Difference between Line and Polyline?

The Line and Poly line are two objects with difference properties in Auto-CAD. In the line command, every time we click, the part between two points are- an Independent unity but the part between the first point and the last point consist of multiple separated independent unities.

The Line command allows you to create single straight line or a chain of straight lines.

By using this command-

• We can make object where line is used.
• We can select one line among them to edit the drawing. However, In the poly line command- There is always a unity which cannot be separated. We can only operate the whole unity when executing attribute edition is done.
• With the Line command we can pick a start and end point and AutoCAD will draw a simple line connecting to 2 points. It can continue to pick points and AutoCAD will draw a straight line between the picked point and the previous point. Each line is an individual segment and can be modified independent of the other lines. 
• The POLYLINE command allows you to create “ground” objects that can be extruded, given line width on the screen, and can contain arc segments. In this command,
• We cannot give offset in single line. If we want to give offset in single line then firstly, we have to explode the poly line, and give the offset in single line. 
• The Poly line is clearly superior to the line and spline. It produces a joined line which is then easier to use for other functions like hatch boundaries and offsetting. It has the extra editing functionality of the multi-function grip. The poly line can provide all that the line and spline can – but without the associated inefficiencies. 

**For Example- In the specify object

• The Line specifies is only a part of it. While in the poly line it specifies the whole figure of drawing.
• The line command can only be used to draw lines and it is easy and simple to operate. " BUT " In the poly lines command, not only we can draw lines, but also we can draw arcs, besides we can add (Arc, Close, Length, Undo, Width)these options to the menu. 
• We can draw a poly line with changing - (Line weight and Arcs) 
• A poly line is just a series of line segments that are joined together to form a single object. 
• Line command can be use in 2D Drawings and Poly line command in 3D. 
• A rectangle created with the line command, consist of four separate entities. 
• In poly line command, A rectangle created with one continues poly-line would be treated as a single entity.

The distinction between line and poly line is-

LINE = 2D= OK

PLINE = 3D= OK

(CAN CONVERT POLYLINE BY COMMAND EXPLODE)

Therefore, If we use just  2D drafting will not have to use the poly line.

Uses of Curtain Walls in Revit

Curtain wall systems are typically designed with extruded aluminum members, although the first curtain walls were made of steel. The aluminum frame is typically infill with glass, which provides an architecturally pleasing building, as well as benefits such as daylighting. However, parameters related to solar gain control such as thermal comfort and visual comfort are more difficult to control when using highly glazed curtain walls.

 

Other common infills include: -

Stone Veneer, Metal panels, Louvres, and Operable windows or Vents.

 

A Curtain wall is which encloses the space within a building but does not support the roof.

Curtain walls differ store-front systems in that they are designed to span multiple floors, and take into consideration design requirements such as:-

Thermal Expansion and Contraction; building way and movement; water diversion; and thermal efficiency for cost-effective heating, cooling and lighting.

The Curtain wall systems are a non-structural claddding systems for the external walls of buildings. They are generally associated with large, multi-storey buildings.

The classification of types of curtain walling varies but the following terms are commonly used:-

Stick, Unitised, Panellised, Spandrel panel ribbon glazing, Structural sealant glazing, Structural glazing.

The general arrangement of a stick system curtain wall is:-

Horizontal and Vertical framing members(‘sticks’) are normally extruded aluminum protected by anodizing or power coating, but may be cold-rolled steel (for greater fire resistance) or aluminum Clad with PVC-U. Members are cut to length and machined in the factory prior to assembly on site as a kit of parts: Vertical mullions, which are fixed to the floor slab, are erecteds first followed by horizontal transoms, which are fixed in-between mullions. Mullions are typically spaced between 1.0 and 1.8m centres.

         

The framework are fixed infill units, which may comprise a mixture of fixed and opening glazing and insulated panels (which may have metal glass or stone facings). These units are typically sealed with gaskets and retained.

Building were constructed with the exterior walls of the building (bearing walls, typically masonry) supporting the load of the entire structure. The development and widespread use of structural steel and later reinforced concrete allowed relatively small column to support large loads and the exterior walls of building were no longer required for structural support.

The exterior walls could be non-load-bearing and thus much lighter and more open than the masonry load-bearing walls of the past. This gave way to increased use of glass as an exterior facade, and the modern-day curtain wall was born.

Early prototype versions of curtain walls may have existed in buildings of timber construction before the nineteenth century, should columns have been used to support the building rather than the walls themselves, particularly when large panels of glass infill were involved.

When iron began to be used extensively in buildings in late 18th-Century Britain such as at Ditherington Flax Mill, and later when buildings of wrought iron and glass such as The Crystal Palace were built, the building blocks of structural understanding were laid for the development of curtain walls.

Introduction of Revit Architecture, Structure, and System

Revit Architecture is a racy architectural design and documentation software application. Which is created by Autodesk. We can use Revit to create architects and building design as professionals. The tools and features of Revit Architecture is provide us simply and easily way to make special design of structure. Revit Architecture are most commonly use to support Building Information Modeling (BIM) workflow.

Revit is divided into three parts.

• Revit Architecture
• Revit Structure
• Revit system

Revit Architecture:

Revit Architecture is use to design a plan of building. In this we can innovate any particular room whichever we want to. It provide us many type of tools and features to maintain the plan and decorate the room.

Use of Revit Architecture:

Revit Architecture is used by architects for making plan for buildings before construction. It provide us to develop better quality of design and it improves our working project.

Revit architecture can be useful for those who are currently working or perusing career in architectural field. Revit architecture can be used for minimizing risk of misshaping and enable us to proceed our work in well planned manner.

Revit Structure:

Revit Structure is used for structural design of building. It is very important for construction. With the Revit Structure we can make better quality of structure design. With the Revit Structure we can make design with the column and beam. It is useful for structure designer.

Revit System:

Revit system is used for Mechanical, Electrical and Plumbing (MEP). Revit System is used for Mechanical, Electrical engineering.MEP Design is hard for design. In this we can make Air condition, heating and may be another device of mechanical. In the MEP we can make the electrical device.

In the Revit Architecture we can make multiple story building design in easily way. Revit is the best application for design of the structure, mechanical electrical and plumbing. It is very useful for making the 2D and 3D design, in this application we can see structure design in 3D very easily way. Revit Architecture is maximum support imperial value of design. 

 

In this application we can make easily any type of design in 2D and 3D. With this application we can easily decorate the design and we can see also. Revit Architecture is used to create accurate building design in the minimum time. If we are making the design in Revit Architecture, it’s save our maximum time.

Uses Of AutoDesk AutoCAD

AutoCAD is the most widely used software in drafting and computer-aided design (CAD) tool. It comes with different number of versions but across all of it’s versions it can be used from designing a small piece of jewelry or a small home to large buildings. It’s ability to imagine and render 2D objects and 3D objects and designs is unrivaled. Civil engineers also use this software to design bridges, roads, tunnels and other common buildings. Because this software allows the geography and topology of a site to be considered and included, as well as utilities and infrastructure. A civil engineer widely use a specific version of AutoCAD called, Civil 3D.
