I need to create a regular 5/2 star in Sketch. Like this:
I tried it, but Sketch can't draw simple geometry, it has a strange snapping.
You can see it in this video on youtube: https://youtu.be/HPVo685hyxU
Unfortunately Sketch doesn't snap to vector points, otherwise this would be easy. However, we can snap to the bounding box of an object and it is possible to abuse this to create a perfect star.
Create a five sided polygon and remove the vector points one by one and create vertical and horizontal guidelines for each point. Then use these guidelines to snap the cursor when drawing a star:
Star is available in Insert > Shape > Star
Draw the star you can add the type of color you want and if you double click on it and you can change it from it's nodes. A simple vector work.
Draw the star like you did in the video:
The Double click on it. It'll show you the nodes. Align then make anything from this star as you like: **You can add/delete nodes too: UPDATE
I am able to do that just by adjusting nodes.
