Structural Drawing

Posted on by blogger

This main thing has increased the ratio of its importance in any kind of development in structures.Structural Drawing deals with analyzing and designing of structures; basically it belongs to civil engineering. The designs of building and large non-building structures are involved in structural drawing. Structural Drawing is basically referred to drawing of wood, concrete, steel and other building structures. It clearly describes all the essential components which are involved in a construction of a building. The components could be in the form of columns, beams, pile foundations, slabs, roof framings, staircases and handrails. It also contains general notes whenever it is required for information on roof, slabs, staircase and RCC joints.

Structural Drawing involves various engineering and mechanical calculations which have relation to material physics and also it prepares structures which could bear heavy loads. These drawings are specially designed by professional CAD. CAD operators translate structural engineers hand drawing and also they sketch ruff paintings. You should make sure that it could obey the industry standards and codes.

Benefits Of Converting Paper Drawing By Computer Aided Design (cad)

Posted on by blogger

There are millions of drawings lying all around the world. These are invaluable pieces of paper, which have created monuments, buildings, machines and infrastructures. As the time passes by, these paper drawings are endangered being lost to disaster or being lost. There is an urgent need to make sure that all the paper drawings which are lying in offices, godown and secured places to be restored in a manner which will enable them to be with us for a long time.

The various means by which we can convert the old paper drawings to CAD are:
Automatic conversion using software
Manual conversion by draftsman
Precision redrafting
Scanning and storing

Of the above-mentioned methods, the cheapest method is to scan the document and store it in a computer. You can get it printed as and when you want it. There are numerous scanning companies all over the place who can scan large documents using highly complex scanning machine. You can scan any old documents and once scanned the document is there with you for lifetime. New York Document Scanning, www.new-york-document-scanning.com

If you plan to use the CAD file in future for making changes to the original design, which was done on paper, the best method is to get the drawing converted to CAD using draftsman with experience in CAD software. During this process, and as requested, text is re-typed and drawings are re-scaled 1:1. Specified items are also converted to different layers and colors to conform to the drawing standards. The end result of this meticulous process, being a CAD files which is identical to a drawing done on paper and which also requires no further work. http://www.convert2cad.com

Simple vectorisation is the conversion of a scan or raster image into a CAD or vector file. The process is achieved through the use of software that studies the raster image and tries to recognize and then replace the raster image with lines or vector information. The result is a dxf file, which is layered according to line thickness, line type and text. The image will require some manual clean up, the extent of which will depend upon: 1) The quality of the original 2) The amount of information required from the converted file. (Often clients do not require the title block etc.) 3) The quality of the line work and whether the text was typed or hand written.
BENEFITS OF CAD CONVERSION
Perfect drawings, which can be modified as and when required in the fastest possible manner.
Able to access drawings at a click of a button
Storage of the drawings becomes very easy
Can make multiple copies at no cost
Transmission of document is very fast
Multiple print can be taken as a very high speed
Thousands of drawings can be stored in a single DVD / CD
A new file, we can create as many layers as you require. We generate separate layers for dimensions, text, body, hidden lines, and centerlines, etc.
Text is separated and has its own layer and is recognizable as text
Dimensions are intact and are shown by a separate layer.
High accuracy
Normally create a drawing as a new file; the final output is editable and will be in DXF, DWG, DGN or any other CAD formats
Cost effective hand-drawn conversions.
The converted drawings are manually drawn with precision and are fully editable and contains:
Accurate layer information Accurate text (editable)
Accurate line types (editable)
Associative dimensions (adjustable)
Symbols & blocks of standard components Title blocks (as per scale)
Associative hatch patterns (editable)
Once you have converted the paper drawings to CAD format there are lot of thing that can be done with those dwg files. They can used to created 3D models and then generate rendered images or animation by using advanced software’s. http://www.convert2cad.com/samples.htm

Georeferencing & Cad Drawing

Posted on by blogger

To describe it now, georeferencing is a process of taking an image and assigning geographic coordinates to it or to georeference something means to define its existence in the physical space by establishing a relation between raster or vector images to map projections or coordinate systems. When data from different sources need to be compiled and used in any GIS application, it is important to have a common referencing system. This is brought about by using various georeferencing techniques.

The process georeferencing

Georeferencing usually refers to the method by which locations in raster and vector GIS files are related to real earth-surface positions.

Raster data is often taken by scanning maps or collecting aerial photographs and satellite images. Scanned map datasets usually do not have any spatial reference information. The location information delivered with aerial photography and satellite imagery might be inadequate and the data need not align correctly with some other data you possess.

In order to use some raster datasets in conjunction with other spatial data, you sometimes need to align or georeference them to a map coordinate system which can be defines using a map projection to display the curved surface of the earth on a flat surface.

Georeference a raster dataset means defining its location using map coordinates and assigning a coordinate system. This process allows it to be viewed, queried, and analyzed in comparison with other geographic data.

How can you georeference a raster dataset?

Add the raster dataset to be aligned to your projected data in ArcMap.

Add control points that connect known raster dataset positions to the map coordinate positions.

When the alignment becomes correct, save the georeferencing information (registration) for further use.

Though GIS users are familiar with the term ‘georeferening’, many of the CAD users are not much aware of the term and the use of gereferencing in CAD.

Why is it wanted?

A raster image has no particular size as it is made up of pixels. The size of the vectorised CAD/GIS drawing is determined by the raster’s pixel dimensions, without georeferencing. The image resolution (DPI) can determine this. This image size usually has no relationship with the size of the drawing that the raster represents.

A CAD file is usually drawn in a local coordinate system and depicts spatial information which can be drawn accurately without being fixed to a higher global coordinate system. However, when the drawing needs to be related to a higher level in a mapping context with data from many different sources, tools in ArcMap can easily reposition a CAD file and integrate it into that higher level without altering the CAD file.

First thing is to find out two points on the CAD file that matches with two points in the map for which we can use the Georeferencing toolbar in ArcMap.

Different tools on the toolbar can support different workflows and below listed is an easy way to describe georeferencing a CAD file.

First step is to load the CAD drawing and ensure that one of the CAD feature layers are listed in the drop down menu of the georeferencing toolbar.

Zooming to the place roughly on the map where the CAD drawing is to be related is the next step. You can use the ‘fit to display’ tool on the menu to fix the CAD file in the map frame.

ArcMap snapping helps accurate placement of the CAD file which makes precise selection of control points based on existing geometry. Use the ‘rotate’ tool if the CAD file needs to be rotated to get the drawing nearer to its final position. This enables easy picking of control points.

You can use the interactive scaling tool also for the above mentioned reason.

Now when you select the ‘update georeferencing’ option, this creates a .WLD file that will be read from now on to put your CAD file in the right place.

Finally, the coordinates are always adjusted into this physical place. Now you can select a equivalent system for your CAD drawing so that you can assign or project its coordinates with reference to the map or during any other geospatial operation.

Info On Dwg Drawing And Spider Web Drawings

Posted on by blogger

DWG – “drawing” is a format used for storing two and three dimensional design data and metadata. It is the native format for several CAD packages including AutoCAD. The DWG format is probably the most widely used format for CAD drawings.

DWG Drawing to PDF Converter allows you convert DWG to PDF, DXF to PDF directly without need of AutoCAD, it converts DWG and DXF files into vector PDF files, quick and easily. There are several claims to control of the DWG format. It is Autodesk who designs, defines, and iterates the DWG format as the native format for their CAD applications. The DWG format is probably the most widely used format for CAD drawings. Autodesk estimates that in 1998 there were in excess of two billion DWG files in existence. There are several claims to control of the DWG format. DWG Drawing to PDF Converter supports a wide variety of versions of DWG and DXF files, it supports DXF or DWG files. PDF converter is convenient and easy to operate, and DWG and DXF files can be directly dragged from Windows Explorer and converted fast.

DWG is a file format.
Applicant is not the exclusive source of files with the format name DWG.
Applicant does not control the use of DWG by others, either as a trademark or as a file format name.
The submitted survey does not reflect recognition of DWG as a trademark, since no distinction was made between use as a trademark and use as the name of a file format.
To tackle “spider web drawing means you must be capable of drawing straight lines. A spider web is not so easy to draw as it looks. If you are thinking of doing drawings of spider webs, take a look around outside to see if you can spot a good looking spider web. Do a quick, rough sketch outside then transfer it once you have a firm surface to draw on. After a bit of practice, spider web drawings were quite easy. For Drawing Corner Spider Web, you have to take your pencil and on the top of the page, about two inches from the right start drawing a line to 2 inches below the right top corner. The line should loop down and have points.
Draw straight lines from the points in your first line to the corner.
Make lines parallel to your fist line going all the way up. You should have 5 or 6 lines.
For Drawing Full Spider Web, Get a paper and make a cross on it, try to make both lines a similar length (using a ruler will help)
Draw diagonal lines through the center, dividing the paper up from 4 to 8 sections.
Start connecting the lines with inverted arcs, this is an arc), from the inside out.

Once you have reached the end of the web, elongate the diagonal lines, this will make it look like it has supports. Draw a spider by making a fuzzy ball, then drawing legs (eight of them) on your web. This spider web drawing in a tree looks quite attractive, a bit like a sailboat. The straight lines were probably the hardest part. You have to be careful while drawings the threads of web link up together neatly and spaced fairly accurately. Some spiders take pride in their homes obviously.

Steel Fabrication Drawings- Virtual Assembly Of Steel Connections

Posted on by blogger

Steel fabrication drawing is quite popular term used widely to satisfy the perfect building construction. It is a virtual assembly drawing that include list of part and material to be used in building. Natural disasters are occurring again and again so building stability is the main issue. To get the maximum building stability construction industry is paying more attention on steel connection of building. All the concepts and ideas can be evaluated using steel fabrication drawings. It gives the perfect idea of steel joints and dimension details to be used in building construction.

Steel fabrication drawings have their own importance and allow designers and fabricators to build effective building structure. It is widely used to get the pictorial presentation of building components to be used in building construction. Fabricators can identify how much material will be needed. So in the other manner it saves the cost. Pre fabricated building components like steel elevators, trusses, window and cabinet are widely used to get proper proposed structure. Once the building is completed it is not possible to make changes to satisfy the building stability in manner of steel beam and column connection. So to avoid this fabrication drawing is become the most vital term in construction industry.

The technique is also used to demonstrate important and necessary construction documents. To suggest steel member detail drawings, connection details, anchor plans, column connections and shop bolt summary fabrication drawing is most important factor. Professional steel detailers are also using it widely for maximum output in the term of accurate building construction.

In the construction industry specialize work should be appreciated. To satisfy this purpose reputed organizations have made international standards and codes must be used for steel fabrication drawings. All the steel fabricators and drawing experts are using these standards and codes for accurate drawing purpose.

For the outsourcing purpose it is also become popular term to save time and cost. After invention of CAD it is now become easy to convert handmade sketches in to proper design format.
