detele by rectangle

community.cadence.com/.../scalpel-skill-file

thank u for ur response.

unfortunately the skill code does not work,

this code deletes clines located outside of the selection area and does not delete clines located inside of the selection area.

it looks like any clines which are not vertical and horizontal are ignored on this code and any clines on the selected area are deleted by segment.

thank u for ur response,

i do know how to use the delete by rectangle command but the poligon selection does not work.

what i would like to know is how to get his below.

you should be able to write a SKILL around SCALPEL that does the job. SCALPEL cuts the traces at intersect while the vertexes against the closed loop will give you the information of the clines located inside the loop.

thank u for ur  response.

unfortunately as i wrote above, the scalpel code does not work.

this skill code deletes clines located outside of the selected area and does not delete some clines located inside of the selected area.

and unfortuantely i do not know how to write a skill code.

Hi Masa,

The Scalpel routine works like drawing a thick or thin line through the traces. Basically similar to a blade cutting something.

If you run the command scalpel followed by a number, the number will be the width of the cut.

For a 100 mil cut  try scalpel 100

This will delete the trace segments by 100 mils wherever your cut line was placed. I don't know of any routine that works like drawing a polyagon.

There is also another method that is faster for cutting clines, You could take your board into "Specctra" and use the cut and delete segment options to basically create any cut type you want really fast. In specctra you draw the first cut line then the next cut line which cuts the traces. You then delete the traces between the cuts.

Best regards.

thank u for ur explanation, excellon1.

i can use this scalpel code with an offset value.

although i would like to use scalpel 0 and the zero offset value gives me an error, i can work around.

Sure thing Masa, glad to help you out.

The thing on having an offset of 0 is that when the clines got cut I reckon one would not see any cut. BTW the default value is 12mil as far as I can recall.

All the best.
