Surface Finish PMI : Dialog

Access: Open this function from one of the following locations:

  • Click the button in the toolbar.

  • Select Tools > PMI > Surface Finish from the menu bar.

Create PMI Surface Finish symbols and assign them to appropriate entities.

Creating the PMI Surface Finish symbols in the Modeling environment is very similar to creating the Surface Finish symbols in the Drafting environment. The main differences are as detailed in PMI & Drafting.

 

The dialog for the symbol is displayed.
The symbol dialog is initially displayed grayed out until the symbol is positioned in the graphics window.
The image below shows an example of the symbol with each element labeled.
The dialog elements for this symbol are described below.

Annotate the symbol either in the dialog or in the graphics window (once the symbol has been positioned).

To edit (or to re-position) a symbol after it has been created:

Double-click the appropriate symbol. The relevant dialog associated with the symbol is displayed. This means that you are now in edit mode.

Edit the symbol elements and/or re-position the symbol as required.

Example:Example:

Surface Finish symbols.

The surface finish symbols are usually labeled in microns as a Ra value or by grade numbers (N1 - N12). However, the values should be agreed upon with the designer and manufacturer, depending on the material.

Example descriptions and values:

Rough machining

1000 µ inch = N11 = 25 µ meters to
2000 µ inch = N12=50 µ meters

250 µ inch = N9 = 6.3 µ meters to
500 µ inch = N10=12.5 µ meters

2 passes of the tool. Finer finish.

63 µ inch = N7 = 1.6 µ meters to
125 µ inch = N8 = 3.2 µ meters

3 passes of the tool. Grinding.

8 µ inch = N4 = 0.2 µ meters to
32 µ inch = N6 = 0.8 µ meters

4 passes of the tool. Finish machining.

<1 µ inch = N1 = 0.025 µ meters to
4 µ inch = N3 = 0.1 µ meters

 

 

Terminator

Select the required terminator shape from the dropdown list.

With/Without Leader

Toggle option to display or hide the symbol leader.

Dialog Buttons

Set the required font size in the text.

Default = 5

Set the required font size in the text.

Default = 5

Font: Select the font type in which to display the entity. The five most recently used fonts are displayed at the top of the list.

Restore Default: Reset all values and settings to the system defaults.

Branch Leader: Add additional leaders to the annotation.

Example:Example:

Activate a break point of an existing leader.

Press the Branch Leader button and pick additional positions as shown below:

 

Delete Point: Delete the current entity from the annotation.

Switch Symbol Side: Flip the display of the annotation symbol to the opposite side of the selected entity.

Example:Example:

A PMI Surface Roughness symbol in the default location.

Press the Switch Symbol Side icon and the symbol is flipped.

If the normal at the picked point is normal to the M-View (defined plane), the symbol will be positioned according to the XY of the active M-view (plane,) and will be flipped along the X direction of the M-View.

 

Active M-View: Change the projected plane to a preset orientation by selecting the appropriate M-View from the dropdown list. From this point onwards, the projection of this M-View is the default projection for all new entities.

PMI M-Views can be added to this list as required.

Define Plane: Change the projected plane by picking a planar face, plane, or 3 points to define the active plane. From this point onwards, the projection of this plane is the default projection for all new entities.

A plane of any orientation may be defined.

Selection Mode (Reference Entities): Pick reference entities (points, edges, etc.) from parts outside the active assembly or part.

By default, if an assembly is activated, you can only pick reference entities from sub-assemblies or parts within the active assembly. Similarly, if a part is activated, you can only pick reference entities from the active part.

The button enables you to select reference entities from anywhere in the file.

OK: Accept the changes, perform the operation, and close the current dialog/task.

Apply: Accept the changes, perform the operation, and keep the current dialog/task open.

Cancel: Cancel all changes and close the dialog/task without saving the settings.
