Testing: File upload

 

Just testing to see whether it's still possible to upload Excel spreadsheets and other types of files to the Geodesic Help Group, i.e., other than simple images like png and jpg files. This one is in response to a recent post by Ashok regarding shallow cap domes.

Here's the link to the original post on Christmas Day, 2018:

Is it feasible to make a dome out of a rotogrity?

Ashok Mathur <ashokch...@gmail.com>: Mar 06 12:32PM +0530 Dear Taff Thanks for this. In the meanwhile, I saw your animation in the 3D warehouse where you show the relationship between a dome and a rotegrity and have understood how to convert a rotegrity to a dome. I wish to convey my thanks and appreciation for the way the archives are kept. I wanted to see all the threads where I had discussed shallow cap icosahedron. Instead of using the appropriate keywords, I fired my name as the search term, and instantly I was taken back to a decade ago i.e. 2012 when I started to post in the group. Slowly I have been working up my way and have reached till August 2017. All threads are intact and very easy to read and copy out what I think is of long-term use to me. In connection with my new project, a twenty-foot radius dome as a restaurant, I have two points to make. Gerry had posted a spreadsheet for shallow cap domes of frequencies 2 to 4. For 4 frequency dome it shows that you use only 105 struts instead of 250 struts, which is big saving in material and labor. But as the floor radius is somewhat less, you need to input a higher radius to get get the correct (longer)lengths of the struts. For some reason, the pictures that Gerry had inserted in the spreadsheet have moved from their original positions and are obscuring the 4V strut length data. Can Gerry repost that spreadsheet or can it be corrected in the archive?   Secondly, Gerry had posted on Mar 28, 2017 another spreadsheet of a 3v dome that has a hexagon at the top. The pentagons do not have any struts in them and therefore make attractive window positions. Can I get another spreadsheet for a 4v shallow cap dome with a hexagon at the top? See another email I just sent outside this thread. Regards   Ashok

"ashokch...@gmail.com" <ashokch...@gmail.com>: Mar 05 11:01PM -0800 Dear Taff and Gerry Would 5/12 in Tommey.png be equivalent to a shallow cap division of a 4 v icosahedron? Regards Ashok On Tuesday, December 8, 2009 at 6:37:00 PM UTC+5:30 Gerry in Quebec wrote:

Gerry,

Upload (attachment) looked good.
My download worked fine.
Excel opened the XLS without errors.
All formula fields and images displayed correctly.

Dear Taff

The excel file comes through well but there is an issue to be kept in mind.

When the excel sheet is viewed in a browser. the images move and overlap data.

However, when downloaded and opened in excel, everything returns okay.

Regards

Ashok

Dear Gerry

Thanks for sending the spreadsheet.

The shallow cap uses only 130 struts (derived from the higher radius of about 22 feet) compared to over 200 in a hemisphere.

There are two other issues that I want to take up but will do from within their proper links so that the threads get updated correctly.

Regards

Ashok
