• Synonym原案げんあんNeutralThe original proposal that serves as the basis, as in 「政府原案」; 素案 is a still earlier, rougher idea that precedes it.
• Related原稿げんこうNeutralA written text or manuscript, e.g. a speech script or a piece submitted for publication; it refers to the text itself, not specifically to a plan as 素案 does.
• Related稿こうWrittenWritten/formal word for a manuscript or version, often in compounds like 「第二稿」 or 「稿を改める」.
• Related草稿そうこうNeutralAn unfinished draft of a piece of writing; the focus is on the text itself, while 素案 centers on a plan or scheme.
• Related下書きしたがきNeutralRough copy made before the fair version, also an underdrawing in art; colloquial and very common in speech.
• Related文案ぶんあんWrittenWritten/formal term for a draft of a document, seen in official papers and advertising copy.
• Related案文あんぶんWrittenA prepared draft document, as in 「条約の案文」; leans toward official-document wording.

「素案」 is the rough idea before a formal proposal takes shape; 「原案」 is the base proposal, 「草案」 a document's first draft. For drafts of writing use 「下書き」 or 「草稿」; 「原稿」 is a manuscript or script, not a plan; 「稿」「文案」「案文」 are written terms.
