This is not much more work, but avoids trouble with unexpected trim results. So I divide the circle twice and delete the unneeded part. Usually, in a progressed drawing, there are already intersections where a circle should be trimmed. I avoid to trim circles when I'm not sure, from my experience, that it will work. It is regularly topic in the forum, but there was no solution so far which would not have created other issues or break current behavior. This is what happens in most videos above, first the CIRCLE becomes an ARC and on second trim one of the start/end angles is trimmed, when the other stays where it was trimmed on the CIRCLE.Īs said in the beginning, it is hard to estimate the users desire with one click. the Cutting Edge and then select the part of the object you want to trim.

When the first trim is applied by the rules of CIRCLE, following trims will be handled by ARC rules. So what happens when there is no visual reaction after trim, the CIRCLE was converted to an ARC, but with identical start/end angle. When a CIRCLE only needs center and radius to describe the geometry, an ARC has also a start and end angle. Generally, when a CIRCLE is trimmed, it becomes an ARC. For CAD these entities are different in their definition and handling. Video Lecture LibreCAD: Become an Expert - Design Softwares - Design Softwares full syllabus preparation. Most important, as I have seen in most videos above, is to understand the difference between CIRCLE and ARC entities.
