reverse normal direction on a datum plan

how do you do it. when I need to flip the normal direction, I can't do it

• Re: reverse normal direction on a datum plan

If you select normal to twice it will flip.

how do you select normal to twice ?

• Re: reverse normal direction on a datum plan

Select normal to once and slect normal to again.

• Re: reverse normal direction on a datum plan

but that's just it.. Where do you find the once/twice ? I have looked in properties and I don't see it anywhere

• Re: reverse normal direction on a datum plan

do you select the datum it's self ? and do it there, what are the steps ?

Hi Dan,

SolidWorks does not have the ability to flip the normal direction of a plane directly. However, for most things in SolidWorks, the normal direction does not really matter because you the feature/action that you are taking on the plane has the ability to flip.

For instance:

• To view normal to the back of the plane, as Tony suggests, select the plane and use Normal To (from the context toolbar, regular toolbar, etc.) and once it goes normal to the plane, just hit Normal To again and it will flip the other direction.
• To extrude a sketch on a plane in the opposite direction, you use flip direction in the extrude definition.
• To flip a sketch that is on a plane so that it is on the opposite side of the plane (basically as if the plane normal were flipped before building the sketch), go to Tools, Sketch Tools, Modify and right click on the origin of the little black origin indicator that is shown. The center of the origin mirrors about the origin (identical to flipping the normal) while right clicking on the little circles at the endpoints mirrors about the x or y. The Modify Sketch command modifies the entire sketch with its origin, not just the geometry within the sketches 2D coordinates.

If you can indicate exactly why you'd like the planes normal to be the opposite, there is likely a way to achieve the desired behavior without actually reversing it.

Thanks,
Jim

Jim,

I think that's it... I don't want the orinatation to change before I start a sketch on the datum plan, this might work
