Etch spacing

justintesmer

Ok so, I'm trying to make a quick and dirty board without a netlist because it consist of only cantact pads and solder pads.  However, i have two pads that need to connect, then connect to a via and I cannot get OrCAD to stop displacing the copper on one of the padswhen using route->connect.  I triedunchecking the "replace etch" check box in the options, i tried using lines of top copper rather than a route, i triedusing the "defer dynamic copper" option, but nothing has worked so far.  the bottom of the board has single pads that connect to the vias no problem, but for some reason i canot connect two pads together, both defined as top copped on a dummy net.  any ideas?

thanks,

-justin

     sorry, that probably would have been helpful.  here is a new file with a trace cutting through one of the pads.

     again, i am trying to connect both pads to eachother, then to the via.  i try your change shap type suggestion, but its seems to only be able to convert static to dynamic, not the other way around.if i just use shape select and go to the options tab, the dropdown box is set to dynamic copper and greyed out.  anyother ideas?

    thank you again,

     Ok Justin, I think this is what you want. I am attaching a zip with screen shots and the final board.

    1) Click on the "Shape Select" icon (or Shape->Select Shape from the menu)

    2) Click on shape; right mouse; select "change shape type".  You will see in the command window that it changed from dynamic to static.  Ignore the grayed out option in the option tab for now.  (you can go back and forth using this method)

     

    3) Select "Add Connect" from the icons, change your option to "Snap to connect point", shove on (or hug), and then just draw the line back over to the pad.

    4) To add the pad-to-pad connections click on the shape and draw them over.

    You can keep adding via to pad connections as you desire using this method.  Not sure how many you wanted...

     

    Check it out and ask if you have more questions.

     Fantastic.  Thank you that worked perfectly.  I'm not sure why selecting the shape and going to Shape->change shape type didn't work, but right click->change shape type does.  Ah the quirks of OrCAD.  Thank you again,

     You may be doing the operation out of order because it works just fine either way on my system.

    0) All items deselected!!!

    1) (from menu) Shape->Change shape type

    2) From options tab: Shape Fill->To static solid

    3) Click on shape

    4) Done

    Should have converted it!

    Glad it's working for you.
