Polygon pour priority

rjcurtis

In Eagle when I had overlapping Polygons I could assign a priority, so there would be a precedence in them.  It seems in Altium there is this too, but I cannot find it in Circuit Studio?

 

Basically I'd like to create a pour covering an whole layer, then have several smaller pours within that layer for specific things.  I can't use a split plane as there are also some tracks on the layer.

 

It seems this is a pretty basic requirement yet it doesn't seem to be in there as far as I can tell.

    Hi Jeremy,

     

    Sorry for the delayed response!

     

    Here is your answer from the devs:

     

    Currently CircuitStudio doesn't expose the pour order even though it is stored in the PCB file.

     

    The larger outer polygons need to be created last because newer polygons are poured last in the pouring order.

     

    To fix the board you will need to re-create the large outer polygon so that it pours after the others.

     

    Open the PCB panel and choose Polygons from the drop down list.

    Click <All Polygons> and then double click on the large polygon in the list of polygons names, e.g. TOP_GND

    Write down the settings (or take screen capture), e.g.

     

    Remove islands: 2 sq mm

    Arc approx: 0.013mm

    Necks: 0.127mm

    Name: TOP_1V2_C_1

    TopLayer

    Net: 1V2_C

    Pour over all same net objects

    remove dead copper

     

    Click the Outline Vertices tab at the top and click the Menu button > Export to CSV, name it, e.g. TOP_1V2_C_1

    Cancel out of the dialog and click on the document tab to take the focus back to the PCB document

    Press Delete to delete the polygon

     

    Press the Home > Polygon button, change the Name e.g. TOP_1V2_C_1 and draw a small simple polygon anywhere on the board

     

    Double click e.g. TOP_1V2_C_1 in the panel and ensure the correct Net is specified in teh Connect to Net setting.

    Click the Outline Vertices tab

    Menu > Import From CSV and double click on the CSV file e.g. TOP_1V2_C_1.csv

    Click back to the Graphical tab

    Ensure Is Poured is ticked and click OK

    Click Repour Now

     

    The Home > Polygon Pour > Repour All button should now repour the inner polygons before the new one you just created.

    I am already lost and will attempt no such convoluted method. Once again CS lets users down, sold as professional software works like the great AD but in fact as a software it looks like a buggy hobby project........ I take it that the next update will deal with this ? it's kind of essential and basic even of software that costs 1/4 the price.

    Just try using the Send To Back, Bring To Front options to reorder the polygons as mentioned in my earlier post (below).

    OK thank you will give it a go.
