    Component seletion and zooming Pads viewer

    mdtaylor

      Hello, I am an engineering consultant and long time OrCAD/Allegro user. I have started a new contract and the layout person is using Pads PCB layout tools. I am trying to use the Pads viewer to check the layout but I am finding it fustrating after using the Allegro viewer for many years.

       

      Here are my issues, maybe someone can let me know if I am still fighting the learning curve or if this is the way things are:

       

      - When selecting a component by clicking the reference designator in the 'Project Explorer' the component is highlighted and the window zoom so the component fills the window. Why would I want the window to zoom in that far? I would like to see the component and associated routing or components around the selected part, any way to just hightlight the component?

       

      - Once the window zooms in on the component there is no way of easily zooming out, no '--' (minus) button.

       

      - Zooming in general is difficult, zoom button is awkward, no '+' (plus) or '--' (minus) buttons, can only hit the 'Board <Home>' button and try to zoom in on what you want to see.

       

      Any suggestions?

          Mike - I am going to move your post to the PADS Layout and Routing community. I think that will be a more targeted area for your questions. You should receive an email notice to this effect. Thanks for the post.

            It is true the zoom to selection does zoom in very close.  To zoom out further deselect the component by left-clicking on the board - in an empty area so you don't select anything else.  Then with the cursor near the component hit the Page Down key a few times.  This will allow you to see the surrounding circuit.   I use a trackball that does not have a convenient zoom button and have found the Page Up and Page Down keys very useful in PADS.

              In the Project Explorer, right-click on the component and un-check Zoom to selection. When the part is selected click on it with the cursor and then use the page up and page down keys to change zoom. Scrolling with mouse wheel can also zoom in combination with Ctrl key. Press down on the mouse wheel and moving the mouse to create a box to zoom in or out. With mouse wheel clicked as a button slide the mouse up to zoom in, slide the mouse down to zooom out.

                If you know the designator, skip the explorer thing, zoom i to th edesired resolution and use the "S" hot command (i.e., s c1) .

                  is your mouse set up so that clicking the middle mouse button pans the screen to that point being center

                  and click hold draws a box that center zooms in/out to that point?

                   

                  are you using cross probing? this will make checking the layout so much nicer

                  if using DxD:

                  Tools-DxDesigber

                  will bring up a dialogue box to browse to schematic and turn on cross probing

                  Selection page of dialogue tells DxD & PADS how to react to selection (Pan/Zoom/Nothing to selection)

                   

                  a little different process for PowerLogic, but same basic idea

                   

                  the above will make your PADS experience much easier
