Elliptical holes in a circular plate

SP_8016115 — Tue, 03 Oct 2023 13:28:28 GMT

I want to build a model of a circular plate with elliptical holes in it. The holes center coordinate and orientation data are in a .txt file. The center coordinates and orientation are random. Can I make this type of tabulated pattern in creo, please if possible help me out

Circular plate radius is - 1024 mm

Ellipse semi major - 30 mm

Ellipse semi minor - 15 mm

I have attached the .txt file . first and second column is x and y coordinate and third column is orientation of major axis from x

This should be possible using sketch patterns. Creo supports sketcher csys inside a sketch that can be patterned. The center locations can be imported using an point offset csys feature.

Offset datum point using import option

You can then create a pattern for the csys orientation (clocking) at each center location. See below.

Refer to this thread for reference:

Here is a simple example of clocking the csys inside a sketch and patterning it. The part is posted for reference.
