Librecad trim circle1/31/2024 When I started with a "Snap" on the left-hand intersection of the circle and one vertical line, the circle became unclickable. I want to remove the portion of the circle lying between the two vertical lines. Here's the situation: Imagine the cross section of a balloon resting on two pins. So far, the "Divide" procedure evades me. I've tried "Snap at Intersection" but that hasn't gotten me anywhere. Part of the problem is that after apparently successfully trimming unwanted line and arc segments from my nearly completed drawing, there are several gaps between arc segments and the ends of the bounding parallel lines (at the ends of a slot with semi-circular ends) and also between fillet arcs and the boundaries of the slotted portion of the object. "Trim Two" again ignores the selection of the second bounding entry.Ģ. The bounding lines of the object were created with the "Draw Rectangle" command, and the same problem surfaces there - The bottom half of the rectangle disappears, leaving nothing on which to click during the second step. That leaves the unwanted line segment at the other end of the kerf. The only workaround I can imagine is to remove the circle and replace it with two semi-circles, so applying "Trim" can't obliterate the bottom half in Step 1 and the top half in Step 2. "Trim Two" lets me select one of the bounding lines, but not the other one, necessarily parallel to the first. "Trim" cuts away the short unwanted arc from the circle, but also cuts away the bottom of the circle as well. Here's a circle cut with a narrow horizontal kerf (i.e., a saw cut) from the outside of the piece, leaving a short unwanted arc of the circle as well as a short unwanted piece of the bounding line. Two problems have surfaced after chopping off the unwanted stuff:ġ. These two Trim options seem to be doing the opposite of what I intend, as already suggested in other places in this excellent forum. When I tried Trim on the bottom arc of the circle, the exact same result occurred, with only the sliver of the bottom of the circle remaining. When I tried Trim Two on the arc within the arm, alas, the lines of the arm and the flat bottom of the circle were extended to intersect with each other. I tried my trim selections in the opposite order, but got no effect at all. I almost did it with the upper arc of the circle, but when I used the trim command and first selected the line defining the top of the soon-to-be-truncated circle, when I next clicked on the unwanted part, the whole bottom of the circle was removed, i.e., the exact opposite of what I intended. Once those four intersections are pinned down, I'll need to delete the three unwanted segments of the circle: top, bottom and inside the arm. The circle has not quite complete lines across the top and bottom that I haven't been able to force to snap to the arc of the circle, except at two points where the arm intersects the circle. The circle and its arm are there, and the arm even has a 180 degree rounded end. My project now involves a bracket made from quarter inch thick plate that consists of a circle flattened on top and bottom and having a narrow arm extending up and to the right at about 45 degrees. Progressing to the second drawing of my new career as a LibreCAD draftsperson.
