Accudraw / Accusnap / moving elements relatively to other elements.

Hi.

I hope somebody knows and can remind me a method I can use to move the blue line parallel to line AB so that the lower end of the blue line ends up at the same elevation as the upper end of the red line. I don't want to use any construction lines just AccuDraw and AccuSnap and tentative snaps.

I knew a way of doing this in the past, but it has escaped my mind now and am unable to figure it out.

  • see my video of how I did it at  Basically  I used accudraw with copy move parallel, BTW I used different colours so look at the video...

    So with  move copy  parallel no copies select the  red line and snap to green vertical line at top end keyin  O  for origin then keyin RQ to rotate the  compass and snap to align to bottom end of green  so we are locked in the X plain  now as I move the  mouse  left  ( or westerly ) the  red line moves down the  angled yellow line  or your AB line  when its inline with the  green vertical and still parallel to its original position a projection will be shown  when and where  the two locations coincide..... unfortunately I started in a 3d file,   I expected the  projection to show as a dashed highlight maybe its my  settings .. no matter it still shows where the coincidence  occurs... so just data point where  it happens and  then I tested it was right  by  drawing a line  locked in the that plane from the  the top  of the green and as shown in my video it worked...this last step was not  needed I just  wanted to prove to the video audience that it truly was in right spot...

    I  captured the actions  with audio using the  free app "Jing..."   great fun doing it  so enjoy and  look at the video .. just  click on the  link above  where it says

    screen cast.com and it will take you to the video then click on play ... you may need headphones to hear the audio ... again enjoy....

  • I did find it  quite difficult to know when exactly the  coincidence was even zoomed in  because you said you didnt  want any construction lines I could not  use the  keyboard input snap for intersection as the  projection  is not snapable  .. 2 out of 3 times it was off by a few mm  just using  by  eye when its on off tipping  point..which you saw in the video is quite hard....

    However  if you allow us just  one construction line,    a horizontal line left of your   vertical red line top endpoint then using the same method I out lined  before when  your  close  you can enter i for intersection and it it finds the  point exactly every time  sub mm perfect...

  • Hi Lorys.

    Yes, using the MOVE PARALLEL command for solving this problem is a "proximity" method as AccuSnap ignores the line being moved when the AccuDraw origin is re-defined inside the command, but just seeing how much effort you put in answering my question, including the video clip and all, I didn't dare to point this out in my previous message :).

    Another limitation is this method works on pretty much single segment lines only. If we were to use it to move a cell, which I work with all the time, MOVE PARALLEL wouldn't work. I forgot to mention this important detail in my original message.

    I think I will not be able to do this without having to draw one construction line.
     
    But thanks a lot anyway.

    Yes I found the same  problem, it was hard to do as you made the restriction of no contruction lines to be used, but for  moving lines , using  just one   horizontal construction line  it does work with my method very nicely and  does it very accurate with accudraw as shown in the video method .... as for cells

    try rotate the  view in line with line AB then draw construction line offset from CD to the red line  now use move command to move the cell instead of parallel use enter when moving the cell right to left and the cell can only move horizontally parallel to AD ( like orthomode in acad) or axis lock in msnt.. I havent tried this yet just  ran it through my  mind... but seem logical and should work with cells.. ( centre or origins snaps)
