Hi,

I need to draw a floor drain, so I drew a 6" diameter circle. I then drew the X and Y axis lines (I have Quadrant snap set), and I offset these 3/4" in each direction. I then used Free Trim to get rid of the end segments. And it works about 2/3rds of the time, but the issues are:

It erases the entire line instead of just the shortest end overlaps.
It leaves a point at the intersection of the longer segments, where they crossed each other.

Can anyone confirm this?

I'm not seeing any of this, it's trimming as expected and no points left. What is your miss distance set to? We use 10 here. Could it be inferred snapping? Not using that here.

Miss Distance is set to 20, and I am still using the middle button to snap.

I have used Free Trim quite often, and this is the first time I have had this sort of problem. I will try it in a new drawing.

Edit: I just tried it in a new drawing, and the same things occurred. I use a keyboard shortcut to get to the Free Trim menu, and I select it by Area. After hitting Begin, I just select the segments to erase with the left button. No object snapping is involved.

So I can duplicate this if I snap towards the end of the line near the circle. If I just lift click to pick anywhere including near the same point that snapping causes the issue it still works correctly. Are you sure inferred snapping is not enabled in the program prefs?

I double checked - Inference Snapping is not enabled.

No. Is this an overshoot problem?

I'm using using DCad to design circuit boards, i.e. tight scale like you, and use freetrim a lot. I recall stumbling with overshoot.

No. No overshoots here.

I am not using overshoots.

(New to the Forum.)
I tried this free trim issue, making drain circle etc. When I click on one end of the line that I want trimmed, that little tip does erase. But when I trim the other end, on the other side of the circle, the long line disappears and a little dot is left. It's almost like free trim is working on the line as if it's dashed not solid. So it's registering my click in the wrong place? or a rounding error?

1. Draw a rectangle 7 1/2" square with ctr pt on
2. snap to ctr pt and draw circle with a 3" radius

no offsetting or cleanup involved. though the rectangle may be more of a challenge if you use dir/dist input.

Hi Dan,

That is different from the drain that I was drawing:

I avoid that problem by using the net hatch to create the grid in the circle, fewer entities. Put on it's own layer in a symbol, and you can even not show it at small scales by setting the layers max/min scales.

Roger, that's a good point.

But, we should not be having free trim issues.
