Be care from Picasa and think to change BLOGSPOT to WEB it's better for your publishing and you can't depend on from picasa.
Thanks for All.

Again I am writing about useful tools how to convert a PDF drawing to DWG but in this post is about online.
PDF files are hard to edit and change. This is especially true when it comes to drawings converted into PDF, which are almost impossible to edit without using specialized software. AutoCAD is one such software that can be used, but it is also fairly expensive software that not everyone owns or can afford to have.
That is why we are going to present to you witha great toolfor converting PDF drawings into AutoCAD format files.
Cometdocs is a free online file converter, storage and sharing tool. One of its supported conversion formats is PDF to AutoCAD. The tool can be used for free with and without registration. Registration offers more possibilities, like storing files of up to 1 GB online and sharing them publicly or privately with friends. Overall, it is a neat tool and that is why we are going to present you a tutorial on how to use it in converting PDFs into DWG or DXF formats.
The first thing you need to know is that the tool supports PDFs designed with AutoCAD software. Once you are at the Cometdocs website, click on Add/Drop files to upload your file.
Wait a couple of minutes for the file to upload and then drag the file to the Convert tab. A list of available conversion formats for that file type will appear. Scroll down the list to choose your desired format, in this case DWG or DXF.
As you can, see the list is pretty comprehensive and lots of formats are offered, including MS Word and Excel, ODT, TXT and more.
In addition, if you are a registered user at Cometdocs, all of your converted files are automatically stored in your account, enabling you to share these files with friends using Cometdocs’ sharing capabilities, or simply keep the files stored in the cloud so that you will have access to them at any given time online.

I am fanatic about rules , I'll try always to be attentive during dimensioning so I publish some basic rules in dimensioning.
1. Each feature of an object is dimensioned once and only once.
2. Dimensions should be selected to suit the function of the object.
3. Dimensions should be placed in the most descriptive view of the feature being dimensioned.
4. Dimensions should specify only the size of a feature. The manufacturing method should only be specified if it is a mandatory design requirement.
5. Angles shown on drawings as right angles are assumed to be 90 degrees unless otherwise specified, and they need not be dimensioned.
6. Dimensions should be located outside the boundaries of the object whenever possible.
7. Dimension lines should be aligned and grouped where possible to promote clarity and uniform appearance.
8. Crossed dimension lines should be avoided whenever possible. When dimension lines must cross, they should be unbroken.
9. The space between the first dimension line and the object should be at least 3/8 inch (10 mm).
The space between dimension lines should be at least 1/4 inch (6 mm).
10. There should be a visible gap between the object and the origin of an extension line.
11. Extension lines should extend 1/8 inch (3 mm) beyond the last dimension line.
12. Extension lines should be broken if they cross or are close to arrowheads.
13. Leader lines used to dimension circles or arcs should be radial.
14. Dimensions should be oriented to be read from the bottom of the drawing.
15. Diameters are dimensioned with a numerical value preceded by the diameter symbol.
16. Concentric circles should be dimensioned in a longitudinal view whenever possible.
17. Radii are dimensioned with a numerical value preceded by the radius symbol.
18. When a dimension is given to the center of an arc or radius, a small cross is shown at the center.
19. The depth of a blind hole may be specified in a note. The depth is measured from the surface of the object to the deepest point where the hole still measures a full diameter in width.
20. Counterbored, spotfaced, or countersunk holes should be specified in a note.
