How to: Editing Toolpath Associatively
Here are the basic steps to update the machining operations in VisualCAMc once part geometry changes have been made after machining operations are created. In the example below, changes made in Onshape, are automatically propagated to the VisualCAMc toolpaths!
Watch this short video to learn how associative edits of your Onshape part are automatically propagated to your CAM toolpaths in VisualCAMc.
1.Load a Part from Onshape into VisualCAMc and create your toolpaths. The sample part below has three toolpaths created (2-1/2 Axis Facing, 2-1/2 Axis Profiling and Hole Drilling).
2.Select the Part Studio tab to display your Onshape part.
3.Right-click on an Onshape sketch and select Edit.
4.Now select Top from the Onshape View Cube to see the sketch more clearly.
5.Edit a few sketch dimensions and then pick the check-mark to accept the sketch. We edited the coordinate location of all of the holes as well as the outer perimeter dimensions.
6.The Part will rebuild. Now select the Isometric View icon from the Onshape View bar to display the Isometric view
7.Now select the VisualCAMc tab and you will be informed that the part was reloaded due to geometry changes. The updated part geometry is loaded and displayed automatically..
8.You will notice that all of our machining operations are flagged in red text to let us know that they need to be regenerated due to the geometry changes.
9.Since the geometry changes modified the length and width of the part, lets update our Part Bounds Stock. Double left-click on the Stock icon in the Machining Job tree to display the Part Bounds Stock dialog. From this dialog pick the Calculate from Geometry button and then pick the Save button. The new stock size will display on the part.
10.Because our Stock dimensions have changed, we want to redefine the Work Zero to where we had it set it in Step 1 when we started (Highest Z, South West corner of the stock model). Double-click on the Work Zero icon in the Machining Job to display the dialog.
11.From the Work Zero dialog, select Set to Stock Box, Highest Z and the South West and then pick Save. This place the Work Zero where we had it before.
12.Because only non-destructive edits were made to the Onshape part, we can now proceed directly to regenerating our toolpath operations. Just right-click on the Machining Job and select Regenerate. All of our toolpaths are recalculated from the updated part.
13.Selecting each operation from the Machining Job tree will display the updated toolpath based on the dimensional changes we made to the Onshape Part model.
14.Now we will select Save from the VisualCAMc main toolbar to save our CAM Data to the Onshape part document. You must Save your document to save your toolpaths.
