Measure the dimensions and radii from the technical drawing.

Technical Drawing Analysis:

The drawing displays various dimensions and radii related to a component. The primary dimensions indicated are:

• Overall width: 822±1
• Overall height: 622±1

Additionally, specific radii are noted:

• A radius of R2⁺³, specified as '8 радиусов' (8 radii), is indicated in the top-left corner, suggesting a specific fillet or rounding detail.
• In the cross-section view (A-A, 1:1), two radii of R6* are shown, defining the shape of a groove or channel.
• The cross-section also shows a height dimension of 12⁺³_-2, possibly referring to the depth or width of the groove.
• A dimension of 18⁺¹_-2 is given, with the text 'по контуру' (along the contour), likely indicating a length or width measurement related to the groove or sealing area.
• There is a note: 'Место начало нанесения уплотнения' (Location of the start of seal application), indicating a specific functional area on the component.

Summary of dimensions:

Overall dimensions: 822±1 and 622±1.

Radii: R2⁺³ (8 radii), R6* (two instances).

Other dimensions: 12⁺³_-2, 18⁺¹_-2 (along contour).
