&lt;b&gt;Fun With Zwcad
1. Using 'Temporary Track' &lt;/b&gt;
&lt;b&gt;Adding a 'From' snap&lt;/b&gt;

Quite a few ex&lt;img src=&quot;smileys/smiley36.gif&quot; border=&quot;0&quot; align=&quot;absmiddle&quot; alt=&quot;LOL&quot; /&gt;Autocad users may be missing the 'From' snap and the 'Mid2points' snap. Well, the 'from' snap  is easy enough (For non-Autocadders: it snaps to a point a relative distance from  another point.). 

Let's say for example, you want to start a circle of radius 5mm, '10,25' mm away from the endpoint of existing rectangle:

1. Click on RECTANGLE icon ( or type &lt;i&gt;rec&lt;/i&gt;)
2. &lt;i&gt;[Type, as shown in italics, at the comandline] &lt;/i&gt;2Point/3Point/Ttr(tan tan radius)/Arc/Multiple/&amp;lt;Center of circle&gt;: &lt;i&gt;tt&lt;/i&gt;
3. Select temporary track point: &lt;i&gt;click on the selected 'reference' endpoint (of rectangle).&lt;/i&gt;
4. 2Point/3Point/Ttr(tan tan radius)/Arc/Multiple/&amp;lt;Center of circle&gt;:&lt;i&gt; @10,25&lt;/i&gt;
5. Diameter/&amp;lt;Radius&gt;: &lt;i&gt;5&lt;/i&gt;

Have fun!

<description>[QUOTE=Pavel][QUOTE=maker] Thanks, Rab.But, like I said, it would be better to load a 'mid2points' lisp routine. I found some on the net - but, for some reason, they don't load in Zwcad ;( 
This macros is working 
[CODE](setq p1(getpoint&quot;1-&#1103; &#1090;&#1086;&#1095;&#1082;&#1072; :&quot;)p2(getpoint p1 &quot;2-&#1103; &#1090;&#1086;&#1095;&#1082;&#1072; :&quot;)p(polar p1(angle p1 p2)(/(distance p1 p2)2)));'[/CODE] 
Good luck! 
 
or you can add this routine to your start up suite
 
(defun m2p (/ pt1 pt2)
   (setq pt1 (getpoint &quot;'nEnter first point: &quot;))
   (setq pt2 (getpoint pt1 &quot;'nEnter second point: &quot;))
   (polar pt1 (angle pt1 pt2) (/ (distance pt1 pt2) 2.0))
)
 
You can use this in the middle of a command by typing in &lt;strong&gt;(m2p)&lt;/strong&gt;.

<description>Thanks, Rab.
But, like I said, it would be better to load a 'mid2points' lisp routine. I found some on the net - but, for some reason, they don't load in Zwcad ;( Probably because some system variables don't work exactly the same.
It probably isn't too difficult to modify them to work on Zwcad. when I get the time I'll learn more autolisp and do it. I'll post the result here &lt;img src=&quot;smileys/smiley1.gif&quot; border=&quot;0&quot; align=&quot;absmiddle&quot; alt=&quot;Smile&quot; /&gt;

<description>Hello, Maker. Thank you for your share! Yes, That is fun and useful. With the feature of Temporary Track and compared coordinate, ZWCAD users can make drawing more precisely and conveniently. &lt;img src=&quot;http://www.zwcad.org/forum/smileys/smiley17.gif&quot; height=&quot;17&quot; width=&quot;17&quot; border=&quot;0&quot; align=&quot;absmiddle&quot; alt=&quot;T&#111;ngue&quot; /&gt;</description>
