"Snappy", more snap points for CamBam plugin

[EddyCurrent]

David,

There is a Null reference.
It looks like the order in which plugins and file geometry are loaded makes a difference.
If you load the file using the file menu then we know all the plugins are loaded and ready to use, but if you use load from project icon then things might be different.

Yes, maybe it is because in the V1 the snap to object snap also to the mesh object nodes, and there is a lot of points !. maybe the list of points to snap to is not "finished" when the plugin is loaded ...

I wonder if the problem can be when you read the state of the "snap to object" to reflect it in the plugin form to update the checkbox ; I have not read your code (I no longer have C# installed), is this checkbox updated in the "init plugin" or only when the form is opened ?

... and the strange thing is that today, it works like a charm

David,

The plugin waits until CamBam top window has loaded then it checks for the snap toolbar and grid toolbar, hooks into the mouse, gets stored settings from Windows Registry. form loads and sets check boxes using stored settings.
After that it uses the mouse position and detects any entities it passes over, however it does update itself first to get the latest version of any file CamBam has loaded.

// need these here to get instance of newly loaded file
view = CamBamUI.MainUI.ActiveView;
myfile = view.CADFile;

I don't know the mechanism used when a file is loaded from it's icon rather than using File->Open from withing the software.

Hello,

Ok, so it’s a mystery ! 

Yesterday I launched the file 6 times without problem.. and on the 7th time, the error message appeared... no big deal, given that in the end it still works if you click on "continue" ...

New version attached to the first post in this thread, V 8.9
Instead of hiding the cursor at a snap point it will change the cursor to a Cross.

I shall leave v 8.8 in place so you can choose either.

Thanks Eddy.  I just mentioned something like that as an option in the cnczone group the other day when I pointed out the disappearing cursor bug was the potential issue they were having.  With the cross we will still be able to use other functions until the value gets reset.

Bob,

I saw your post on cnczone the other day and liked your idea.

Just tried the new version.  I like it.  Thank you.
