How to assign package height for all the components on the PCB layout board at a time or quickly

Take a look at this:- Height Definition in PCB Editor

Hai Steve,

The document only shows for defining the package height for one component at a time, is there a possiblity to define the package heights for mutlple components at time or like a table where we can list of all the component package height and define simultaneously.

Hai Steve,

One doubt, what is the property that needs to be added in the editable table, such that the package height is reflected in the PCB Layout.

It is explained in the app note but the key is you can call it anything you just need to ensure that the allegro.cfg has the line property_name=HEIGHT and that the footprints do not have a package height max defined in the dra file. 

Hai Steve,

I have tried to steps you have suggested but the package height in the 3D Canvas remains the same.

I think I am missing some steps here which I am doing.

Below is the things I have done.

In the Capture schematic, I have wen to edit properties and added two properties i.e Min Height and Max Height (Below image for reference)

It is reflected in the Edit Object Properties in the schematic design (Below image for reference)

I have added the property_name=HEIGHT in the allegro.cfg. (Below image for reference)

And I Have synced the schematic design file to the PCB layout file by the Update Layout Option in the Capture.

But after syncing with the PCB layout and when I View the 3D canvas window all the package heights are unchanged and same.

You've taken my post too literally...... the property_name=HEIGHT just means whatever property name you want to use. You only need one value so instead of calling the property Min Height or Max Height just use Max_Height then in the allegro.cfg edit the line so it says Max_Height=HEIGHT. You also need to ensure that the PCB Footprints DO NOT have a package height max defined. It MUST be empty.

Hi Rohit.

In relation to your question and as Steve has illustrated it is certainly possible  to set the property height via the schematic and then convey this info to the PCB Symbol. The best method and more time saving way of doing this is to change the PCB Symbol directly.

The advantage here is it will also allow for a quick review of that PCB Footprint and when complete you wont have to edit it again.

More than likely your design will use similar things such as resistors caps etc that would have the same package type and size.
There could well be 100's of these. If you resort to using the spreadsheet in the schematic editor to update the height property it will take time to do this. It is also error pron.

Beyond the Courtyard of the PCB Symbol which is used for placement, Package Geometry > Place_Bound_Top, there is also a feature
called DFA within allegro. "Design For assembly" The part of the pcb symbol that drives this is Package Geometry > DFA_Bound_Top.

Within the DFA feature of Allegro you can set up groups such as caps, resistors etc and have a spacing rule associated with these type of parts. In allegro when placing the footprints that are DFA enabled you will also get a visual cue that will indicate if a part is too close to another part which is very handy.

It can take time to get ones PCB Footprints correct, however once complete you wont have to go back and edit them. I think it would be a very good move to make sure all your PCB Footprints are Ok in advance since this in essence is what is actually driving your board.

Best Regards.
