If the component mfr. does not provide a tolerance, you need to add a nominal tolerance of +/- 0.15 mm

Every dimension has a tolerance. Never put the Nominal dimension in the Min/Max cells.

Hi Tom,

D does not have a min or max or tolerance, in this case do I put 6mm on both min and max?
Also does the courtyard will be enough for the max component lenght of 7.1mm which IMHO should not be centered?

Use these dimensions: 
D = body Length
W - Body Width
A = Terminal Width
H = Height

Do not use the L or J dimensions.

The NIB sticks up in the air and solder goes under it.

Use the Polarized Capacitor component family.

Hi Tom,

I'm a bit confused when I look at the table from Vishay;
http://www.vishay.com/docs/40006/594d.pdf

I try to build one having the case C but some value given are either max or ref. 

Also does dimension J is important in this case?

We'll be releasing a new document this week that clearly defines every component family with 3D model pictures, land patterns, pin assignments, silkscreen, zero component orientation, recommended pad shape, component lead terminals superimposed with pad (graphic on a mechanical layer) in the CAD footprint and solder joint goal tables for each lead style.

Tom,

It actually is alittle confusing.

I actually had to spend some time getting the correctfootprint for these polar capacitors.

If the name could simply be changed topolarized capacitors, it might actually save some time for other people who’llbe having this issue in the future.

I’m not saying it’s an issue per se but itmight just make it easier for people to search for these pads.

I see it now.

I spoke too soon without actually looking at the viewer properly.

The choice is "Chip, Capacitor, Polarized"

I am not interested in a 3D model. I want to be able to calculate a landpattern from the viewer and there is no choice for that.

We have Capacitors with Nibs for a long time.

They are "Chip, Polarized Capacitors" and the 3D STEP model looks perfect from Library Expert.
