Automatic Sketcher Reference Plane

Creo2 M120

 

When creating a sketch, Creo will sometimes automatically select a reference plane.  Many times that isn't the plane I want to use, so I always go back and check it.

 

Is there a config option to force Creo to prompt me for a reference plane?  I searched the config editor and came up empty.

    For what it's worth, the config option enable_face_preselection can be set to no to disable the preselection thus forcing you to choose both planes. Unfortunately, I don't know of an option that will only force selection of the orientation plane.

    Doug,

    Creo always prompt you for the reference plane when creating a Sketch.

    Actually, there are a couple of ways to enter sketcher without a prompt for a reference plane.

     

    1. If you select a plane and then select a command like extrude, Creo goes straight into sketcher with no ref plan prompt.
    2. If you select a command like extrude and then select a plane, Creo goes straight into sketcher with no ref plan prompt.

     

    Those are both handy workflows, I'd simply like to be presented with the sketch setup dialog every time so I can very the reference plane that Creo has assumed for me.

    This issue of automatically selected sketcher reference bothers me too (double work to have to go back and re-select). With everything being parametric, I've been caught too often with inappropriate sketcher references.To be prompted for the sketcher reference for me is a must (how is Creo to know MY intent?).

    So what work flow procedure (and settings) is required if I want to ALWAYS be prompted for the sketcher reference?

    Hi Doug, this catches me out time & time again. I think there is a quick route to sketcher where only one reference is needed & the second is automatically selected as you stated, usually not the one you want. In my experience, if you have a datum plane already selected going into feature creation, then that datum becomes your sketch plane & a second reference is automatically created. If however no datum plane is selected, & you work through the sketch plane setup by selecting 'placement', then 'define' sketch, then you will be prompted for a second reference. I could be wrong, but i think this short cut to sketcher environment must have started in Creo 1, it does not appear to have this behaviour in Wildfire 5.

    Regards

    John

    config.pro option :"sketcher_auto_create_refs" set the value to "zero"

    this is in creo 2.0

    I have that set but it has no impact on the sketcher reference plane.  It only prevents Creo from adding default references inside sketcher.

    This is closer, but not much. By setting this option, Creo will not let you pick the plane before entering the feature.  So if I choose a plane and then hit the extrude tool, Creo presents the sketch setup dialog - with nothing selected.  That's better.

     

    However, if I hit the extrude tool and then select a plane, Creo goes right into sketcher, having chosen the reference plane for me.

     

    I've created a product idea to add an option to control this.  Please vote for it here.
