Trimble Link for Civil 3D 2012

April 22, 2011

Trimble Link for Civil 3D 2012 has been released.  The earlier version seemed to work very well with C3D.  Since last release, 2011, they incorporated the functionality into the ribbon.

You can download Trimble Link for Civil 3D 2012 by clicking on the image below:

Tip

Recycle between open drawings in AutoCAD P&ID and Plant 3D by holding the “Ctrl” key down in your keyboard and clicking the “Tab” button on the keyboard

Closures, Separators, screens, Strainers, and Steam Traps on the P&ID

Temporary Closures for process operation or personnel protection are shown in the P&ID

Separators, Screens & Strainers should be shown upstream of equipment and processes needing protection. Strainers collect solid particles in the approximate size range 0.02-0.5 inch, which can be separated by passing the fluid bearing them thru the stariner’s screen. Typical locations for strainers are before a control valve, pump, turbines, or traps on steam systems.

If the location of the Steam Traps are known they should be indicated. For example, the trap  require upstream of a pressure-reducing station feeding a steam turbine should be shown.

Steam traps on steam piping are not otherwise indicated, as these trap positions are determined when making the piping drawings. They can be added later to the P&ID if desired, after the piping drawings have been completed.

Driplegs are not shown, unless told otherwise.

AutoCAD Plant 3D ViewCube

ViewCube tool is a navigation tool that is displayed when you are working in 2D model space or 3D visual style. With ViewCube tool, you can switch between standard and isometric views.

The ViewCube tool is a persistent, clickable and draggable interface that you use to switch between standard and isometric views of your model. When you display the ViewCube tool, it is shown in one of the corners of the window over the model in an inactive state. The ViewCube tool provides visual feedback about the current viewpoint of the model as view changes occur. When the cursor is positioned over the ViewCube tool, it becomes active. You can drag or click the ViewCube, switch to one of the available preset views, roll the current view, or change to the Home view of the model.

The ViewCube tool is displayed in one of two states: inactive and active. When the ViewCube tool is inactive, it appears partially transparent by default so that it does not obscure the view of the model. When active, it is opaque and may obscure the view of the objects in the current view of the model.

In addition to controlling the inactive opacity level of the ViewCube tool, you can also control the following properties for the ViewCube tool:

  • Size
  • Position
  • Display of the UCS menu
  • Default orientation
  • Compass display

The compass is displayed below the ViewCube tool and indicates which direction North is defined for the model. You can click a cardinal direction letter on the compass to rotate the model, or you can click and drag one of the cardinal direction letters or the compass ring to interactively rotate the model around the pivot point.

Diameters & Wall Thicknesses of pipe

The size of all pipe is identified by the nominal pipe size, abbreviated ‘NPS’, which is seldom equal to the true bore (Internal diameter) of the pipe-the difference in some instances is large. NPS 14 and larger pipe has outside diameter equal to the nominal pipe size.

Pipe in the various sizes is made in several wall thicknesses for each size; which have benn established by three different sources:

(1) The American National Standard Institute, thru ‘schedule numbers’

(2) The American Society of Mechanical Engineers and the American Society for Testing and Materials, thru the designation ‘STD’ (standard), ‘XS’ (extra-strong), and ‘XXS’ (double-extra-strong), drawn from dimension established by manufacturer.

(3) The American Petroleum Institute, through its standard 5L, for ‘Line pipe’. Dimensions in the standard have no references for individual sizes and wall thicknesses.

‘Manufacturers weight’ were intended, as long ago as late 1930’s to be superseded by the schedule numbers. However, demand for these wall thicknesses has caused their manufacturers to continue. Certain fittings are available only in manufacturers weights. Pipe dimensions from the second and third source are incorporated in American National Standard B36.10M.
