    mind blown

    Imported models can carry color info with them (depending on import format). I've always had good luck by first using Model Prep > Clear Feature before trying to change the color of those.

    Mcam 2018 Mouse Wheel Issue

    I've had to uninstall the Microsoft mouse driver before because no matter what I did it always zoomed out at an uncontrollable rate. I haven't ran across anyone with the Microsoft drivers installed in a few years, though, so I'm not sure if it's still the case. After I uninstalled it, everything would work normally. The drivers didn't add any functionality, either.

    Thoughts on 3D Mouse?

    I'm a big believer. I'm a fan of changing the default behavior of the 3d connexion ones to Zoom Direction - Up/Down instead of Forward/Backward. In observing a lot of people I trained, it seemed more natural. Change my mind As far as model goes, if you're just starting out and paying for your own, it's worth the money to just grab the two-button "spacemouse," to make sure you're going to use it. If it's not your credit card, I'd recommend the Pro (the model without the LCD). Perhaps others have a different opinion, but I have a few-years-old model with the LCD and I don't think it adds anything. I'm already staring at enough screens, I don't need to look down at my mouse to see another! Edit: As for Motor-Vator.. Well, some men you just can't reach

    Arc Filter and tolerance input

    Correct, or at least, the vast majority of 'em. There are a few controls out there that will actually accept a 3d arc as input, but honestly the applications where it improves anything are extremely niche.

    Using more cores for multithreading

    There's two things that you may be thinking of. In Multithreading manager, you can specify the max number of THREADS (not cores) to run simultaneously, i.e., if you hit regen on 8 toolpaths, it will only process 4 at a time. Now, those toolpaths may be multithreaded and using N cores, but that's up to Windows to manage. You can turn it up or down, but you're unlikely to see benefits, as processing more toolpaths at a time means less system resources are available for each toolpath in the hopper. Now, if you wanted to actually limit how many cores Mastercam can use, you'll have to do that through the Task Manager. Go to the Details tab, find Mastercam and right click. Choose Set Affinity, and the box will pop up. By default, Windows allows us to use all cores available, but you can turn some off if you had some desire to (another CAD program needs some dedicated resources, toolpath regen is making your youtube cat videos skip, etc.).

    ‘Blended’ spline pattern, how to achieve?

    From the picture, I'd look at your linking parameters for that toolpath. It looks like it's trying to keep down between regions. Of course, best would be to post the toolpath, but it looks like you're not trying to contour/morph from the outer shape? In that case, you may have better luck with a Parallel toolpath, since that will offset one shape across the whole part.

    ‘Blended’ spline pattern, how to achieve?

    The key (which is only obvious in hindsight) is to create a Lofted surface, NOT a Flat Boundary surface. If you do a Flat Boundary there, it'll create a square surface and "cut" it out at the splines. The surface UV lines are still going left-right in that scenario, meaning that the curves that follow it will also be parallel. When you create a Loft, it's creating a surface that stretches from one spline to the other, so the UVs are going to be a transition as well. You can see this if you switch to wireframe mode after you create the surface.

    Select rectangle corners for drill operation Mastercam 19

    You're welcome sir. Glad to hear it!

    Select rectangle corners for drill operation Mastercam 19

    Window select will work, or you can use the quick mask buttons on the right of the graphics window:

    Interesting, so you're the one guy who was using entity selection with lines, eh? Not a direct answer, since no, you can't select lines the way you used to. I'd create points @ endpoints, then just hit All Points.

    Morph without pattern to

    You can do that, or hit the "Flip Step Over" button on cut Parameters to reverse the order. Parallel will always start away and collapse towards it, so it's useful if you want to use it as a scallop-style toolpath. I'm not sure why it's ordered that way, but someone long ago must have decided it

    Morph without pattern to

    I didn't look at the file since it seems like it was covered, but Husker is correct. When it comes to patterns, think of it like this: Morph - From one shape To another Parallel - Offset one shape Along Curve - Perpendicular to one shape (Parallel rotated 90°).

    Live 5axis programming question

    Edit: Whoops, I missed that Chris said this right above. Good call, Chris. Although of course nothing will replace real training , what you're looking for here is probably to just use a Surface High Speed, probably a Waterline? On the Holder page, just turn on "tilt to avoid gouge" After that, you'll get a gouge free toolpath, so for this simple example, it'll start 3 axis: Then quickly get to 5 axis as it needs clearance: You can, of course, do this with a Parallel toolpath or other multiaxis toolpath, but if you don't really need finite control or don't use it enough to remember what the settings do, why try harder?

    3 to 5 ax conversion smoothing

    All of the above points are true, but to get your original question on the smoothing option available to Convert to 5 Axis collision control option (and also Change Tilt Angle), what the tilt & rotary fields allows you to do is smooth out tilt relative to a selected axis. Say you're machining a cone with vertical cut outs. It's oriented so you're rotating around the Z axis. You may not want it to tilt into the cut outs (or at least, don't do it abruptly), you would set Rotary Axis to Z, then smooth the Tilt Angles. The values will be how much it's allowed to smooth the angles away from the original orientation. Maybe you'd say that the tilting is allowed to smooth motion out by ±15°. If it needs more tilt than that, it's going to tilt to clear, but it won't bother unless it's going to have to tilt more than 15°. You probably wouldn't need any rotary adjustment in this case since you're just tilting around a cone and it doesn't try to change the lead/lag, but the same principle applies for that. The other option here is to just to specify a blending distance like you've done. That will allow you to work backwards from where the tilt is and start applying it early. You'll still end up with the maximum needed tilt, but instead of applying it only when you need it, it will taper your tilt so it starts tilting X distance (in your example, 5mm) before it really needs to be tilted. So, picture a cut where you're perfectly vertical for most of it, but have to tilt 15° for an undercut that's 10mm long on one side of the pocket. Out of the box, the toolpath will remain vertical until you're going to collide, then it will start tilting, truly minimizing the motion, but possibly at the expense of having jerky motion on your machine. If you enter a blend distance, it'll figure out where it needs to start tilting, then work back by 5mm and start tilting there. You'll still end up safely clearing the part, but instead of that 15° of tilt happening over 10mm, it'll happen over 15mm.
