Negative artwork where autovoid ?! (allegro)

When the stackup layers are negative no autovoids are generated. On negative board builds the voids are generated at the artwork generation stage of the design process. The only way to obtain a true wysiwyg appearance to use positive artwork layers.

hm....thanks!

but in older versions it was possible...

Can you please clarify your statement:

"Allegro not create autovoid" when the layer is marked as NEGATIVE."

Here is some basic question / answers regarding negative planes which you may already know about but I wanted to outline them just in case you are a new user of the tool.

[i]Do you not see the void opening in the negative planes which represents the pin and via voids ? [/i]
If so there is a setting under the Display tab that controls the look of negative planes.

[i]Do you not see the pin and via void openings in your output gerber file ? [/i]
If so you have the Plot Mode defined as Positive vs Negative.

Negative Planes can be defined as true WYSIWYG by setting up Thermal Flash symbols that reference Flash Names in the Thermal Relief definition of the padstacks. This is not commonly used since Dynamic shapes were introduced but it is an option if you choose to use Negative Planes.

explaining: in older versions allegro, in stackup i mark power planes like NEGATIVE and make autovoid myself (there was that option for shapes) but in 15.2 etc NO option for shapes like "autovoid shape"... and i not see visually VOIDING ( not needed vias/pins) while plane maks as NEGANIVE not in DYNAMIC not in STATIC shape. but if plane POSITIVE - vias/pins in moment becomes with VOID do you understand? (sorry for my english...) PS If so there is a setting under the Display tab that controls the look of negative planes. - which setting??? where is it? Thermal Flash symbols - earlier i'm not used flash symbols...

Do you not see the void opening in the negative planes which represents the pin and via voids ? yes i'm not see void
