# PO\_Check2DOrtho Analysis 2D plans (curves) and visualize non-orthogonal geometries based on a reference plane. ## Options * **Custom Plane** Set a custom plane by two points (X axis). Default is a World XY plane. * **Angle Tolerance** A degree number from 0 to 360 used for non-orthogonal checks. A perfect orthogonal geometry means 90 degree from a base axis when angle tolerance is set to 0. Increase the angle tolerance would consider lines orthogonal within a range of 90 +- the angle tolerance. Default 0.01. Notes: * The results are non-orthogonal lines. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.pollination.solutions/user-manual/rhino-plugin/pollination-commands/alphabetically/po_check2dortho.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
