    PCB Editor (Allegro) Get Distance (Dimension) Between Two Points Reply

    I want the edge-to-edge distance between these two pads, however whenever I select Dimension->Dimension Environment, then right click and select Linear Dimension, and select each of the pads, I keep getting the pin-to-pin dimension. What should I select in order to get a 'dumb' dimension?

     

    I realize that I could take the pin-to-pin dimension, subtract half of the width of the rectangles on either side, and obtain my measurement, but I'm sure there's a way to do this automatically and I just don't know it (yet!)

     

    Thanks!

    Do you want to know what the distance between the pads is, or do you want a dimension to show the distance between them?

    Distance between them, use Display>Measure, click on the pads in turn, the "Air Gap" will be the Pad Metal to Pad Metal distance.

    For the dimension, which version are you using? (The "Snap pick to" differs between versions)

    I'm using 16.6 Display->Measure, clicking on the pads, then "Air Gap" distance was the one I was looking for. If I DID want a dimension there, how would I go about it in 16.6? Thanks for the help!

    In Menu of 16.6 go to Manufacture>Dimension Environment

    RMB choose Linear Dimension. Use Find Filter View to select the items eg Pins/Symbols etc

    RMB choose Parameter option to change default settings including the unit of distance

    I don't believe the current dimensioning functionality has the ability to dimension the Air-Gap between elements (ie. Pins) to provide the same results as the Display > Measure Air Gap calculation.

    In the find filter select ONLY "other segs" and click on the edge of the pad.

     There is no straight forward way to measure the distance as you wish. You may want to keep the grids as small as possible and still aligning with the edge of the pads. Then in Display -> Measure select "other seg" in find. Now click at the edges of the pads.
