Error at inside contour path

Post by herbk »

Hi,

i tried to get a path for a contour inside a part, but got only a Error Message. :(

Code: Select all

You did not give many details, so I may have missed the critical parameters. However, I had no problem at all with making an inside contour path.

Is the size of the opening large enough for the tool?

Hi Gene,

the tool is 3mm at diameter and the hole 30x20mm, - should fit...
No critical parameters, i just select the edges an click at the icon, - the way it works till now...

I just made this part to test the behavior which wsk8 describes at this thread
https://forum.freecadweb.org/viewtopic.php?f=15&t=51138
and which i can't remember that it works this way.

Sounds like it might be a depth issue. Is it Final Depth set correctly? ... and the other depth and height parameters?

Contour was integraed into Profile, did you use that? Please upload your file.

Hi Russell,

it's the same, no metter if i leave the depth and height parameters as they are or change it.

Atm i get in mind, that's a "very special" Problem...: Because Chris asks for the file, i want to be sure i don't make a misstake...
I repeated me work several times, each attemt i changed only one step of the workflow, - allways the same result.
At playing arroud with this i found one Issue more: My FC settings for the feedrates are mm/min. If i change the value for the Rapid Feed i get a wrong value shown ( i put in 500, shown is 30000 mm/min ). And i get the same Error message !

That suggests to me that the foult seams to be somewhere else. I made the whole model new, but by an misstake i made the size of the part a bit different and got no Error message and the inside path.
Trying again ( a new file, FC restarted) with the initial dimensions, the Error apers...

So i think i can say: i get the error only if the size of the part (outside) is 50x40mm, hole size don't matter...

I got exactly the same error messages when I used your file. Previously I had used a sketch and pad. That worked correctly.

Code: Select all

<Path.Area> Area.cpp(1318): project failed
<Path.Area> Area.cpp(1460): empty projection
Seems like something is not getting picked up correctly from the Cut shape.
