Placing an entity at an angle to a line
« on: September 04, 2017, 02:39:41 PM »
I thought this would be easy but have hit a brick wall !  :-\
The entity is a group of parallel lines with a handle at the point it will be connected.
The entity has to be accurately placed at a specific angle on the end of a line which itself is at an angle in the drawing.

Thanks

WorkingPlane works in 2D too. Set your original line to horizontal, then create your new lines angled from that.

Alternatively, presuming that your line angles to the right:

  1)   Use Rotate command to rotate your selected entity the desired angle. (handle doesn't matter)
  2)   Set 2 new handles (Cntl-H) for your entity, the first at your connection point (RMB), and the second horizontally to the left (right if your line angles to the left) any random distance from the first handle (shift-LMB). 
  3)   Execute the move command (M) with "Original Scale"checked and "From Reference Point" unchecked.
              set the first point on the end of the line     (gravity = RMB)
              set the second point anywhere on the line ( line snap =  "k" key).

Later, take a look at the M macro here, so you never have to use handles again.http://forum.designcadcommunity.com/index.php?topic=322.msg1404#msg1404

pnb,

Your description is too vaue for me to know what you are trying to do. 2D? 3D?

In any case, the best way to reposition an object to any angle anreferenced to any point is to use multiple handles.

From the point you want to move the object to, draw a guide line to another point at a known angle (2D or 3D). You can do this by drawing a line and rotating it the desired angle(s) in 2D or 3D. If you want to move the object so it is aligned with an existing object just use a point on the other object for your guide.

Set the first handle at the reference point on the object to be moved (the drag handle).

Set the second (and third) handle(s) at the desired direction from the drag handle with respect to the object (distance is irrelevant).

Move the object, setting the first point at the place you want the object moved to, and the second (and third) points at the end of the guide lline(s) or to pints on another object.

Now the object is positioned at the proper position and angle.

This works without changing the working plane, and you do not have to to a bunch of math or constructions to figure out the angles to rotate the object.
