  1. Hi there! I've got a drawing in Acad 2010 which consist of about 6000 lines. The image is a ship, and I need the drawing to insert in a HMI screen. Now my problem: The accomedation of the ship is white, as is the background of the sheet. I need the drawing with a black background, but want to keep the white color of the accomedation of the ship. When I change the backgroundcolor of the sheet to black, the white areas inside the drawing will also change into black. If I trie to hatch the white areas inside the drawing the program gives a messages that there are to many open bounderies. I tried to make a blok of the drawing and move it on a black square, but then again the white areas will turn black. So for short: How can I make the white areas non-transparent without using the hatch-command????? Thanks in advance!!
  2. This is more of a trigonometry question, but I want to know if there is an easier ACAD solution for drawing. In the given triangle of ABC (sides and angels are known) I want to draw line CM so that the area of BCM becomes 2000 cm (are of ABC is 5311.7 cm3). Is there an easy ACAD way for drawing this line without using trigonometry for calculation?
  3. How can it be that a hatch object has no area property? Using the AREA command, it says the object has no area. None shown in properties. None listed using vlisp (vla-get-Area Obj). I have seen this before, but could never figure out why or how it happens. Any thoughts?
  4. Hello, I am working in AutoCAD 2010 and am looking for a LISP routine to report the area of counterclockwise polyline loops as a positive value and clockwise polyline loops as a negative value(as with the right hand rule). For example, if I have a poly line that crosses over itself multiple times creating several loops of different areas with the majority of the area coming from clockwise loops I would want the total area reported as a negative value instead of the absolute value that is reported in the propertes of the line. Does anybody know of anything that fits the bill? Thanks
  5. Hi, Im trying to do a polygon with a parametric constraint, the Area. How can i maintain the same area with differents side values? The polygon is the Trapeze. The dimensions are: 54 (biggest side) 28 (small side) ~23 height Tks a lot
  6. Does anyone have a lisp routine that can create a polyline from a given area & one given x or y distance? We have a list of room areas that we must have the exact SF & fit several of these rooms into an existing floor plan. It is very tedious to change a vertex to get the SF.

    AREA Command

    I just got a quick question about the AREA command. So if I use the AREA command on a solid then the number it spits out is the surface area of this solid right? Let me know when you get the chance. Thanks
  8. So I am trying to get the area of the 2D gear face I just made. I tried doing it the way stated: "Tip. A fast way to calculate an area bounded by several objects in 2D is to use the BOUNDARY command. With BOUNDARY, you can pick a point within the area to create a closed polyline or region. You can then use the Properties palette or the LIST command to find the area and perimeter of the polyline or region." but the BOUNDARY command did not work and it gave me an error of "valid hatch boundary not found." Is there a better way to figure out this area or any way that I can fix this error. Your help will be greatly appreciated. Thank you.
  9. Hi everyone! I'm kinda new in this LISP world and I'm having some trouble on this project of mine. Here we go: I need a LISP to draw a PLINE and create a text with the PLINE's area. The area is always different and I don't have the points to draw the PLINE, so I have to draw it with the mouse and when I finish I want to have the area value in a text placed inside that PLINE (I can place it with a mouse click, but I don't want to have to write the area). This is the code I already wrote: I would appreciate any help! Thanks!
