Invalid 2D point with mirror, WHY?

[harrison-matt]

Good evening,

 

I have been frusturated for over an hour now at why i can't mirror the last selection. AAAAAAAHHHHHH!!!!!!

 

Any good reason as to why would be great, I just cant get it...

 

(command "-osnap" "nea,mid")
 (setq p1 (getpoint "\nSpecify insertion point of valve: "))
 (setq r1 (getangle p1 "\nSpecify direction of flow: " ))
 (setq r2 (angtos r1 0))
 (command "_.insert" (block_name2) "s" scale p1 r2)
 (setq r3 (atoi r2))
 (if (>= r3 90)
   (if (< r3 270)
     (progn (setq ss (ssget "_L"))
(command "mirror" "P" "" P1 R1))
     )
   )

 

And please don't go and say this has been covered, if you know what it is just tell me, you don't even have edit anything.

 

Thanks:),

You're using an angle, mirror takes two points.

Ok, that was the last thing I tried. Lets say that you inserted the block at p1 then rotated it to r2. its just that the block is between these values: >= 90degrees and

Use the polar function or otherwise to define the second point of your mirror axis.

Use the polar function or otherwise to define the second point of your mirror axis.

 

(polar pt ang dist)

 

How would the distance work in the polar function?

Got it with out polar...

 

  (setq p1 (getpoint "\nSpecify insertion point of valve: "))
 (setq p2 (getpoint p1 "\nSpecify direction of flow: " ))
 (setq r1 (angle p1 p2)
r2 (angtos r1 0))
 (command "_.insert" (block_name2) "s" scale p1 r2)
 (setq r3 (atoi r2))
 (if (>= r3 90)
   (if (< r3 270)
     (progn (setq ss (ssget "_L"))
(command "mirror" "P" "" P1 p2 "y"))
     )
   )

To use the POLAR for your case, will have to input an arbitrary distance (i.e. 1.0) since you need to define only a direction between P1 and P2.

 

(setq P2 (polar P1 R1 1.0)
