Machinist Apprentice | Fusion360 Geometry Projection Issues | Day 119

I'm working on the model car project again today and making good progress on it!

One of the things my boss wants for this model is to highlight the outline of the smaller features with an engraving. So like the outline of the doors, handles, and windows. The problem is, creating these features are a bit more difficult than you might think. Since the features I want to engrave aren't flat, I have to use a projection toolpath to generate the path I want the endmill to follow. However, I keep running into an issue where if it's got both steep and shallow surfaces that it needs to follow, it tends to have a delayed effect. 

Above I've got an example of the toolpath cutting into the material as it should at the beginning. However, when it comes to the curve, it cuts the air, then dips down, follows the curve farther along than it should, and completely avoids touching the material. I had this same issue with the rocket project, and the solution for that was to isolate the problem portions and create a manual offset by duplicating the toolpath. 

I published a question on the Fusion360 forums to see if other people have had this issue and found a solution. 

One thought I had was to project the geometry manually onto the 3D surface in the sketch environment and then use the trace toolpath. However, when I attempted to project it onto the vehicle, it would only project a short segment of the features (see picture above) and wouldn't take the whole thing. 

I'm still very lost on this and had to give up for the day. I'm trying to develop alternate solutions by drawing the geometry myself, but I've found that to be a complicated task, involving 3D sketches. 

While running the rocket operations, I got a low-lube warning light come on, and got the opportunity to fill it back up again! The process was pretty straightforward, just cut off the line to the air pressure and purge whatever's left, then unscrew the tank, fill it, and put it all back together.

However, when I went to fill the tank up with the Haas liquid grease (HLG) lubricant, I found they were two different colors. This really threw me off, and I absolutely did not want to mix anything and mess the machine up. I couldn't find any information about this online, so I ended up just calling Haas customer service and got my answer within minutes! It turns out they just switched distributors. The color change was just different dyes being used and had the same compound.
