworks, NX, Creo, Inventor, etc) modeling user.

I look at the essentially useless set of features that are added in each of the update releases and shake my head.  F360 product managers- for lords sake - stop adding more sugar, fix the glaring deficiencies that make the product useless for the majority of MCAD users.  I defy anyone using F360 with X-referenced assemblies to say the product is a release grade product - it is not - the complete inability to manipulate an assembly or component by simply right clicking on it is a gigantic waste of time and is pathetic.

Similarly, the glaring errors in the modeling environment need to be fixed for the product to ever be viable for the majority of MCAD users that F360 is wooing.  

Sorry for being harsh, but I've been using this product for over a year and am growing more and more impatient by the lack of ability of Autodesk to drag it to the point of being usable for the bulk of the MCAD market.

Every solid modeler I've used has an automatic constraint added if you pick the origin when drawing curves and they never show the constraint, don't know who started that rule but it's in a lot of solid modelers.

There are a few ways to delete the constraint I'll use the rectangle as an example, right click on the point at the origin and you should get a menu with Delete Coincident, just delete and the rectangle will be free to move.

Fusion allows you to move bodies or components, if you want the sketch to move with the body then work with components. For every part in the design create a component and with it activated make all the sketches and features, keep the component totally self contained and when you move the component all features will move with it.

Hi HT,

Thanks, that did the trick!
