I need to calculate the areas within a set of lines that form a closed area.
1. How do I do that?
2. Do I need to create a polyline around the area, or is lines enough?
I use AutoCad Map 2000i

View 1 Replies View RelatedTrying to calculate a catchment area to allow me to size some culverts using Civil 3D 2012 Sp#1.
" The specified location results in a Catchment with no area."
After sitting for 15 miutes I keep getting the above message. The surface is huge and there is an obvious catchment area (or I think it is obvious). The surface was generated from contours and cover an area of approx. 8Km x6.5Km but the catchment ares should be around 15-20% of that area.
I tried another one upstream about a Km and it worked fine. So the one I am doing now should encompass the upstream area as well as from that point downstream to the Discharge Point.
I have a drawing which contains about 100 "areas". These areas are closed polylines. I would like to get a total area of all these polylines.
I have tried using AutoCAD 2002's AREA command, but I am only able to select one item at a time, (AREA, Add, Object). This is fine for calculating a few areas. It gives me a running total of each item that I select.
Using the LIST command works OK for a few items, but you still have to wade through all the other information to get the area info for each item.
Is there a way to select crossing ALL the areas that I have, and have it return a total?
I've been trying to calculate large areas using fills but I keep encountering a problem with some of the hatches not showing an area and thus ruining my calculation. I've found out that I can correct it by removing certain crossing point between lines as is shown below in my screenshots. Is there any reason this is causing a particular problem and can I avoid it to save me having to go back over my hatches checking for these malformed hatches?

View 1 Replies View RelatedI'm using AutoCAD 2013 x64 and VS2012 Express with ObjectARX 2013. Now I want to calculate the (projected) intersection point of 2 (intersecting) lines in vb.net
After selecting the lines I have this line1.IntersectWith(line2, Intersect.OnBothOperands, intpts, 0, 0)
In Visual studio express 2012 I get the following warning for the above line of
warning BC40000: 'Public Sub IntersectWith(entityPointer As Autodesk.AutoCAD.DatabaseServices.Entity, intersectType As Autodesk.AutoCAD.DatabaseServices.Intersect, points As Autodesk.AutoCAD.Geometry.Point3dCollection, thisGraphicSystemMarker As Long, otherGraphicSystemMarker As Long)' is obsolete: 'Use the overload taking IntPtr instead.'.
So, if I'm reading this correctly, this method is outdated and I should use an other method to calculate the intersection. But I really don't know what 'Use the overload taking IntPtr instead' means.
One of the things I found is a function that contains this line of Dim inters As Point3d = line1.IntersectWith(line2)(0). This one looks almost the same, but doesn't give me the warning when I compile the code, but this method crashes AutoCAD when there is no intersection between the lines. This is despite a try catch block that surrounds the code.
For now I just want to use lines, but I need to expand the code so it will also work with circles, arcs and polylines.
I have about 30 profiles with water pipe lines that I need to measure all their vertical angles. since the vetical scale is exaggerated so I can't use the acad angular icon tool bar. Only thing I cant think of is to block each run then import them back in at 1/10 in y direction. How to get this done faster or more direct by any other methods.

View 2 Replies View RelatedIn the image below I have an aerial photo of an Island. I need to make it so as water areas are black and land areas are white (not greyscale) almost like a silhouette. My first plan was to draw round the island with a black paint brush and then use the "bucket fill" with a suitable threshold to fill all of the areas up to the black outline with black, however this doesn't work as the bucket fill either breaks through the black line or when I reduce the threshold, doesn't color the water areas solidly.

View 1 Replies View RelatedI'm struggling with the maths needed to calculate the angle between 3 points. My eventual aim is to use vba to draw a crescent shape polyline, ie 2 arcs curving in the same direction and joiing at their tips. Both arcs will have different centrepoints but the same radius. The only info I know so far is radius (R), centrepoints (CP1, CP2) and the intersection points where their end points meet (IP1, IP2). I've gotten those points by using the 'IntersectWith' function on two circles.
My coding skills are fine it's just the maths I'm struggling with and after searching google for quite some time I'm still confused. I've looked at loads of differnet formulaes and diagrams, but it always seems like they aren't complete. Maybe it's just me.

View 1 Replies View RelatedWhat formula Civil3D uses to calculate the average slope of a surface?
The formula I am using is S = I*L/A
S = Average Slope
I = Contour Invertval
L = Length of Contours (ft)
A = Area of parcel (sq. ft)
I just had to do four parcel calcs and the percentage I find using the formula is always 1-3% lower than the percentage Civil3D spits out. I can't find anything about how Civil3D arrives at that number, it just appears. I assume that Civil3D is more accurate but I can't give that number to a client without knowing how the program arrived there.
How do you calculate paint area?
We do a lot of chutes (for mining). They need to be painted on the outside only. They also need to be lined with rubber sheet on the inside. The area given in the physical tab in iProperties is the total area.
The area of the edges of the plates are small enough that we can ignore them, but is there a way to calculate half the model's area and get that result in the drawing in a text note?
