Is this normal?

When I measured the 20 mm dimension using the caliper tool, it read 20.37 mm. However, when using the Cartesian tool, it showed 58.41 mm. This is the only dimension that the Cartesian tool is not reading correctly.

Cartesian distance measures from the mid-point of Feature 1, perpendicular to Feature 2. 

I am not sure about the Caliper Distance, and but if you search the help for Caliper Distance, it may give you the answer you're looking for.

Hi 

 

some reading about the cartesian distance

Tom,

 

don't know about caliper distance, but it seem interpreted in "base aligment" in this case. I guess  Plan 2 and plan 47 are not parraleles

If you create a perpendicular from the construction drop down menu using the same two planes, you will get a visual of what the cartesian distance is doing.

I created the perpendicularity, and the 20 mm checked good, but the cartesian dimensions still checking wrong. Thanks for your response.

For that constructed perpendicual you have to look for "Depth" and that's the same as for Cartesian distance.

I'm afraid you have something wrong with evaluation.
Open both planes and look for vectors/angles - there must be something which will tell you what is wrong. I bet on that small plane.

So, you have done goog job :)

Ramiro,

perpendicular and cartesian distance are same thing.

in such case, ask cartesian distance from plan 2 to plan 47 , and from plan 47 to plan 2. If there are not the same, it tell you the two plan are not parallel , ask about planeity for each plan, if there is a plan which have a very big planeity, check and verify it's "palpage" (hole in the material, colision, "talonnage" ...)
