Power Dimensions

AutoCAD® Mechanical software offers powerful dimensioning tools that enable designers to use abbreviated dialog boxes to

control only the relevant variables when creating dimensions. This advanced dimensioning method adheres to standards, making

adding, deleting, and editing dimensions of parts and assembly drawings quick and easy. With automatic dimensioning, users

can create multiple dimensions with minimal input, resulting in instant groups of ordinate, parallel, or symmetric items that are

appropriately spaced. Smart dimensioning tools force overlapping dimensions to automatically space themselves appropriately

while integrating tolerance and fit list information into the design.

Arc Length and Jogged Radii Integration

The arc length and jogged radii dimension types have been integrated with power dimensions, adding the following benefits:

• Breaking Dimensions—Overlapping dimensions make an appropriate break in one dimension line to   allow the two

dimensions to fit in the same drawing correctly.

• Arrange Dimensions—When users select a group of dimensions, this command organizes

and arranges the dimensions to meet drafting standards and make the drawing more readable.

• Align Dimensions—Use this command to take a group of disparate dimensions and organize

them in a straight line or arc to make a drawing easier to understand.

• Format Dimensions—This feature adds special commands in  AutoCAD Mechanical to give

users more formatting options.

• Insert Dimensions—When one dimension needs to be quickly split into two separate dimensions that are properly aligned

and arranged, this is the command to use.

• Join Dimensions—Easily merge several dimensions into a single, accurately spaced dimension.

• Edit Dimensions—This powerful command enables designers to edit a whole group of dimensions simultaneously to help

reduce inconsistencies and errors.

• Power Erase—Eliminating dimensions is easier than ever with this command that automatically

adjusts remaining dimensions to maintain proper spacing and presentation.

• Check Dimensions—This command highlights each dimension where the true value has been

manually overwritten.

• Chain Dimensions—Quickly set up and create a set of chain dimensions that are arranged and

spaced with precision that can be difficult and time consuming to achieve by hand.

• Baseline Dimensions—With minimal effort, insert a group of dimensions that are all based off one

anchor point in the drawing, correctly spaced, and following the user-defined drafting standard.

• Drawing Scales—Skip lengthy manual workflows to change dimension styles because these intelligent dimensions

automatically adjust to changes in the scale area or title border scale.

Dimension-Driven Design

This dynamic feature turns dimensions into a design tool, where changing the dimension updates the geometry of the design.

Users can now select multiple parts or entities across the entire drawing to be updated when the dimension changes. Designers

will find frequent opportunities to use this tool, for example, where one area of the design needs to grow or shrink by a certain

distance.

The AutoCAD Mechanical Advantage

To compete and win in today’s design market, mechanical engineers
need to create and revise mechanical designs faster than ever before.
AutoCAD® Mechanical software, a purpose-built design application,
saves countless hours of design and rework by automating common
tasks. As a result, designers gain a competitive edge and can spend
their time innovating rather than struggling with workfl ow issues
caused by generic design applications. Sharing design information
accurately and effi ciently with team members, customers, and
suppliers is also a key part of getting designs to the manufacturing
fl oor. AutoCAD Mechanical is based on the AutoCAD® platform—the
world’s best-selling design application—and uses the native DWG
format, providing access to the largest design community worldwide.

2D Mechanical Structure

With mechanical structure, you work more intuitively and effi ciently in a design environment
that enables you to easily express and revise design intent.


Increase Your Productivity

When creating mechanical designs, using
software not specifi cally developed for
mechanical engineers often requires spending
valuable time on manual workarounds to get
the job done. Since AutoCAD Mechanical is
built for mechanical designers, it improves
the design experience by simplifying complex
mechanical design work. Designers can easily
express, revise, and reuse their designs because
intelligent parts and assemblies are used to
document designs instead of lines, arcs, and
circles. In addition, a complete set of drafting
tools can automatically dimension an entire part
and instantly arrange a design with accurate
spacing and scale. And with the automation
of many common tasks, designers are able to
boost their productivity and reduce the hours of
rework caused by design changes.


Reduce Errors and
Inconsistencies

When designers create mechanical drawings
using generic applications, errors and design
inconsistencies can be easily introduced, wasting
time and money. AutoCAD Mechanical provides
support for local and international drafting
standards and includes an immense library of
standard content, enabling users to produce
consistent drawings that are easy to understand.
As an integral part of the Autodesk® solution
for manufacturing, AutoCAD Mechanical allows
detailers to natively and associatively document
3D parts and assemblies from Autodesk
Inventor® software. This associative workfl ow
automatically synchronizes drawings with the 3D
model, which reduces errors and inconsistencies
and saves hours of rework. Clear and consistent
communication in the design and documentation
process helps companies avoid delays and errors
on the shop fl oor, keeping your company ahead
of the competition.


Streamline Design Tasks

Once a design is complete, it is important to
share accurate design and part information
with the teams responsible for ordering and
manufacturing the product. Using generic
software for these tasks often means creating
critical parts lists and bills of materials (BOMs)
by hand. And, even with the smallest design
change, manual methods can introduce
critical errors, resulting in delivery delays to
the customer. To help your company prevent
errors and costly delays, AutoCAD Mechanical
provides a BOM that is integrated within the
normal design workfl ow, so that parts lists and
BOMs contain correct part information and
all information is updated immediately when
a design change occurs. Accurate data enables
designers to work more effi ciently with other
departments and suppliers.

GEOMETRIC TOLERANCE By Dian pramesti, S.Pd

Geometric tolerance is the diversity of shape maximun allowable or perfect geometry of position. The term "geometry" refers to the diverse forms such as cone, cylinder, square. Theoretically, this forms a perfect shape, however, because it is not possible to produce perfect forms, then we need to determine the allowable diversity. Geometric tolerances determine the width of the tolerance zone where surface or the axis of the cylinder or holes should be used if the machine elements to meet accuracy.
If the tolerance is not given in the form of working drawings, so we assume that, regardless of the diversity of form elements and adjust the machine will function satisfactorily

Form and position tolerances or where controlling the properties of the diversity of forms, such as flatness, straightness, parallelism, ketegak lurusan, konsentrisitas, sphericity, angular displacement and so forth.
Auto Cad one program for drawing techniques, providing facility of geometric tolerance symbol on the working drawings.
  How to display the image geometric tolerances in working with Auto Cad drawings are:
1. Click on the tool bar dimension standards

ELEMENT MANUFACTURING MACHINERY By Dian Pramesti, S.Pd

Element manufacturing machine can make interchangeable machine elements made in various places can be put together for assembly purposes. That guide is that the elements of the machine will be in accordance with all of the other elements of the machine is an essential ingredient in the production of many. Without manukfaktur machine elements that can be exchanged, modern industry would not exist, and without an effective control measure, manufacturing will not be achieved.

For example, for car manufacturers who not only make contracts with other companies to make a machine element design to other companies to be made, but must also provide for the replacement of the machine elements. Machine elements in this case should be similar to that one of the elements of the machine will be in accordance with other machine elements. To make a similar machine element is something that is not possible. Machine elements can only be made very close to the level similar to a trillionth millionth of a millimeter, but such accuracy requires a very high cost.

Fortunately, the exact size is not absolutely necessary. The requirement for the degree of precision adjusted to suit various functional requirements.

The concept of quality in manufacturing tolerance machining is the most important factor. Products with little diversity in shape and size are considered high-quality products and can impose higher prices. Wastage will occur if the manufacturing process is not able to maintain the shape and size within the limits specified.

Granting an extension provision dimensional tolerance because tolerance to provide additional information about the shape, size and position of any part of a product.

Function of AUTO CAD programs often comes with giving basic dimensions and tolerances that can help the process of tolerance. Where to tolerance holes AUTO CAD users can type big letters on the back of the hole diameter was then given the number of quality of tolerance in accordance with the table, to pivot AUTO CAD can type small letters on the back of the hole diameter was then given the number of quality of tolerance in accordance with the table.

For geometric tolerance of a workpiece AUTO CAD can provide tolerance values ​​by clicking and then click tolerance dimension

necessity is the mother of all kinds of inventions"

The old adage says, "necessity is the mother of all kinds of inventions" are true, and a machine, structure, system or new equipment is a result of the requirement. If a new object truly needed and desired, people will buy it as long as they do otherwise.
Before the new objects of any kind are produced, certain questions must be answered: is there a market that may be open to such things? And objects or equipment can be sold at a price where people are willing to pay for it? If the market which may be quite large and the estimated selling price seemed reasonable, the inventor made a plan or corporate officers may choose to continue the development, production and marketing plan for the new project

A machine, the machine structure or a new system, or even an increase in the existing system, there must be in the mind of the inventor, engineer planners before it became a reality. The first concept is usually written on paper or as an image on a computer screen. Later the concept was to communicate to others through language in the form of hand-drawn images that sketch plan, while the plan was developed further, the initial sketch was followed by others such as sketch calculation

The engineers and planners must be able to create a plan sketches, counting voltage, analyzes the motion, measure the parts, making the requirements for materials and details the methods of production, making the layout plan, and supervise the preparation of drawings and requirements that will controlling a lot of details about the manufacture, installation and maintenance of finished goods. To carry out many tasks that the engineers use hand sketches freely. They should be able to take notes and communicate quickly to the relevant officers and officers pendukung.Fasilitas in hand sketching and drawing skills to work in
