If you are using Dxdesigner you can do this with dock/undock (https://supportnet.mentor.com/portal?do=reference.appnote&id=MG576006)

Re: How to separate PCB out of project?
Hi,
You can close your active design then try copy.
Can you explain in detail what you want to do?

Server setup of Valor Tool
Hello ,
we have a plan to change our current DFM server to one of the new Virtual Server .Please confirm whether the server installation files will be worked in the new proposed virtual server .
Also would like to know the Valor vSure will be worked on Windows 8.1 /Windows 10 Operationg system
Thanks and Regards

Need help in identifying nets that are being forward annotate
I need to set the default value of the required test point property to '1'.
I was hoping to use the event onforwardannotate to do so, but unfortunately I can't find an object that holds the changes that should be forward to the pcb.
I'm trying to get the same information I can get from the pendingfachange.text report.
I would appreciate any help.

Change implicit power supply definitions on schematic level
I downloaded the ODA starter library to begin playing around with xDX Designer in PADS VX.0 and noticed that most ICs consisting of multiple gates define the power supply and ground pins implicitly (e.g., a dual op-amp package like the LM393AN has the supply voltages defined as "V+" on pin 8 and "V-" on pin 4, or on a 74xx quad logic gate, Vcc and GND on their respective pins.) See below, for example:
The bottom two properties designate pin 4 and 8 as the negative and positive supply voltages, respectively. However, if I change the property value to match the name of my net for one of the nets (e.g., if I change "V-;4" to "-10V,4") then the property field for the other signal pin disappears. I am then unable to add another "Signal" property field as that is not one of the options that pops up when adding a new field. See below:
This leads me to believe that this is either a bug with the part library and/or DXDesigner, or that this is not the proper way to change the signal pin definition (and I am leaning towards the latter.) It may be that it is simply not best-practice in circuit design to have circuits that have different supply voltages for op-amps or other ICs, however this is the case for several of our legacy designs where we have some op-amps getting +/-15V and others getting +/-10V for example, and the particular design and components necessitate it.
Without editing the library part, is there a way to manually select the net that the signal pins connect to for individual symbols in a schematic/block? (See above for example, where one instance of an op-amp must have V+ and V- mapped to +/- 10V respectively, and the other to +/- 15V)

Exporting of Silkscreen decals, board outlines etc. as a drafting object
I am currently designing a set of PCBs that are meant to connect to each other in a stack. At the moment, I am manually tracing key features of the boards with drafting lines to create a "pattern" that I can use to compare placements etc. of components on other PCBs in the stack. The tracing is a bit tedious however. Is there are way to select silkscreen decals and board outlines and export them as a "Drafting" object that I can import into other designs?
I am using Pads Layout VX.0

Re: Change implicit power supply definitions on schematic level
It's a bug, in the property definition file Signal is set as a single entry you need to change this to multiple. Open the Central Library from the toolbar and in there open the Property Definition Editor. Find Signal and expand the dialog by pressing the Advanced button and modify the Instances Allowed from Single to Multiple.
Close the Library tools and run Tools - Update Libraries to refresh the property list. You should then be able to modify both strings without them disappearing.
If the Tools - Update Libraries doesn't work just close and re-open xDX Designer.

Re: Change implicit power supply definitions on schematic level
To add to your general comments, you can create parts with the power pins defined explicitly on the symbol and you connect up to them with the required nets. These can be created in a number of ways, one is known as a Hetero Type 2 where one symbol shows the power pins and another doesn't. Or you could simply show the power on all symbols and connect them to the correct supply. To group them together use the PKG_GRP property with the same value (any alphanumeric).
An example of the hetero 2 is shown in the picture (also look it up in the on-line help and/or SupportNet).

Re: Change implicit power supply definitions on schematic level
If you use simulation, the easiest method to apply a model is to show the power pins on all fractures and connect them to the correct supply.

Re: Exporting of Silkscreen decals, board outlines etc. as a drafting object
Kirk,
Have you had a chance to look at PADS Professional or Xpedition? The new 3D capabilities within these tools will allow you to work directly in 3D and import/export full PCB layouts in STEP format and then do full visual, dynamic, and batch 3D DRC checking to the component placements within one board or from board to board.
Take a look here for more information:
PADS Professional Layout - Mentor Graphics
or
3D Layout PCB Design solution - Mentor Graphics
Good Luck,

Re: Dimensions in cell editor
Just saw Vern's comment - if you just need measurements (not dimensions) that will certainly work. Just make sure to switch into 'Edge Mode' rather than 'Center Mode' for the measurement.

Re: Dimensions in cell editor
Hi Pradeep,
Unfortunately, you cannot dimension directly to a pad edge. This is a request on Mentor Ideas (Idea D8038) that I encourage you to vote on.
As a workaround, you can create a rectangle the same size as the pads on a User Layer and dimension from edge-to-edge on those instead. This should let you put in all the dimensions you need. You may find RMB > Snap > Toggle Hover Snap useful in creating the rectangles the same size as the pad. In the picture below, I created some pink rectangles on a User Layer and was able to dimension between them.

Re: Change implicit power supply definitions on schematic level
Thanks for all the helpful responses. Changing the Instances Allowed to multiple let me view and modify all of the signal values within the schematic, and I was able to use Hetero Type 2 symbols to show those pins. The other workaround I found is to use the Supply Rename property to manually reassign supply pins to the proper nets (e.g., Supply Rename = V+=+10V V-=-10V where I've already made nets named +10V and -10V)

Re: Tech Notes
Ritu - thanks for your question. If you have an active support contract with Mentor, you can access the TechNote on SupportNet. Your communities credentials should be the same as your SupportNet credentials (assuming you have an active support contract). SupportNet link: mentor.com/support.
