Plane alignement on different surface levels ?

[Mranaskw]

Hello

I have seen a programmer creating a plane on a surface from different levels , the first point was on the highest level of the part , the second one was on the other medium side , the last one on the lower surface , i asked that the plane should be in the same level but he answered that the points have the same Z , What the heck does that mean , he even proved it in the scripte (before doing inserting alignement) i saw the probed points with same coordinates , can you please explain cuz im having a brain storm hhh

Maybe he’s creating a mid-plane per print call out.

An offset plane.

what is the diffrence between it and the regular plane and why does it have the same Z coordinates ?

[jozey]

something doesnt sound right here... no way all three planes in different Z depths have the same Z coordinates.. ask him how he is doing it

An offset plane would be used if a blueprint gives you datum target points for a plane and those points happen to be at different Z heights. You'll see this type of call-out on castings, molds, or fixtures where certain points are "contact points" for a mating part/assembly.

Go into Construct/Plane..select "Offset Plane".

Here is an example straight from the 201 book:

OR, offset points and then the plane construct, this would give 3 points with the same Z value.

Often used for machining locators defined on the print or chosen in machining fixture build, the setup guys will be interested.

I would use DAN_Ms option 1 in my day to day

OR, offset points and then the plane construct, this would give 3 points with the same Z value.

But do note that "offset points and constructing a plane" doesn't necessarily create the same thing as "constructing an offset plane from three points". In the first case, offsets are done in the current coordinate system while in the second, offsets are done perpendicular to the actually constructed plane.

Noted, sir!
