AutoCad 3D :: Intersections Of 2 Arcs?

Jul 25, 2012

1st let me preface this with the fact that I know zilch, nada, nil about solid modeling. But I think the easiest way to accomplish what I'm trying to do is thru solid modeling and export the end result as (3D) polyline

What I have is 2 intersecting arcs with varying radii and ucs values. I'm guessing these could turned into regions and then subtract 1 from the other in order to find a list of intersecting points or maybe a splined pline. Or maybe they could be joined. Either way, if I DXFOUT the solids in R12 format, they become plines

I have access to R14 thru 2012

AutoCAD Civil 3D :: Intersections As Separate Corridors

Sep 26, 2012

What is the advantage of creating a seperate corridor for an intersection? Doing so requires leaving gaps in the road corridors at the intersections which creates a mess in the surface triangulation through the gap. I know we can clean it up by creating a composite surface and pasting all the pieces together but how tediious that is!

I was wanting to keep the intersections as seperate corridors because if we add them to the road corridor we end up with numerous duplicate baselines which makes editing and data management a nightmare.This whole process is a huge time consumer. I can't understand how Autodesk expects DOT's to adopt this software with this workflow.

AutoCAD Inventor :: Dimensioning To 2 Implied Intersections

Aug 22, 2012

I have run across a situation that I have not been able to find having been previously asked. I have attached the file of what I am working on.

I have 2 dimensions to the implied intersection, but how do I put the dimension when there are 2 implied intersections? Such as along the bottom of the part.

AutoCAD Civil 3D :: Corridors Surfaces And Intersections

Mar 7, 2013

I've created a T intersection and have created the surface for the T corridor and the entering side road. The surfaces appear correct. When I create a surface for the main road, which has been split into two regions, the surface goes thru the T corridor. How do I create a surface that simply goes up to the T intersection and picks up again after the T intersection?

AutoCAD 2013 :: Divide Big Region On Lines Intersections

Oct 1, 2013

I need to divide a big region on lines intersections. imagine that you create a region around a chess table and break the region so you get each square as a new region.

I can't use array because the sub-regions aren't regular. I need this divided regions to export a DXF file to a Finite elements program.

AutoCAD LT :: Command That Would Break Lines At Intersections Automatically?

Apr 4, 2012

Is there a command that would break lines at intersections automatically? 

I know there is such a command in autocad map 3D, but is there a way to do it in LT?  With a macro?

I have attached a picture of the parcels that I like to break at each intersection has an example. 

Then I go on to use the OVERKILL command which works very well.

AutoCAD Civil 3D :: How To Make Copies Of Intersections Or At Least Simple Intersection

Mar 24, 2013

We are making road , it has intersections with simple roads wich leads to forest or a fields or to a private territory. We have 60 of those intersections (crossroads) , if we would start making them all with intersection wizzard it would take a lot of time... , maybe there is simpler way to make such an easy crossings ? ( all of those crossroads are same type same geometry, the only difference is location)

AutoCAD Civil 3D :: Adjusting Intersections Secondary Road Profile

Jul 9, 2013

I went forward designing intersection profiles with limited survey and simply made an educated guess for the secondary roads pgl tie in point. I have received updated survey and when I move the profile end point to meet existing grade it adds another pvi effectively holding the profile grade I set preliminarily. I'm keeping the lock point. Is there something with the return/ offset profiles preventing this edit? What is the proper work flow?

AutoCAD Civil 3D :: Labeling Alignment Intersections In Production Sheets?

Sep 5, 2012

Using the Best Practices, different components in their own DWG files, all brought together in a production sheet where I can place the labeling for that sheet. I can add labels for Surfaces, Alignments, Pipe networks, through the Xref(s). Evidently this was not extended to Intersection Objects.

What I'm doing now is creating a new Intersection at each street intersection just so I can get a label which shows the station of each alignment at the intersection. Is there a better way to do this?

AutoCAD Civil 3D :: Intersections 2010 - Change Curb Return Radius

Feb 24, 2012

Changing the curb return radius after the intersection has been created. I am able to go back to the curb return parameters dialog and enter a different value, but once I hit Enter or OK the value reverts back to the one I orginally used.

So it looks like I have to delete the intersection object and re-start the wizard from scratch.  Not that it's a big deal, just thought there might be a way to make the change once the intersection is built.

AutoCAD Civil 3D :: View - Visualization Of Corridors With Multiple Baselines Or Intersections

Aug 28, 2012

I created a simple roundabout in Civil3D with the intent on visualizing the corridor in 3DS Max Design using the Civil View plugin. The corridor rendered complete in Civil 3D, but there are large corridor gaps in Civil View. They all appear to be at the location of corridor baseline boundaries. Obviously this is a non-starter, as 3DS Max is supposed to improve the visual quality, not reduce.

Attached are some sample images of the roundabout in Civil3D and in 3DS Max Design.

I am using Civil 3D 2012 and 3DS Max Design 2012.

AutoCAD Visual LISP / AutoLISP :: Divide Big Region On Lines Intersections

Oct 2, 2013

I need a easy way to create a lot of small regions, or divide a big region in lines intersections, or a fast way to pick points inside objects.

Its like that:

imagine that you do 100 horizontal lines and then 100 vertical lines.  Now you have 10.000 squares. i need a fast way to make a region in each one of then.

So its too much trouble to pick points inside each one of then. i need to divide a big region or a fast way to create Plines or objects with the little squares. And i cant use array because they aren t regular squares.

Its something that i do often, its not a one time thing. This is necessary in structure analysis modeling, i export this dwg to a dxf file, that i use on a finite element program.

i never did a lisp before.

AutoCAD Civil 3D :: Shortcut / Routine Required To Create Multiple Surface Intersections At Once

Jul 2, 2012

I am doing bulk earthworks with C3D 2013 and quite often I am modeling large dam walls with multiple raises, core sections, filter layers, etc so I end up with up to 50 surface models in one drawing. The process I follow involves modeling each raise of the wall by targeting an elevation 10 metres or so below NSL. I then use a volume surface to give me the intersecting boundary between the topography surface and the wall raise surface. I repeat this process for each raise/core/filter section - create volume surface to find intersection, extract boundary of intersecting volume surface, add boundary to wall raise surface, put both on a unique layer calculate volume - repeat for next wall raise - ad nauseum.

To speed things up a previous draftsperson created a shortcut button on the ribbon that does the volume surface trick with one click so all i need to do is hit the button, select topo, select wall raise and it gives me the volume surface between the two, all i need to do is extract the border and add it as an outer boundary to the wall raise. I would like to take this to the next level if possible and this is where I an stuck.

If my drawing consisted of a topography surface and "X" number of wall raise surfaces all named in a uniform fashion ascending numerically or alphabetically would it be possible to write a routine/shortcut button that did the following;

1.) Create a volume surface between topo & wall surface 1 - extract border as polyline - add polyline as outer     boundary to wall surface 1 - move both wall surface 1 and newly created boundary polyline to unique layer.

2.) Repeat process for topo and wall surface 2

3.) Repeat process for topo and wall surface 3

.....and so on until all wall surfaces have had volume surfaces created between them and the topo?

AutoCAD Civil 3D :: Corridors Surfaces And Intersections - Move Each Curve And Tangent Separately

Mar 16, 2012

Heres the issue;

I created my main corridor which is a 4 lane arterial with ditching on both sides targeted to my prelim surface. On my main corridor i have several intersections and approaches which i created intersections for and set the targets so they are correct, i also created secondary roads for all intersections. Now that it is visually correct there is a few things i would like to do.

1) Combine all intersections to my main corridor and create surface for adjusted volumes.
2) Raise combined corridor and intersections to adjust cuts / fills so that all attached intersection and adjacent corridors adjust with the main corridor.

Do i have to go to my main corridor profile and move each curve and tangent separately, then check all other profiles and intersection to insure everything has been adjusted?

AutoCAD LT :: Arcs That Don't Arc

Apr 25, 2013

we used AutoCad LT 98 & hasn't changed when opening the same files in LT 2014.  All curved lines (arcs) that occur in a recently-opened file look like two straight lines with an angle at the mid-point, so that from a distance they still resemble an arc but not at all when zoomed in.  When clicking on the control points, it goes to looking like a proper arc, but the change doesn't hold after the file is saved and reopened. Is there a program-wide setting to change, or do the properties of each arc need to be changed individually?

AutoCAD Map 3D :: Text And Arcs Not To Scale

Jul 9, 2013

Using AutoCAD Map 3D 2012 Im exporting a few subdivisions to MapInfo after doing my steps on a MAPEXPORT command to create a .TAB or .MIF / .MID which are the steps do below.

 MAPEXPORT --> select format_ .TAB or .MIF ---> select my drawing manually  ----> do my coordinate conversion -----> DONE..

 When in MAPINFO and ready to open / import the exported .TAB it opens and places the drawings (subdivisions) in its correct coordinate I gave it, but the TEXT and ARC / CIRCLES do not come in to scale at all they are extremely large to a point where they can't be seen till I do a zoom all.

AutoCAD .NET :: Convert Arcs To Polylines?

I've got ObjectIds of a bunch of arcs that I need to convert to polylines for further processing.

I was thinking of using the COM interface and sending the PEDIT command and converting the arcs.

The only problem is I don't know of a way to put the objectids into a selection set, then call the pedit command and use the previous selection.
