Standard Mechanical Components

Overview

Use the LIBRARYPANELOPEN command.

BricsCAD comes with a library of more than 1,000 standard mechanical parts available in more than 170,000 different sizes. They are available in the Library panel, and can be drag-and-dropped from the library into your assembly. You can adjust the parameters in the Properties panel, which temporarily lists parameters of the component being inserted. After insertion, parameters can be edited in Mechanical Browser and the Properties panel.

In the Mechanical workspace, the Library panel contains all categories, including:
  • Standard Parts
  • Holes
  • Sheet Metal

Standard Parts

The Standard Parts category contains mechanical blocks grouped into 4 subcategories:
  • Fasteners, such as bolts, nuts, and washers.
  • Machine Parts, such as bearings, and sprockets.
  • Piping, such as pipes, elbows, and flanges.
  • Structural Shapes, such as beams, channels, and bars.

The content of each subcategory is structured by type, subtype, and standards.

Example: Standard Parts / Fasteners / Bolts / Hex Head Bolts / ISO / ISO 4017.

Note: There are 2 specific settings you can configure for Standard Parts in the Settings dialog box:
  • Thread representation (THREADDISPLAY) is used to represent (or not to represent) a 3D thread for bolts and nuts. This setting allows to decrease the memory consumption and increase the performance for large assemblies
  • Maximum number of sprocket teeth (GEARTEETHNUMBER) is used to limit the number of teeth for sprocket wheels (available under Standard Parts / SPROCKET). This setting allows to decrease memory consumption and increase the performance.
By default, THREADDISPLAY is set to Off and GEARTEETHNUMBER is set to 1, in order to optimize the performance of the model. When changed, the settings apply to all new documents.

Standard representation of thread in drawing views

Drawing views of your assemblies, generated with the VIEWBASE command, contain thread annotations for standard parts as thin lines for side views, and as a 270-degree thin arc for top/bottom views.

Example

Holes

The Holes category contains a parametric library of standard holes, such as slots, counterbores, and countersinks.

There is also a subcategory of Threaded holes, represented in drawing views.

Sheet Metal Form Features

The Sheet Metal category contains a parametric library of sheet metal form features, such as bridges and embosses.

Place a standard component into the current drawing

  1. Choose a category.
  2. Choose a standard.
  3. Select a type.
  4. Click on the desired standard component.
  5. Edit the parameters in the Properties panel.
  6. Click in the drawing area to insert the selected component.

As most standard parts are mechanical blocks, you can edit them using the BEDIT command. Additionally, it is possible to assign standard, category, type and description for custom standard part, and to override those properties for parts supplied with BricsCAD.

Old standard parts or standard parts inserted as mechanical components when mechanical blocks are disabled (MECHANICALBLOCKS=0), can be also handled.

If mechanical blocks are disabled (MECHANICALBLOCKS = 0), but a file with a mechanical root block is inserted with BMINSERT, a component definition is created using the internal name stored in the mechanical root, and corresponding properties are copied to that definition. If a definition with the same internal name already exists, this will be used.

In BOM tables, standard parts with the same name and parameters will be treated as equal even if one is an old component and another one is a mechanical block.

Create your own standard component

Use the CREATELIBRARYBLOCK command to create your own standard parts and add them to the Library panel.

Control the display of threads

  1. Open the Settings dialog box.
  2. Go to the Thread representation variable (THREADDISPLAY).
  3. Enable the setting.
  4. If applicable, update the document to make threads appear on existing parts:
    • Temporarily set Assembly components updating mode (BMUPDATEMODE) to [1] Update all components.
    • Use the BMUPDATE command to update the document.
    • If applicable, set the Assembly components updating mode (BMUPDATEMODE) to the previous value.

Control the number of sprocket teeth

  1. Open the Settings dialog box.
  2. Go to the Maximum number of sprocket teeth variable (GEARTEETHNUMBER).
  3. Set the value to be sufficient for used sprockets (500 is recommended).
    Note: Larger values slow down the update of standard sprockets. If the value is smaller than the required number, only that number of sprocket teeth displays.
  4. If applicable, update the document to make sprocket teeth appear on existing parts:
    • Temporarily set the Assembly components updating mode (BMUPDATEMODE) to [1] Update all components.
    • Use the BMUPDATE command to update the document.
    • If applicable, set the Assembly components updating mode (BMUPDATEMODE) to the previous value.
