Many of you already received communications about the move of the Cadence user community into cadence.com. And many of you have already joined, with over 4000 registrations in the first two weeks.

The new Cadence Community enhances the ability of Cadence users to connect and collaborate. In addition to moving the community into cadence.com -- enabling single sign-on for community, Sourcelink and Cadence events -- the new site is organized around nine technology segments, giving you easy access to product information, training, forums and blogs. Some of the new features include:
  • Ability to respond to posts via e-mail
  • Technology-specific blogs
  • Latest Web 2.0 social networking capabilities
  • Public profile options
  • Private messaging
  • Friends lists
Visit the new Cadence Community today at www.cadence.com/community and join the discussions!

Registration note: Due to the scope of the enhancements and the new SSO registration system, we were not able to migrate existing cdnusers.org member accounts. So new registrations are required, but this enables a broader set of functionality we think you'll enjoy.

Forum note: Under the guidance of forum moderators, we have taken the 20+ cdnusers.org forums and consolidated them into 11 forums on the new site. Posts have been brought over so you can leverage that posting history. CDNusers forums will be set to read only starting 7/30, and cdnusers.org will be redirected to the new community on 8/4.

Hi,

I wonder if there is already a method in place to create
multiple rows (list for the ?subRect argument of  rodCreatePath)
of subrectagles, depending on the width of the master path?

I didn't want to invent the wheel twice.

Cheers Bernd

Bernd,

There's a PCR asking for this, but for now you have to create the multiple rows yourself.

Regards,

Andrew.

Andrew,

I knew about the PCR, but I thought someone out there
could already have a solution for this, but it seems not.

I'm close to be ready with my solution for it, if it's done
I'll attach the code to this thread.

Cheers Bernd

;; Function(s) : BFcreateSubRectList
;;
;; Author : Bernd Fischer
;;
;; Date : Tue. 4. June 2006

;; Version : 1.0
;;
;; Application : Virtuoso/Virtuoso XL
;;
;; SW Release : 5.1.41 and higher

;; SKILL Lint : PASSed
;;
;; Global Variable(s) : None

;; Description : This function creates a list or lists of subrectangle
;; arguments for the 'rodCreatePath' function.
;; It gives the rodCreatePath function the ability to create
;; multiple rows of subrectangels depending on the with of
;; the master path.
;; It can be called directly as value for l_subRect of
;; rodCreatePath or used in context with a variable which
;; holds the l_subRect value.
;;
;; Arguments : txl_layer Text string, integer, or list
;; specifying the layer or layer
;; purpose pair for the sub
;; rectangles.
;; n_masterPathWidth Positive integer or floating
;; point number specifying the
;; width of the master path.
;; n_subRectWidth Positive integer or floating
;; point number specifying the
;; width of the sub rectangles.
;; n_subRectSpace Positive integer or floating
;; point number specifying the
;; spacing between the sub
;; rectangles.
;; n_beginOffset Signed integer or floating
;; point number specifying the
;; offset of the edge of the first
;; subrectangle from the starting
;; edge of the master path.
;; n_endOffset Signed integer or floating
;; point number specifying the
;; offset of the edge of the first
;; subrectangle from the starting
;; edge of the master path.
;; n_sideOffset Signed integer or floating
;; point number specifying the
;; offset along the edges of the
;; master path to edges of the
;; most right and left subrectangle
;; row.
;;
;; Return Value : l_subRectList
;;
;; Example : rodCreatePath(
;; ...
;; ?subRect BFcreateSubRectList(...)
;; )
;; or
;; l_subRect = BFcreateSubRectList(...)
;; rodCreatePath(
;; ...
;; ?subRect l_subRect
;; )
;; Modification : None

It seems that somehow the formatting get lost while posting code, worse option?
Some idea why?

Bernd
