View 1 RepliesI 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
Trying 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?

I have an urgent need to calculate the foam fill inbetween two slabs on different planes. Also, the foam will come in 4x8' pieces. I am fairly good at family creation but am a little perplexed as how to start this one.

However when I try to calculate the volume I get this value: 3.6293E+12. I am guessing that it is saying this due to the fact its in millimetres, and I am trying to calculate a large area and convert in into metres squared. What this value means?
View 1 Replies View RelatedHow do you get the spacing you want for a hatch? For example if using ANSI 31if under pattern scale you have 1.0 what spacing does 1.0 represent? If you want your lines 1'-0" apart how to you know what scale to use other than trail and error?
View 1 Replies View RelatedI've tried (and failed) to create a fake slope label for line.
I've put in what I thought would be the correct formulas for it, i.e. rise/run.
This would mean putting Z1-Z2 / length, all of which you can get from a line.
But the result comes back showing the X, Y and Z coordinates divided by the length, even though I've only ticked the Z values in the co-ordinates.
I have a drawing with multiple layouts which is of a road plan and profile in 2 view ports.
When I publish the multiple drawings to DWF the 2nd viewport with the profile in it is completely black, but when I plot to DWF a single layout, it works fine which I don't understand. Surely the publish command publishes to DWF with the same settings as when you do a single plot to DWF, no?.
I have attached an example of the publish result.
I have a big drawing generated from a database with .NET containing about a 1000 parcels. Each vertex of each parcel has a label as MText. there are areas where these labels overlap partially. Is there a command to cycle through all areas where the overlapping occurs to speed up the cleaning process of the drawing?
View 2 Replies View RelatedI received a cross section file that was created in Micro Station and need to calculate the cut and fill of the project. There is no way to get the 3D files the cross sections were created from. Everything in the file is exploded and flat.
I was going to hatch under and above the existing grade to find the cut and fill and then thought about the scale of the cross sections. In model space the cross sections are 1=1 H and 1=10 V. When I do a hatch and get the area it is giving it to me way high. If I just divide by 10 I don't think that is right either since the hatch areas are very irregular.
Scale the cross section vertical down by 10 and don't change it horizontally. I don't know if this is possible.
Somehow set the horizontal and vertical scale and hatch above and under to get the areas. I don't know if this is possible either.
I have a drawing (autocad 2011) ,which i have to measure the areas of the many rooms and i arrange these areas in a table! is there any fast way to do so? avoiding the boaring typical area measurements room by room?
View 9 Replies View RelatedIs there a way to have a table that calculates cumulative hatch areas of certain layers? And if I change the layer of a hatch, the table then automatically updates?
View 2 Replies View RelatedI would like to display the room name and area as text from a spaces i have created. Like a room tag that will automatically update if the space is altered.
I have tried a number of ways but have been successful and the solutions are often overly complicated.
I have since given up and simply entered text and included a field for the space name and another field for the base area however this is quite laborious. surely there is a simpler way of doing this.
I would also like to include occupancy numbers that would also calculate the m2 per person if that is possible?
What is the difference between rooms and areas? Why create an area schedule off 'areas' as opposed to using 'room' areas? Can you create a schedule off room areas?

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.

If polygons are more complex =erroneous result from calculation ("Round ( Area2D ( Geometrie ), 0 ) "). It means ACAD calculate sum 2 areas together, but It should dedust island from main polygon.

View 9 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.

View 9 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.
