Hi all, I am having trouble closing this path. On the left you can see it it made up of 2 lines. On the right I have deleted the top line and I am trying to recreated it using the line tool however the tool seems to force a curve, not a straight line.

If I start with a line not on the curves edge (somewhere else on the bed, then joint it too the curve’s edge (snaps to point), it does stay straight and I can go straight across to the other point and snap to that point, but the path is not close and the shape does not fill (as per shape on the left).

Any ideas?

Cheers
Guy

To create a straight line:

  1. select Line tool
  2. click once with the mouse on start point and release
  3. move mouse to desired end point
  4. click once and release
  5. repeat until done
  6. push ESC or right click to end Line

I found a work around by closing the path with the curve, selecting this node point and selecting L to convert it to a line, however I would still like to know if there is a way to do this with a direct line draw.

That doesn’t work in this case, it is exactly what I am doing, but it creates a curve, not a straight line.

5

It’s very likely not exactly what you’re doing. You would need to be dragging after the first click rather than releasing immediately.

6

Sorry, you are right, when I do it that way, this is what get created.

Please reread the steps and follow them exactly. At no point should you be dragging. First click should be at one of the end points. Second click should be at the other end point.

Yes, that is what I did
1: Click on the tip on the left and hold the mouse button down: Result: LB adds a vertical line extending above the point I selected, and a straight line out to the direction of mouse movement.
2: I move the mouse, holding the left mouse button down, over to the tip on the right until it becomes the little target symbol representing the snap to point. I release. Nothing happens other than the line does not snap to the point, it stays with the mouse movement and reverts to a curve.
3: I move the mouse over the point again in the same way, click again, and get the results seen in the last image.

Maybe there’s something about the design that I’m missing. Can you upload the .lbrn file here for review?

But note that I’m saying you should not be holding down the mouse button.

This is what PY is telling you NOT to do. Do not hold the mouse button down, click once and let go. Now, move the mouse to the next location, WITHOUT holding the button. When you arrive at the next point, click once to complete the line.

When you hold the mouse button, the result is a curved line segment, which you don’t want.

Sure,

I have a little video recording but I can’t upload that here unfortunately.

12

I have tried BOTH, holding the mouse button down, and NOT holding the mouse button down. NEITHER work.

13

I did say it was exactly what I was doing but I was told I was not doing it, so I swapped.

14

There is indeed something odd going on with the file.

How was the shape created?

Clicking on one of the end points seems to extend the line instead of creating a new line segment.

@Rick Could this be related to the changes in how lines are integrated to existing shapes?

Here, we show the Pen tool in action:

OK, so we have established I am not crazy :slight_smile:
The shape was imported from a sketch export from Fusion 360. Let me find the file format. I can’t remember off the top of my head.

17

Not crazy indeed. But this is not normal behavior so I couldn’t sort out what you were doing differently than expected. Good on you for carrying on.

Doing an experiment it seems that creating a line at the start of any curved line results in an extension of the curve rather than a new line segment.

I’m surprised this would have been missed until now so slightly odd. Not sure when this behavior was introduced.

@Rick Appreciate if you could review and confirm.

By the way… a potential workaround until something more definitive is found:

  1. create a single line segment not connected to the existing shape
  2. select node edit tool
  3. drag each end node of the line segment and connect to existing shape

The file is a DXF.
Export.dxf (3.6 KB)
After importing it I broke it all apart (using the node editor I&B) as I only wanted that section (well 3 of them, but they all have the same issue).
That work around you said works, to a point. It will still not fill the shape.

Can you upload the “fixed” file?
