Add Property

Introduction

This topic will explain the Add Property function, and the options found in it. This topic will also describe where to find the function, provide quick steps on how to use it, and provide links to related topics.

The Add Property Function

The Add Property function is used to assign thread values to particular geometry in order for BobCAD-CAM to read later when the geometry is chosen for features.

To open the Add Property dialog:

In the Properties group, of the Utilities ribbon, click Add Property.

The parameters display in the Data Entry Manager.

The Data Entry Parameters

Type

Thread - by default the thread type is selected to be assigned to the selected geometry.

Selected Geometry

(Delete) - removes the highlighted item from the list.

(Delete All) - removes all entities from the list.

The list box will list the entities currently selected for the function.

Thread Information

Thread Type - lists the current Thread Type associated to the feature. The drop down list will allow you to select from the Thread Types currently in your Thread Library.
Thread Size - lists the current Thread Size associated to the feature. The drop down list will allow you to select from the Thread Sizes currently in your Thread Library.

Add - assigns the properties to the geometry in the Selected Geometry list.
Cancel - exits the function.

Quick Steps - Add Property

Open the function.

The Selected Geometry list automatically has focus.
Select all geometry to be assigned a particular thread property.

The geometry is added to the Selected Geometry list.
Update the thread information to what thread type and size should be assigned to the selected goemetry.
With the correct geometry selected, and the proper thread information ready to be assigned, click Add.
Repeat as necessary for any other geometry needing other thread types and sizes assigned.
Click Cancel to close the function.

Example

Example File

The BobCAD part file for this example is available for download at: http://bobcad.com/helpfiles. If you are connected to the Internet, you can click the link provided to download and save the Mill Standard Drilling Example 1 BBCD.zip file. After extracting the zip file, you can open the file to follow along with this example. In the example file provided, the job, stock, and machine setup are already defined, but they will be unnecessary for this example.

Part 1) Adjust the layer visiblity

In the Layer Manager, click on the Holes layer to hide it.

This layer was used in the Mill Standard Drilling Example and will not be necessary in this example.

Part 2) Open the Add Property function

In the Properties group, of the Utilities ribbon, click Add Property.

The function opens in the Data Entry Manager.

By default the focus is on the Selected Geometry list and Selection Mode is active to allow you to add geometry to the list.

Part 3) Add Properties for UNC 3/8 - 16 Threads

Zoom into the part, and highlight the inner surface of one of the larger holes.

Once highlighted, click the surface to add it to the Selected Geometry list.

The geometry is added to the list.
Repeat the process for the remainder of the large holes.
In the Thread Information group of the Add Property dialog:
1. Leave the Thread Type defaulted to UNC.
2. Set the Thread Size to UNC 3/8 - 16.
Click Add.

The Properties are added, and the geometry is removed from the Selected Geometry list.

Part 3) Add Properties for UNC 5-40 Threads

Zoom into the part, and highlight the inner surface of one of the smaller holes.

Once highlighted, click the surface to add it to the Selected Geometry list.

The geometry is added to the list.
Repeat the process for the remainder of the small holes.
In the Thread Information group of the Add Property dialog:
1. Leave the Thread Type defaulted to UNC.
2. Set the Thread Size to UNC 5-40.
Click Add.

The Properties are added, and the geometry is removed from the Selected Geometry list.

This concludes the example.
