"Snappy", more snap points for CamBam plugin

[EddyCurrent]

I have a fix for that but it might have to wait a day or so for an update.
The fix is to find the Centroid of each entity, if the X value = NaN then the entity is invalid and
should not be included in the entity list to further process.

Edit: new version 8.7 attached to first post.

Thanks, Eddy!
But this got me thinking wouldn't it be better that a check for invalid objects is built into CamBam when opening a file ... or an option in the 'Edit' menu for example.

Well... in a sense there is a detection system.  It reports the error! <grin>

It seems 'Snappy' does not account for hidden layers. In a project I have two hidden layers with a lot of 2D objects and two other with a 3D object in each. And the drawing of a new object on another visible layer slows down CamBam work to almost unusable speed. Several second of waiting until cursor reacts to mouse movement.
Seems to me logical that hidden layers should be ignored.

[EddyCurrent]

Agreed, new version 8.8 attached to first post, ignore hidden layers.

[Dragonfly]

That was fast 
Cheers!

Hello

Strange, I do not have this behavior with the V8.7 ; no snap to object on hidden layers(*), and also no snap to locked layers  (maybe locked layer can't be handled because snappy is 0.98 compatible)

(*) maybe I don't understand well ; it snap on hidden objects or it's only slowed down ? (I always disable 'intersection' in the snappy window if I don't need it because it seems that it's what slow down the things on large drawings)

In 8.8 it's like this;

Code: [Select]

foreach (Layer layer in myfile.Layers)
                        {
                            // use visible layers only
                            if (layer.Visible)
                            {
                                foreach (Entity ent1 in layer.Entities)
                                {


and thanks David for keeping the plugin web page up to date.

I should have mentioned that snapping does not occur but iterating through all objects slows down CB very significantly. When there are many - in my case an imported .dxf produced by a 3D CAD program where every single line and arc is a separate entity.

[EddyCurrent]

That is correct and I would very much like it if Andy would add more snaps in the 'correct' manner to prevent slow down.

Dear Eddy

I have come across a problem with Snappy when loading a large surface model - 50 Mb plus (with CB1.0). I have attached the Unhandled Exception report. The error occurs at loading the CB file, if I remove the Snappy plugin - no error.  The CB file is too big to also attach.

Any thoughts?

Geoff,

Is there any particular checkbox that causes the problem ?

[GeoffreyGRoy]

Dear Eddy
Good question, I have discovered the following:

(1) The problem  relates to "Snap to Object", if I disable this option the problem does not appear.  The other options seem to have no effect.
(2) The problem only appears if I load the CB model by <double clicking> it, If I start CB, then load the model the problem does not seem to appear!

Geoff,

Snap to object goes like this, it just calls CamBam's internal method for setting snap to object.

Code: [Select]

// snap to object
        private void checkBox5_Click(object sender, EventArgs e)
        {
            CamBamConfig.Defaults.SnapToPoints = !CamBamConfig.Defaults.SnapToPoints;
            checkBox5.Checked = CamBamConfig.Defaults.SnapToPoints;
            CamBamUI.MainUI.ViewContextMenus.RefreshCheckedMenus();

            // if snap toolbar button plugin installed, update button
            if (Params.object_button != null)
                Params.object_button.Checked = CamBamConfig.Defaults.SnapToPoints;
        }

Hello

Today I fell on a problem that seems related to snappy plugin, CB give an error when opening the file, but strangely, the problem appears ONLY if the file is loaded from its project icon, if loaded through the file menu, no problem. If I remove the snappy plugin, the error disappears.

All snap features in snappy are disabled except "snap to object".

I attach the file that give this error.

Win7 64 bits, CamBam 1.0 32 bits

edit: I just see it is the same problem reported by geoffrey, (file is 30Mb) .. if snap to object is disabled the problem go away too ...

edit2 ... and the problem do not appears all the time ... just after I writed this post, the problem as disappeared .. and I change nothing in the file 

seems it appears one in two launch ...
