Should I use "such that," "so that," or "in a way that"? [duplicate]

If you are talking about doing something or asking others to do a thing a certain way, the adverb SO should be used;

'Position the frame on the cone using the sliding bar so that the cursor of the meter is on the crosshairs'

SUCH is a determiner used mainly to add optional emphasis to a noun or noun phrase;
'she has pretty eyes', 'she has such pretty eyes'

(Both words have many more meanings and uses which can be studied at leisure) http://dictionary.cambridge.org/grammar/british-grammar/such

You can ofcourse, use SUCH in your instructions if you really want to;

'Position the lens in such a way so that the lower segment marking is on the measuring dial.'

A very basic rule-of-thumb is, 'SO do something' and 'SUCH emphasis'
