MTO creation in AVEVA PDMS

Material TakeOff(MTO)
Introduction
       Material Take-Off (MTO) is a term used in engineering, piping and construction, and refers to a list of materials with quantities and types (such as specific grades of steel) that are required to build a designed structure or item. This list is generated by analysis of a blueprint or other design document. The list of required materials for construction is sometimes referred to as the Material Take Off List (MTOL).
        Material take off is not limited to the amount of required material, but also the weight of the items taken off. This is important when dealing with larger structures, allowing the company that does the take off to determine total weight of the item and how best to move the item (if necessary) when construction is completed.

AutCAD - Start a Command

There are various command in AutoCAD to Draw, Modify, Annotate, Daft etc.
To start new command in AutoCAD there are different ways.
1.      Command Line – you can enter shortcuts of COMMANDS.
2.      Ribbon Icon – Click on the specific icon assigned for a COMMANDS.
3.      Menu bar – go to a menu bar and access required command from various menus.
From all above options most convenient ways are Command line shortcuts & ribbon. You don’t need to remember command line shortcuts for every command. Some practice with command line shortcuts may help you to guess a shortcut. This certainly helps to save time by using shortcuts in command line for a large plot files.
SPACE BAR/ENTER will quick start previously used command.
You can also use arrow kyes to access previously used commands in that file.
Press F2 to open command line tab to go through commands used so far.
Also prompt is provide as you start typing command in the command line (From version 2014)
For a ribbon the commands are divvied into different panels to differentiate its application like home (Draw, modify, modeling, view), annotate, visualize, parametric etc.
Slowest way to access commands is the menu bar. Every time you need to access menu bar to open a new command. This will certainly slow down your performance and efficiency.

AutoCAD - Prospective views

Prospective view
      Prospective view drawing is an approximate representation or image as it is perceived by the eye on a flat surface like paper.
Characteristics of prospective view
  • Smaller as their distance from the observer increases
  • Foreshortened: the size of an objects dimensions along the line of sight are relatively shorter than dimensions across the line of sight.


All prospective drawings assume a viewer is a certain distance away from the drawing. Objects are scaled relative to that viewer.
An object is even not scaled properly, a circle often appears to be ellipse and a square can appear as a trapezoid. This distortion is referred to as foreshortening.
A prospective representation of a scene that includes parallel lines has one or more vanishing points in a prospective drawing. Any number of vanishing points are possible in a drawing, one for each set of parallel lines that are angled relative to the plane of drawing.

Types of prospective:

One point prospective view
            One vanishing point is typically used for roads, railroad tracks or buildings viewed so that the front is direct facing the viewer. Any objects that are made up of lines either directly parallel with the viewer’s line of sight or directly perpendicular can be represented with one point prospective view.
