sketch question

[uwam2ie]

there are some helpful things in nx sketcher to lock (mb3) or (alt) key to free constraint creation. Also there are buttons to control the behaviour. My question is - using the alt key inside line creation free the automatic constraints fine... but it frees the point snap as well. Is there a way to free only the constraint creation - not the snap points ?
thx in ad

Yes there is a way to turn off the dynamic sketch constraint creation. You can turn them all off or only particular ones off, and leave others on.
You probably do not have your sketch constraints toolbar turned on, you should be able to figure it out from there.
I am not at work right now so I cannot give you step by step instructions.
It would be best if you specified what version of NX you are using.

Yes, there is a toggle button, labeled 'Create Inferred Constraints', which when toggled OFF, will be the same as when you hold down the 'Alt' key during a single curve creation, only it remains in this state (of not creating any constraints at all) until you toggle it back ON.

Now there is another Sketcher icon labeled 'Inferred Constraints', which allows you to set which types of constraints you wish the system to infer when adding curves to a Sketch. If you wish, you can toggle OFF any and all individual constraint types which you wish NOT to be created automatically. This, along with either the 'Create Inferred Constraints' toggle or the 'Alt' key, are the only real controls you have over what and whether constraints are inferred during Sketch curve creation or not.

thx for answers,
I know all that you said - It would be nice to have the point snap on when the constraints are deactivated from the alt key.
I thought there is another nice key to pull...
or must I do an ER?

You may be able to set something up yourself.
Here is a thread to get you started:

There are accelerators that are already set up in NX, and a way to customize them yourself. It has been quite a few years since I went down that road, but I know it can be done.

The issues isn't that Snap Points are not 'enabled' when holding down on the 'Alt' key, it's that making them coincident requires that a 'constraint' be created and therefore with the 'Alt' key held down the Snap Points are not retained.
