What is the best way to draw this shape

Hi.

My level is beginner.
I have CorelDraw X5 installed and I have to draw this shape:

Here is the specification:

I used the Freehand tool but I can't understand how to assign distance between nodes or position of nodes.
So what is the best way to draw this shape ?

Regards.

  • Hello Tsvetan Filev; You can make that without any problem. Draw a line and with the "Shape Tool" add as many nodes as you like to start with ( you can ad or delete as needed ) then move the nodes to where you would like the center of the bar to be, and then outline with "Contour Tool" to the size you want, brake the drawing apart and delete the center line or just move it in case you want to edit it later.
      It is the basics of drawing in CorelDraw you may want to get some video learning aids that are out there and start learning at the beginning. Corel is a lot of fun to use once you know how to do the simple things. One of the places you can go to get videos on Corel is Foster's web site ( http://www.unleash.com ) He comes here often and is easy to get in touch with.

  • Hi,

    I would start with an upper case U from the font Greasyspoon and covert it to outlines (Ctrl Q) I would then size it proportionally and then step it, flip it and join the two to make up the first set. Then step and repeat to make up the group. Add the line at the top and or bottom. Select all and combine (Weld). This is how I would do it. There may be an easier way but it will get the job done.

     

    Good luck.

    I have a quick question.  I have worked with flex circuits in the past (back in the late 70's/early 80's) and the biggest hassle was to work the bends in, in order to compact the circuit strip into the confined space -- an engineer's biggest headache.  It wasn't just a matter of quick folding, but having to determine the additional material needed for each radius at the bends.  Trigonometry and Calculus Super Angry -- my worst enemies.  Anyway, I ramble on . . . the question is: How thick is the strip after all the layers have been stacked and epoxy-sealed?  

    You show a 0.4 (I am assuming inches) gap between each fold but not the actual thickness of the piece.

     

    Edit:  Just saw Hendrik's post.  So he beat me to it.  Yes

    • Hi Graewerld.

      Well you are right, I need this image in order to produce eps file for the etching process.
      All sizes are in mm.
      Bends are not a problem.
      I will make small bords and then use hot bar soldering http://www.miyachieurope.com/technologies/hot-bar-reflow-soldering/
      in order to connect the boards using copper strips. (Sounds very high tech and complex Wink )

      My flexible printed circuit will use material with the following parameters:
      = 25 um base material kapton
      = 25 um adhesive
      = 70 um copper
      I will use this one http://www2.dupont.com/Pyralux/en_US/products/laminate/FR/pyralux_fr.html

      0.4 mm is the gap between two folded tracks.
      The track itself is 1.8 mm wide.
      I'm not sure what is the best radius for the corners.

      Regards.

    • Here is my suggestion:

      1.  Draw a rectangle.

      2.  Draw small rectangles and lay them according to the plan over the first rectangle.

      3.  With the Smart Fill tool click once on the first large rectangle.
