Parallel objects

Anonymous

How can you check if two objects are parallel (e.g. the short edge of two rectangles)? And if you find out that they're not parallel, how do you make them parallel? I tried making two rectangles parallel by mirroring the first one, but it would be useful if I could check (and useful to know how to select two edges of two different shapes and make them parallel). I have parallel snaps switched on but it often tries snapping to lines that I'm not trying to snap to.

>>So you make two lines parallel<< 

 

 

Another possibility you can see >>here<<, but this is only a snip of a powerful tool (Parametric).

Assuming you want to draw a parallelogram: 

>>Here<< you can see how to use the osnap "Parallel". 

 

If this doesn't help you, show us an example what you want to do (What do you have and what do you want to achieve).

Hi, 

 

Why don't you use geometric constraints to set parallel condition.

How do I do that?

Perhaps a better way for me to describe it is that I want to put two shapes side by side and I want the edges which are facing each other to be parallel at exactly the same angle. I saw a video about using the rotate command, pressing shift, right-clicking and selecting parallel, but I can't get it to work.

See my 2nd video above.

Didn't you see my videos above. At what point you can not follow the shown steps? What doesn't work for you? 

 

You can have two different situations: 

 

1. The geometry is already drawn and you want to make two lines parallel. 

- command rotate, select geometry to rotate

- pick any base point

- Choose Reference option

- pick two points which define the angel of the geometry which you want to rotate

- Choose the 2Points option

- pick two points which define the angle to which you want to ratate.

 

2. You want to draw new geometry (e.g. a line) parallel to an existing geometry. 

- start the line command

- define the start point 

- when you are asked for the second point activate the PAR osnap (or set the running osnap to PAR)

- hover the cursor over the geometry which shows the destination angle (do not pick) until you see a small cross

- move the cursor away until you see a temporary track parallel to the existing geometry

- define the needed distance (pick any distance or type a value). 

 

Both variants are shown in the videos above. Look at them carefully ...

Hi, 

 

Go to Parametric - Geometric 

In this select parallel option and then select any two objects (lines)  to make parallel.

You should try this from Lee-Mac,

http://www.lee-mac.com/objectalign.html

The full title will say align to a curve but it also will work on lines.  Didn't test it on a pline.  Not on a computer atm.

How about just using ALIGN with those edges, and then Moving one of them away if you don't want them touching?

For the quick test:

Measure the angle between the two lines, that are supposed to be parallel to each other.

If they are, AutoCAD will show it as text, otherwise it will show the degree of the angle.

If the angle is 0°  the lines are NOT parallel!

E.g.: The value might be 0.4° rounded down to 0°.

 

(By the way: If you want to see any / or more decimal places, you can set the amount you want to see with AUPREC)

Measure two points from one line to the 90 degrees of the other and if they are the same they are parallel.

Modify the distance of the one set of points to be the same as the other distance and that way you can force the lines to be parallel.
