zalo0:

Why did you post your question in a thread started by someone else about an entirely different subject?

What website are you referring to?  Is it the CADforum?  You did not bother to provide a link.  Anyway, I'm pretty sure you do not want to download the website as much as you do want to download the building floor plan. 

Why can't you download what you want?  Is it because the drawing file is not available or is it because you are getting an error of some kind?

If you are getting an error what does it say?

Hi, Am Praveen using AutoScan and AutoSteel by Newton Software Pvt Ltd are among the best civil engineering add ons for AutoCad while estimation of Bill of Material and reduce waste while cutting steel bars and many more. In simple words it saves my time as well as cost. check their website www.newtonindia.com for more details.

The easiest way is to use the DataExtraction wizard. For simple "Picture" legends you can also use our BLegend utility:

tesla: Then you obviously do not know anything about the TABLE command or how to obtain the data you need.

I can choose to extract data from ALL objects in the drawing or just from blocks with attributes.

I can extract such information as the length of lines or polylines.  I can extract areas of rectangles, circles and polygons.  I can extract diameters, radii, circumferences, as well as DeltaX/Y/Z data.

But it all comes down to what field the OP is working in and what information he is after.  Information that may be important to me (ex. - valve counts in a process piping diagram) would be of zero value to you.  Volume information would be important information for you to extract from a drawing while the same information would be useless to me.

Re: material specs.  If the information is contained within the drawing as part of an attributed block the TABLE command, used the correct way, can extract that information.

Hi John, when we create a 2D AutoCAD drawing, we use simple straight lines or geometric figures like triangle, rectangle, pentagon, hexagon, etc. for representing building elements. For example, when we draw a wall within the AutoCAD interface, we just draw two simple parallel lines. If we want to create a drawing of column, we simply use a square or rectangle to represent that column. So, from a 2D drawing, we get information about sizes in 2 directions (W x L) as well as area only.  

 AutoCAD does not allow us to utilize elementary properties of any object. Let’s consider the above example, here can’t utilize the elementary properties of the wall or the column. So, using AutoCAD users can’t generate volume or material specifications related data of an object, because heights and object properties are not there.

Hence, you can’t prepare complete automatic Bill-of-Materials sheet from AutoCAD Drawings.

tesla: What parameters will the user not be able to obtain information about?  Be specific.

Anyone who has used blocks with attributes and has access to a version of AutoCAD with the TABLE command can generate a bill of materials directly from their drawing.  No Excel required.  Refer to the information I provided in my FIRST post to this thread.

Hi anubhav1237, An AutoCAD generated drawing provides information about some parameters but not all parameters. So, 100 % data extraction (quantity extraction) is not possible from an AutoCAD drawing. AutoCAD does not allow you in producing any Bill of Quantities sheet automatically from a drawing. If you still want to get BOQ, you need to open an excel sheet and you have to enter all the parameters manually within the sheet, but this sheet will not provide you comprehensive BOQ data.

Another way of creating BOQ is you can use customized plug-in software’s which will assist you in generating well organized data or quantities automatically from an AutoCAD drawing.
