# CAD All CAD objects are imported and converted into Tessellated objects. Since their surfaces are currently converted to triangles - do not expect them to exhibit fully representative optical qualities, unless the object imported has flat segments for where the clear aperture on the part is. These are designed both for visual purposes, as well as for usage in optical systems. --- # 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.kostacloud.com/kostacloud/3d-geometric-elements/cad.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.
