Toolpath loses reference to object

[francois (adolphe fr)]

Hello

I was saving file regularty in CarbideCreate build 514 and then I repanel2.c2d (468.9 KB) opened the file (to undo some modifications).
When doing the simulation I noticed that few objects are not rendered anymore.
Looking at the toolpath list , all toolpath are still present. When I go over the toolpath name with the mouse it does not focus anymore on the related object.I checked and the toolpath is not disabled.

For example in the image above I lost my panel cutting toolpath.

Looking at the project file itself I can see that "elements " list is now empty for few toolpaths I have previously created

“TOOLPATH_GROUP_OBJECTS”: [
{
“TOOLPATH_OBJECTS”: [
{
“automatic_parameters”: true,
"elements": [
** ],**
“enabled”: true,
“end_depth”: 3,
“name”: “Panel cut”,
“ofset_dir”: 1,
“speeds”: {

I had to fix it manually in the file by I adding back to the toolpath the corresponding object uuid

The issue occured for few toolpath only and they were still fineuntil I reload the file.

Any idea?

I have attached my project file.

I have created two tools. I cannot attach .csv file for my tools database file so here is the content of the csv:

I was able to assign toolpaths so as to get:

save, close, and re-open the file and it previewed as:

Perhaps @robgrz can look at your file and determine what’s up.

Hi Will

thanks for your reply.

Do you mean you manage to load the file and everything ok without any modification?

Could you pleas save the file used in your screenshot and send it back to me . I will try to reopen it.

By the way I can see you are using build 515 and looks like I am only able to download 514. Can it make a difference?

Thanks

No, the toolpaths were missing as you described — but I was able to add them, save, close, and re-open and they were then still there.

I don’t think 515 changes anything to address this, but it might. It’s currently in beta:

Hi Will,

Thanks. I found how to reassign the toolpath with the GUI instead of modifying the toolpath.

1. Double click on a created toolpath
2. Select objects you want to assign the toolpath with
3. Click on ok on the toolpath dialog.

if I lose my toolpath assignment I will able to do it that way.

Thanks
