Create a line with length and angle

[simsiem]

Hi,

I am in the draft workbench with an empty file. There I do the following.

1. Select the line tool.
2. Select a start point anywhere.
3. Select the angle checkbox.
4. Set the angle to -75 deg (actually, the value does not matter).
5. Set the length to 0,2m.
6. Press enter and enter again to confirm this coordinate.

Nothing really happens. But if I do the same with a length of 200mm, a line is created. It also works for a length of 1m or 1,4m, for example. Thus it seems the leading zero is a problem.

Do I do something wrong? Can you observe the same?

Best regards

Simon

You have to type in 0,2 as a length. When you type ,2 it won't work. Freecad needs the 0 before the comma. Is this the solution for your problem?

Hi Willem,

I did it exactly as I wrote it with a leading zero. The problem still exists.

Hello Simon,

I'm getting the same issue. In fact I'm struggling to get a line with any value, using the input fields. I managed to make it work once, that's it.

I have had some issues using different navigation styles when using the task pane for Draft tools.

Normally I am using touchpad, but when I get into trouble in Draft task panel I briefly change to Open Inventor or Cad.

For this though I do not seam to get any result this way, could however be related.

I confirm I have the same problems. I also discovered that when I change the length in the Combo View the line in the drawing react as expected for values above 1 but when I use a value smaller than 1 the line in the drawing freezes

The observation of Willem was very interesting. I tested the issue further and found out that the algorithm has not a problem with values < 1 but with the procedure of beginning the entering of a value with 0. The computations are performed with every key press. Thus entering 0,2 calculates the point the first time for the length value 0. And the algorithm seems to stop or crash, when 0 is entered.

I created a bug for tracking this issue: http://www.freecadweb.org/tracker/view.php?id=2860.

Hi guys,

Could this be a possible walk around? :

1. after you do

Select the line tool.
Select a start point anywhere.
Select the angle checkbox.
Set the angle to -75 deg (actually, the value does not matter).

set the length to a > 1 value like 10,2;
2. after you create the line, go to property->draft->length and change from 10,2 to 0,2, by deleting "1" in front of "0".

Can this avoid the

stop or crash, when 0 is entered.

??

And it's already fixed!

Thanks a lot. I'll give it a try this weekend.
