Cylinder Axis checking

9:35 AM, Monday January 24th 2022

Hello,

I'm working on the 250 cylinder challenge and I have a question. I've drawn my cylinders and I would like to check if the alignement is correct.

It is said in the instructions that I should take a pen of a different colour and try to ignore the minor axis that has already been drawn. My problem is that I don't see how to ignore the axis. As the minor eIlipses shoud be cut in half in the middle I tried to use the ruler this way. I place my ruler in the middle of the first ellipse and measure the space in centimeters. I divide the figure in 2. I place a point. Then I do the same for the other ellipse. Finally I use the points as marking and trace minor nb2 (the one with a different color). My problem is that this method doesn't seem to work.

Could someone please share his/her tricks when placing the ruler for checking? How can I be sure that my ruler is on the right place and is going to help me to draw the correct minor axis?

Thanks very much in advance for the help!

Why don't you rotate the page until the minor axis become horizontal? After that, estimate the center of for each elipse, and draw a line perpendicular to each minor axis.

Thanks for answering my question

I took back my page and tried as you said to put the minor axis horizontally but then how do I know wich one is correct?

Any comments on my try to find the center is welcome. Thanks again for your help!

Could someone please have a look (using the link I put above) to my work on cylinders and give his/ her opinion if I've done the checking correctly?

I've made the challenge once but I could get the badge because my axis were not correct in my cylinders and also because I didn't know how to check.

Thanks in advance for remarks and critics.

The Art of Brom

The Art of Brom

Here we're getting into the subjective - Gerald Brom is one of my favourite artists (and a pretty fantastic novelist!). That said, if I recommended art books just for the beautiful images contained therein, my list of recommendations would be miles long.

The reason this book is close to my heart is because of its introduction, where Brom goes explains in detail just how he went from being an army brat to one of the most highly respected dark fantasy artists in the world today. I believe that one's work is flavoured by their life's experiences, and discovering the roots from which other artists hail can help give one perspective on their own beginnings, and perhaps their eventual destination as well.
