  • Line to line linear distance

    If Line to Line linear distance is not parallel to X or Y axis, I need to know how it would be measured. Please, let me know the procedure.

    Just make an alignment that makes them parallel. Report it, then recall your original alignment.

      Effective, as usual

    When you create the dimension, there is a checkbox called "To Feature." Click that, and then there is another checkbox below that to measure parallel or perpendicular to. Click the perpendicular box and you should get what you want

      That will only give the result from the centroid of the line, to get the two end points create 2 feature sets and get the line hit points then do as you say,

    It's the shortest distance between lines, the lines mustn't be parallels (because of the cross product !)

    Do note that distance line <-> line, to feature, treats the second line as the datum line, and calculates a perpendicular distance from the cast point and end points of the first line, so depending on the order, you can get very different results for both MIN, MEAS and MAX, especially if the lines are of different length, or not directly opposed.


    That's OK if one of the lines actually *is* a datum line, but if not, you can get slighty 'better' results by creating the mid line of the two lines, and add that as a third feature to the dimension. This third feature will be the datum, the distance(s) will be calculatet perp to that. MEAS will now be the same irrespective of the order of the first two features (MAX and MIN will still vary, unless the endpoints are exactly opposite).


    Never forget, in *theory* everything looks like a) below, but in our physical reality it's always like b) - more or less, but still b).

    I always used to tell people. CMM's were designed to measure perfect parts.
