Dynamic Shape loses connectivity after stretch

Leron

Dear All,

I have a shape made of dynamic copper on TOP. There is a net assigned to it (RL), as you can see

When I stretch it it loses the connectivity, becomes unfilled

and gives error in status:

Dynamic shapes out of date: 1 out of 15

Current fill mode : SMOOTH

<<< ETCH >>>

Layer = TOP

State: No Etch Point on shape: (-1.808 1.376) Net: RL

How to solve this?

Thanks

Francesco

    Hi,

    The "Suppress shapes less than" option under Global Dynamic Shape Parameters does control when a dynamic shape is suppressed on the canvas, it is not a setting for artwork output.  Seeing that you set the value to 0 and the shape still does not have show its fill maybe one of the following conditions is causing it to be unfilled.:

    1.  A Route Keepout is defined in the area where you have drawn the dynamic shape.
    2.  The Shape is totally inside of a Constraint Region which has larger than expected clearances so it is just voided away.

    Type moving the unfilled dynamic shape to another area of the board to see if it fills again.

    Hope this helps,
    Mike Catrambone

    Francesco to echo what Mike said, my thinking is that a constraint is set too high. Take a look at your "Shape to SMD Pin" clearance as a starting point, verify your other shape to clearance values meet your design goals.

    Here is a picture of what it looks like when a shape is connected to a smd pin but the shape to smd pin value is too high. In this case 100mIL.

    Other things to check would be the "Pin Properties" of your symbol to make sure nothing is set at the pin level that could clear a shape..

    Are you getting any DRC errors ?

    All the best

    Paul.

    Hi Paul, Hi Mike,

    I tried again so set the "Suppress shapes less than" to 0. With older version of Allegro it did not solve the issue but with the latest it seems to do the job.

    Thanks a lot for your hints and support.
