Filling up one area with a "oriented" polyline.

Attached lisp file replaced due to the lack of (command) function vs (entmake) function... Now posted lisp should correctly work and on versions

Also, no matter that it's called snakefill-2linesboundaries-arc, it can be applied and on 2 curve boundaries as long as reference arc (half circle) would make intersections while copy-moving along horizontal/vertical curve boundaries...

Marko_ribar It's working!... I did some tests and I'm showing to you the result on the picture... I don't know, but, because the arc is so big to try to follow the boundary line, it could cause the situation 1. Also, following a arc as a reference line I miss a little distance of boundary line the situation 2... The boundary lines aren't a perfect lines as a arc, because it, I asked if it's possible to choose a pline to follow instead of a arc...

Grateful...

Marko_ribar,

As I told you, I'm trying to do it in the worst way!... But, is a good beginning to someone that is newbie in this kind of code!... I guess!...

Thanks again...

Another code, a little bit more simple than the latest!... It's necessary select the entity to copy, the begin of the first arc, the opposite side of reference line, fill up the radius of arc and number of lines...

Before to execute the code, you need to prepare the filled area, drawing lines 1, 2 and 3. Line 1 is the line to be copied; line 2 and 3 the side limits.

Edit: translated to english...

Hey!

Is a new member and saw a Lisp that makes it easier to draw underfloor heating.

Do not know, but can you point to a starting point where the heater starts and an end point where the heating pipe will stop? These two tubes are almost always short-lived each other. Thus the optimum would be a starting point an end point and then you draw with the mouse what surface you want under floor heating. As I said, I am a beginner.

Thanks in advance.
