Please give some pointers and help with form tool

[fahey32]

Hi, I'm new to fusion and very new to direct modelling. I'm attempting to reverse engineer a panel from a 3d scan (it's for a 1st generation prius). I've watched a few youtube videos and read some posts in the forum. I've managed to thicken my form but the box display is pretty ugly and could follow the scanned surface better. I've been translating (via global coordinates) each of the nodes but am finding it difficult to move the nodes to where I want as I will adjust my camera angle to a view side on to the axis I am translating the node but then find that the line is then out of alignment. Straighten is too straight and pull seems to go to completely random nodes on the 3d scan mesh. How do I improve my topological optomisation?

Using the box display is a bad idea here, as it will only give you false promises that you're tracing the body correctly, but when you change to the smooth display, you'll be surprised that it's not following the mesh correctly as it seemed.

The box display is useful when having a self-intersection issue that is hard to detect, it will give you a clear and visible detection of the problem.

Now creating this using tools like pull can be helpful depending on the size of the effect area, meaning if you select the whole t-spline body with the pull command and hope that it will follow the mesh, it's not gonna happen, 1st because the mesh is messed up, and 2nd because the mesh has details that are not to be created in the form workspace but outside of it, so what is the right use of the pull tool? you can create a close approximation of the mesh leaving the openings and all other details for after you finish the form, and while you're working on creating the form, keep pulling the area where you're at in the modeling process to the shape, or finish the whole shape then start pulling different areas as you see fit.

I recommend using sketches if you want high accuracy.
