2d countour invades object

[nubrandao]

Does the 2d strategy ignore model?

I usually do some tests with form tool 52r5.5 to go undercut for the second operations, to operator check of is ok the center and position.

I noticed today that the toolpath in somepoint was invading the component, i had to show a smaller Edge. Why this could happens? Does the toolpath ONLY respect the countour select ?

Another thing, in link tabs, i input entry and exit 10mm with 90 degree, perfect entry, but if trim tool and i select toolpath, it cuts the entry tool, the tool does strait in Z Axis on the SIDE i cutted, does trim tool cuts entry and exit links?

Yes

The paths like 2D contour/adaptive/pocket are not Model aware, they just follow the selected contour.

The Trim tool cuts the toolpath and any extensions that were applied, it still applies the same links and lead though.

If you are using trim with a polygon you need to allow for this in your  selection.

When trimming with a plane or boundary you can add an additional offset:

Is there any 2d toolpath model aware?

[a.laasW8M6T · Accepted solution]

2D chamfer is sort of model aware in that it can avoid hitting the model with the side of the tool in most cases

so is better to stop using 2d contour on incline walls, if the wall is straight, i can use 2d counter

if not, 3d contour

That is correct, I wouldn't recommend using the 2D Contour toolpath on Inclined walls, 3D contour is the better solution here.
