Shape parameters - thermal/anti - pos layer

stump1019

When editing Dynamic Shape Instance Parameters what are the factors that come into play with regard to controlling the copper web between pins if you make your Thru pin, SMD pin and Via settings to Thermal/anti ? This is on a positive layer shape.

    Unless I'm misunderstanding your question here are several things that you want to pay attention to when you use thermal relief.  You can set these globally or independently per shape.

    Globally...

     Setup>Design Parameters, Shapes Tab, Edit global dynamic shape parameters..., Thermal relief connects Tab

    1] Orthogonal or Diagonal contact. 2] Minimun (maybe 2) and Maximum (maybe 4) connects.

    3] Use a fixed thermal width, 4] Use thermal width oversize

     

    Clearances Tab 

    5] You can have the dynamic shape follow either the Thermal/anti that was defined when the padstack was made or follow your DRCs in Constraint Manager. 6] You can oversize the clearance.  

    Independently...

    Shape>Select Shape or Void, Select the shape and RMB (right mouse button), Select Parameters... Change settings as desired.
