I'm reading a manga in which often 起こす is used with に, in situations like this:
The characters just finished making a test piece for a shirt, and the speaker is saying to the other characters that sentence; I kinda understand it ("Next we have to copy this [shirt] on a pattern / to make a pattern out of this shirt"), but I'm wondering about the form に起こす.
I tried looking on Jisho, and the third meaning (To create, to produce) kinda seems to fit, but I tried looking in the examples and no one uses に, instead they use を. Then I tried Weblio, which again always uses を, with the sole exception of a single example of meaning 8 (速記や録音の音声などを文字化する。また、文章を書いたり文書を作ったりする。「講演の録音を原稿に—・す」); this is specific for transcribing audio or shorthand, though, so I'm not sure this is the meaning in which it's used in the sentence above (and や seems to point to a non exaustive list, so they could just be examples).
My guess is that the meaning 8 applies, maybe as an extension, but with the underlying idea of copying/transcribing/putting something onto something else, so こいつをパターンに起こす would mean something like "Copy it in a pattern", or (I think in a more natural English) "Make a pattern out of this", the basic idea being to look at the shirt they made and use it to make a copy on paper to be used as pattern.
Am I on the right track?
