According to me,Link sculpting is one of the advanced link building techniques that you can apply directly to your website. Essentially, given that a search engine knows that your site has value then you can have some influence about the context in which your site has value.
Using nofollw was am advanced SEO link sculpting activity that grew in popularity in 2008 and the start of 2009 but it was never something that we advocated. The idea was to add a "nofollow" command to internal links that you did not want Google to take into account when interpreting your website. Nofollow is a syntax that Google and other search engines collectively came up with as a way for a website owner to say to a search engine that they do not have any opinion on the relevancy of the page they are linking too.
This basically directing the page juice to your most important page. Usually, the highest PR and the best page is the home page, now, you may want to redirect all of its juice to a particular page where you have your offer.
Link sculpting is the act of optimizing your pages to flow PageRank from your highest PR pages through to your most important internal pages..according to google, search engine robot does not crawl links with the nofollow attribute,PR sculpting is the utilization of the nofollow tag within links.
Link Sculpting is the process of blocking the link juice to pass to the pages which are linked to your page. For example if you provide a no follow attribute for a page which has a link on your site then it is called link sculpting.
