Hello.

I'm trying to create a label for a RFID card of mine and I'm trying to find the way I can achieve precision to rounding a rectangle's corners.

Let me quote wikipedia's article [1] on credit cards:

The size of most credit cards is 85.60 mm × 53.98 mm (3.370 in × 2.125 in) and rounded corners with a radius of 2.88–3.48 mm,[3] conforming to the ISO/IEC 7810 ID-1 standard, the same size as ATM cards and other payment cards, such as debit cards.

So, I create a rectangle with the given size and then I select the Node Tool.
When I click on a rounding radius handle I'm only able to drag the handle and not input a precise (horizontal and/or vertical) rounding radius.

How do I achieve the desired precision on rounding?

With the active there are fields in the tool control bar labelled Rx and Ry which are used to set the X and Y radius for the corners. You'll need to set them both to the same value to get a quarter-circle corner for a credit card design - if they're different you'll get a quarter-ellipse instead.

Truly spoken.
Also, as phiscribe hinted on IRC, you can double-click the rectangle and get to change that property.

Thank you.
