Create best fit profile

Warning: Upon review of Autodesk Best Fit profile tools, there does not appear to be a workflow that would result in design as acceptable WisDOT design standards. Therefore, WisDOT does not recommend using the provided tools, but rather use an alternative workflow instead. Only pursue the Best Fit workflow if there's a significant need.

Info: This workflow will be mostly hand drawn, with curves being created using K Value inputs.

Open drawing file

1. Quick Access > Open
2. Open File dialog box
   1. Look in: browse to folder dataset is saved.
   2. Select AliProf-CtyE-prfl-creat-bst-fit-begin.dwg
   3. Open

Create proposed profile

1. Ribbon > Home tab > Create Design panel > Profile dropdown > select Profile Creation Tools
2. Select profile view to create profile: Left-click profile view.
3. Create Profile dialog box
   1. Alignment: CthE
   2. Name: type Cty-Prop-Best Fit
   3. OK
4. Profile Layout Tools toolbar > Tangent-Tangent tool dropdown > select Draw Tangents
5. Specify start point:Shift + right-click > Endpoint OSnap > Left-click CthE-Exist profile start point.
6. Specify end point: Left-click a point at top of curve.
7. Specify end point: Continuing to the right, left-click a point at the middle of slope.Tip: If you need to adjust one of the tangent's slopes, but not the other, use the triangle grip point that is in the direction of the slope that needs to be maintained.
8. Right-click to end command.
9. Profile Layout Tools toolbar > Vertical Curve tool dropdown > More Free Vertical Curves > select Free Vertical Parabola (PVI based)
10. Pick point near PVI or curve to add curve: Left-click near PVI
11. Specify curve length or [Passthrough, K]: type KEnter
12. Enter K value or [Length, Passthrough]: type 45Enter
13. Enter to end command.
14. Graphically make adjustments, left-click and drag grip points.
15. ESC

Create tangents that do not meet at PVI point

1. Profile Layout Tools toolbar > Tangent Line tool dropdown > select Fixed Tangent (Two-points)

   All points are eye-balled, graphically picked.

2. Specify start point: Left-click a point near incoming tangent's endpoint.
3. Specify end point: Left-click a point that follow the length of the slope.
4. Specify start point: Left-click a point near the endpoint of previous tangent.
5. Specify end point: Left-click a point extending past the curve.
6. Specify start point: left-click a point at start of outgoing slope.
7. Specify end point:Shift + right-click > Endpoint OSnap > Left-click CthE-Exist profile end point.
8. Profile Layout Tools toolbar > Vertical Curve tool dropdown > select Free Vertical Curve (Parabola)
9. Select first entity: Select on incoming line.
10. Select next entity: Select next outgoing line.

    Tip: If commandline is not asking for K Value, type KEnter to change the command.

11. Enter K value or [Radius, Length, Passthrough]: type 175Enter
12. Select first entity: Select on incoming line.
13. Select next entity: Select next outgoing line.
14. Enter K value or [Radius, Length, Passthrough]:Enter
15. Select first entity: Select on incoming line.
16. Select next entity: Select next outgoing line.
17. Enter K value or [Radius, Length, Passthrough]: type 53Enter
