Continuing on with the model it was obvious that I would need to flatten the front of the sides as the desired dash didn’t have those humps or overall protrusions on the bottom part of the dash.
I am beginning to get the sides and middle down to more of a uniform shell with a general thickness of 1.2mm. The backside edges and bottom are where the dash will contact or clear the floor of the interior. Most everything forward we can adjust as we need and it won’t impact the installation of the dash into the body and floor.
The original dash has a center section that comes down and contacts the transmission tunnel but rather than be centered it is offset to the left.
We need to add a center piece that comes down to the lowest part of the current dash and then we can use the full width rather than have it be offset. I used the left most side as the gauge for how far over to take it and pushed it to the same width on the right side.
I feel pretty comfortable with the overall shape we have right now. With these boundaries as a foundation we can start to really shape this model. Starting with the center section we can get a general shape. Using the various tools it is easy to add and take away shapes in Sketchup. We get a rough shape like this:
Now we can see how the sides will start to fit into the model correctly and we can start adding features to the center section like the controls and vents.
