Deleting Keepouts

Hi!

Can you explain more details your purpose ?  axlDeleteObject(o_dbid/lo_dbid [g_mode])  can do that.

Hi luan,

Actually why because I wrote the code ROUTE KEEPOUT creates automatically through the net name of via by input file in that before they create if Keepout already exist means they need do delete and then want to create.

Deletion of ROUTE KEEPOUT must be belong to INFILE'S present via netname.

I will attach my code and sample in file.

Please guide me to how to do it.

I would personally add a property to the keepout shape. Simply a comment 'string' would do. Then before you create a shape, delete all previously shapes with the comment=<your string>.

So when creating shapes attach a comment to it:

shape=axlDBCreateShape(path t c)

axlDBAddProp(car(shape) list('COMMENT "custom_keepout"))

Then somewhere at the begin of the function run this to remove all shapes:

foreach(shp setof(item axlDBGetShapes("ROUTE KEEPOUT")         item->prop->COMMENT=="custom_keepout"))
axlDBRefreshId(nil)

Also put a close(in1) just after the while(gets(  statement to close the fileport.

Last addition, if you create RKO shapes then after each RKO you create in a etch shape Allegro will automatically void it. This takes a lot of time.

If you use the axlDBCloak() function to call your create function then the shape update is only done after your function returns.

So like this: axlDBCloak('backdrillkeep()     '(shape ignoreFixed))

Thanks for your reply while deleting property it comes argument error. Could you please update in my code.

and also the  axlDBCloak('backdrillkeep()     '(shape ignoreFixed)) these condition.

Oeps.. change those lines to : 

axlDeleteObject(setof(item axlDBGetShapes("ROUTE KEEPOUT") item->prop->COMMENT=="custom_keepout"))

axlDBRefreshId(nil)

Instead calling the function directly by 'backdrillkeep()' call it through a axlDBCloak():

axlDBCloak('backdrillkeep()     '(shape ignoreFixed))

Thanks a lot

Thanks a lot
