'Absehen' is a separable verb. The prefix 'ab-' goes at the end in a main clause. In subordinate clauses and in the infinitive with 'zu', the verb stays together.

I decide not to file a complaint.
The meaning of 'absehen' is recognizable from the sentence structure: 'absehen von' means to ignore or disregard, 'es auf etwas absehen' means to target or be after something, and without a complement it means to foresee or to copy.
Sehen wir von diesem kleinen Fehler ab.
Let’s overlook this small mistake.
In the meaning of 'ignorieren' (to ignore) or 'verzichten' (to refrain from), 'absehen' is always used with the preposition 'von' and the dative. The construction is: 'von etwas absehen' (to refrain from/disregard something).
Die Polizei sah von einer Strafe ab.
The police decided not to impose a penalty.
The expression 'es auf jemanden/etwas absehen' (to be after someone/something) is fixed. The 'es' is an obligatory part of the construction, and the target of the intention is in the accusative.

The mosquito is apparently after me.
In the meaning of 'voraussehen' (to foresee), 'absehen' is often used with modal verbs (especially 'können') or in the passive-like form 'ist abzusehen' (can be foreseen/is foreseeable). It usually refers to abstract things like consequences or developments.
Man kann noch nicht absehen, wie sich die Situation entwickeln wird.
It is not yet possible to foresee how the situation will develop.
This meaning is strongly associated with the context of exams or school. You can 'bei jemandem' (from someone) or 'von etwas' (from something, e.g., a note) 'absehen' (copy).
Er hat versucht, bei seiner Nachbarin abzusehen.
He tried to copy from the girl sitting next to him.
to give up / to do without
Both words describe a deliberate decision not to do something or not to claim something. „Von etwas absehen“ tends to emphasize dropping a planned measure or making an exception, while „verzichten auf“ emphasizes voluntarily giving up a possible benefit or claim.
