I have 2 polyline. First I need to know whether those 2 polyline intersect with each other or not. If they are I need to change one of the polyline shape deduct the intersection area.
How can I do that?
is there a way to extract a 3D poly line where two surfaces intersect each other.
i have ground surface and i have dam surface. they would like to show the filler material in the cross section graph.. so i copied then raised the surface the required depth.
so now the surface and side slope of the dam intersect. and i would like to trim the filler material surface to be in line with the dam.
I'm using CS6 and I can't figure how to Intersect Shape Areas. The website I'm using is saying to use the pathfinder panel which I can't seem to find either.

View 8 Replies View RelatedI have been sent a client's construction drawing for a care home where i need to design the sprinkler installation. The majority of the rooms have got the same head positions within them, but they have all got a slightly different angle as the building is shaped like a banana. Unfortunately its not a uniform radius that i can tell as the one side is larger than the other.
So my question is this. Normally, on a square building, I drop in construction lines along the bedrooms so that i know my sprinkler heads are all the same distance off a wall, and I only need to line up one side. However, with this building being a curve, and the wall angle being slightly different on each room, how do I place an angled construction line or polyline to act as my set out line for my heads.
Any routine that would allow you to cut out an odd shape from a solid with the profile of a polyline?The goal would be to have all the pieces that are left, not subtract them out..

I know how to get the coordinates but I need to get and change one of the coordinate.
how to change the elevation of each vertex on a polyline so that each vertex has a different value. The way I attempted this in the past was to click on polyline, click properties and give each vertex the required elevation. However when I looked back at the values I noticed that every vertex had the same value as the last elevation value entered. is it something to do with ensuring polyline is 3D?
View 2 Replies View RelatedI need to draw a polyline (or spline) in the XY-plane, followed by a vertical segment before continuing in the XY-plane again. The challenge is working out the vertical part while still in the top view. There's no way to change its elevation on the fly that I know of.
View 2 Replies View RelatedI am using acad 2010. I have a contour generator that uses 3d polylines to make contours. I get depressions or tops where I don't want them. I need a lisp routine that will allow me to adjust the z value only on any 3d polyline. I need to raise or lower the z value at any vertex and repeat if necessary. I don't need to prompt the user- I am the user.

View 4 Replies View RelatedI want to make a block with dynamic attributes. Basically I have some polylines on my drawing which represent cables, and I want to have a block with a legend on each polyline with 2 values. First will be the cable type which I would enter manually and the second value will be the length of the polyline. Is there any way that the block would read the length of the polyline and dynamically change the 2nd value?

I have a bolt program that draws the thickness of a bolts in elevation as a polyline with a global width, what i need is a lisp to then change this lwpolyline to a hatch, ie if global width is 20 and the polyline is 30 long i need to change this to a 20x30 solid hatch, is it possible to get the the global width and length and convert this to a boundary hatch? I need the same thing done for bolts in plan too as the circle is a lwpolyline also.

View 4 Replies View RelatedDue to modeling purposes, I need to convert a 3D polyline to a spline. What I have been doing is:
- change polyline fit/smooth to cubic from properties
- convert polyline to spline by typing spline -> object
- method -> fit from properties
You can see the original 3D polyline (green) and the resulting spline (magenta) in the attached drawing.When I zoom in and measure the distance between the two entities at different points along them, at some points the perpendicular distance exceeds 5 millimeters, and I want to ensure the deviation remains under 1 millimeter or even less.
I know I can change the knot parameterization of the spline, and this does work at some locations, but the difference increases at others.Why is there a 5.6 mm difference between the spline fit point and 3D polyline vertex, as measure in the attached drawing?
Now, I can go and manually stretch the fit point to coincide with the vertex. Also, I can add fit points between existing ones to drag the spline closer to the original 3D poly.
However, some of my polys are really long, and it is very time-consuming to do this manually while measuring points along the entities to make sure the distance stays small enough.
how to automate this process? For example a lisp that would maybe take the original vertex points, add say maybe 3 (not too many) new ones between them, and then generate a spline while making sure the deviation is less than the set value of 1mm? I am using AutoCAD 2013.
I've been working on a custom polyline object, and I've got it functioning!!Having said that, I plan to run its creation around picking a point for bounary selection.
(Other than trying to step through every vertecies) is there a technique I can thow the polyline data from a traceboundary result into my custom object? I've been trying to add the polyline from traceboundary to my object BEFORE it's added to the transaction by the way...I assume that's right, since I want to put it's data in my custom object then add my custom object to the transaction instead.

Is there a way to make one viewport supersede another so that say parts of the first viewport dont cross over into the second (not enough room). I have one intial viewport. Then four other viewports which are scaled in portions of the inital. I want the scaled in viewports to supercede images from the initial so that there are not parts of the intial intersecting into the "zoomed" in viewport pictures.
View 9 Replies View RelatedAny way I can align a new polyline to a reference polyline (orig polyline).
The 2 polys will be generally the same length, however, the number of vertices will differ.
Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.
How do you find 'if' a polyline is inside another polyline?

I have two ~parallel feature lines about 250' apart. I grade the Easterly Ft Line going west at a +1.5%, and I grade the Westerly Ft Line going east at a -2.00:1 slope.
I know C3D doesnt have a tool to intersect them, I must use the intermediate surface approach.
What I did was grade one, create 'Paste Surface 1' then grade the other, create 'Paste Surface 2' and then I created Surface 3 and pasted 'Paste Surface 1' and 'Paste Surface 2' into Surface 3.
Throughout I used 'Grade to Distance'
Surface 3 doesn't come out correctly.

I am wondering if there is a function that takes two lines that are not parrallel and will extend them until they intersect?
View 9 Replies View RelatedI am running into an issue when two viewports intersect. Typically the drawing is just a standard single viewport but I have a certain couple instances (drawings for a special part of the report) where I have made smaller viewports that overlap with the larger. Where they overlap as most know you can see the objects from the underneath viewport in the overlapping. I had been described a technique of clipping it away but being that this is only used in few circumstances I was looking to operate this more of a "Toggle" like option. I have assigned the "Viewport Frames" on a seperate layer in which can be toggled "ON" and "OFF" using the MVIEW on the frames to apply or unapply the viewports. But when I toggle off the viewports the clipping has removed the portions of the underneath viewport (as it should). Any way to tell AutoCAD that when two viewports intersect the top one is not transparent of whats underneath??
