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Dynamic shapes out of date: 1 out of 15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

    Looks like your shape has just gone non dynamic. Try a Display - Status and click on Update to Smooth.

    Hi Steve,

    it does not work:

    and the report gives the info I posted in the first post.

    Leron, What version are you running ?, it looks like in your picture you have 2 shapes but they are not merged. One is horizontal covering the pins and one is vertical.  Perhaps try this. Merge both shapes then drag the one you want to encompass the pins or get rid of the vertical shape...

    Check your "Global Dynamic Shape Parameters" so the shapes auto update.

    Let us know if it works.

    Regards Paul.

    Hi Paul,

    thanks for your advises.. however I don't think they will solve the issue. 

    Let me answer to your questions:

    I am using Allegro PCB Designer 17.2-2016 S024. 

    The shapes cannot be merged since one is static and is part of spiral inductor made directly with the PCB while the other is dynamic copper.

    I think that the problem is related to some minimum area requirement to have a shape dynamic. As you can see in the picture below I have the same issue with two other pins of my BGA:

    Any further suggestion is very welcome.

    BTW, what is the difference in having a shape on ETCH/TOP or on Boundary/TOP

    Check the value you have set for Shape - Global Dynamic Params - Void Controls tab - suppress shapes less than, you might want to reduce this value and see if that helps. For the Boundary v Shape, boundary is what you draw (from a shape point of view), the shape is he resulting object. If you remove islands for example they will remain on the boundary layer (if that makes sense).
