AutoCad 3D :: Applying Surface / Turning Series Of Curves Into Solid Object
Mar 23, 2012
I am currently working on a project that involves some basic collision simulation of an LNG ship in Solidworks. However, before I can do that I need to turn the ship (which at the moment exists as a series of curves, see attachment!) into a solid object, which I can then export as an IGES file.
So far I have tried the PRESSPULL command and it hasn't worked at all, only produced a "not responding message".
I would like to know how can put planar surface to solid object which surface is curved like cylinder for example. When start draw from first point rectangle of planar surface follow x cordinate not that solid object. How to do that simply?
I have a bunch of points that I am trying to turn into a solid object. I am doing this by using the 3D poly command and then LOFT, UNION and CONVTOSOLID. this has previously worked well, but this time when I use the LOFT command it does not produce a 'closed' surface, but rather a grid like surface which wont convert to a solid. Are there different settings for the LOFT command, and if so, How do I change them to produce a closed surface?
I have a copy of an old plan showing curved boundaries which I wish to recreate in C3D. There's lots of connecting arcs, all of which are annotated like:
RAD 15 CHORD 21.213 121°22'15" ARC 23.56 T.L. 15
I can see that the first line is the radius, the 2nd and 3rd lines are the length and orientation of the arc chord, the 4th line is the arc length. I've been able to get a correct result by firstly drawing the chords, then adding arcs with the appropriate radii between the two ends of each chord. However, I'm sure there's a quicker and easier way. Sometimes the arcs are separated by short sections of straight line which have length and bearing details as well.
I have finally created the shell of the complex surface that you see. This is only a section of the part because I cannot show the whole thing for proprietary reasons. I formed solid surfaces using the network command. The propblem is that it will not convert to a solid because the surface seams are not "water tight." When the network command created the solid surfaces, the surface seams do not exactly match the lines so there are gaps in all the seams. I have tried blending, patching, etc. and nothing works. how to convert this to a solid without losing the outlines and the shape?
I downloaded the .stl file from here, which is a very detailed model of 20mb size:
it can be opened in inventor and is shown as a mesh object. Then I tried the plugin "Autodesk Mesh Enabler" to turn it into a solid. After almost an hour it produced something of 350mb, but it cannot be opened anymore, it crashes inventor immediately. Are there any settings to that plugin to reduce the number of elements that it creates?
I heard Mesh4CAD is a similar tool for autocad. I am installing autocad now, hoping that it is more powerful for these kind of things...
I just need to take measurements and attach new objects to the model, or can this somehow be enabled for mesh objects as well, without converting?
How can I remove the lines in the middle after I press and pull the objects.
Attached is the Untitle.jpg, to make more clearer to you. Blue is the wall and skyblue is the aquarium. I want the back and the front of the aquarium don't have any line in the middle but even I do shade command the fill of the color is still there. Cause if I explode and delete the line in the middle the colors that fill the aquarium are getting rid off See Untitled 2.Jpg to see what I mean. And also how can make the aquarium Untitle 3.jpg transparent?
I have problems applying an Outer boundary to eliminate a small area within a big surface (and a few Hide boundaries within that Outer boundary): Civil 3D somehow creates extra triangles within my surface (that don't really make sense to me). I am applying the boundaries as non-destructive boundaries as I need the surface to extend all the way to my applied boundaries. The surface needs to be untouched (except applying a few Outer and Hide boundaries) as it is design data.
We received a surface model from a vendor that I have patched up as best I can, it still has one hole that I can find that I haven't been able to fill. Ideally we would like to have a solid model, but I'm running out of time to get this done and the surface model we have would be good enough for our purposes IF I can get the yellow surface tangent lines to turn off or change their color to black.
I've attached a jpg of the surface model with the yellow lines and uploaded the model here: [URL].....
I want to loft the surface, made of polylines.The problem is that, when I select all the splines, and then do Draw-> Modeling -> Loft then I chose the "Cross-section only", this what kind of message I get in command box:
The selected entities are not valid.
Here the .dwg file with the mentioned splines in it:
I need to create a series of "trays" that are in the shape of letters. I am having some success with certain letters, but zero success with others.
I am creating these letters using a curve brought in from illustrator, and sweeping the profile that I want to use around the curve to create the outside.I am then using presspull to create the base of the tray.
However, sometimes the sweep command will simply say "unable to sweep 1 selected object" with no explanation as to why.
Sometimes I will get the shape that I want, but it is facing the wrong way, and I cannot fix it. Other times it will simply stall and then delete both the curve and the profile.
Civil3d 2012 - is there a way to project standard autocad lines and curves to an existing surface to the lines and curves end up with the surface elevations? we are trying out that wants 3d lines exported in a dxf file. We have a surface and we have the lines...it's just that the linwork is all at 0 elevation.
Any way to evenly space contours around a curve in a surface.
Many times I have a steep area in a surface that needs to be displayed using 1 foot contour intervals, and in certain areas the contours are crossing each other around curved areas, like a curve in a ditch. In the past i have had to "fudge" the surface a little to get the contours to look correct.
Just draw a rectangle and a circle, then give them different colors. Choose AI menu "Object | Blend | Make", before this step you could set "Specified steps" to an integer in "Blend Options...", now you get a series of blended arts. Using Direct Select Tool you can select the rectangle or circle you drawed at first.
how to know if the art object you selected is one part of the blended series? I looked into the document but cannot find a proper API to get the infomation in AIArtSuite.

My question is, how to write code to know if the art object you selected is one part of the blended series? I looked into the document but cannot find a proper API to get the infomation in AIArtSuite. (for CS5 & CS6)
I am having a problem applying a planet surface texture to a geosphere.The problem occurs both with and without UVW mapping and it is the first time I have experienced it.(I'm assuming it is something that has been ticked somewhere that I cannot find)
The planet surface texture is a flat space view map. Usually when I apply images like these to spheres it perfectly wraps however this time it is confining the image to one "corner" of the sphere.
I have created a model, by lofting a shape along a curved spline path. The model properties is currently '3d Solid' what I want to do is generate a 3d Face off of this model.
I have exploded the 3d model and that gives me a surface, bu the dilemma is that I do not know how to 'trace' or turn this surface into a 3d face format. What I was thinking is that if the surface could be exploded into individual elements I would be able to draw over the surface with the 3d face tools and then have my model, but a issue with this is that I cant explode the surface into elementary elements AND the 3dface tool cant generate curves.
In short how to turn a 3D model into a 3D Face or a Surface into a 3d Face?
The program I am exporting the model into accepts the following:
DXF Entity SAP2000 Objects 1 POINT Point 2 LINE Frame/NLink 3 3DFACE Area 4 3DPOLYLINE Solid 5 CIRCLE Line(s) 6 ARC Line(s)
Note: To be able to import the dxf entities as solids in SAP2000, you must draw them in AutoCAD as meshed polygons or meshed solids. I could also export the model as a solid but again do not know how to get a meshed polygon or meshed solid from my 3d solid, when I do mesh smooth, the model basically turns into a rectangle and looses its detail.
As you can see it is number 3 I am working on. I have managed to create simple 3d faces and get them into the program but the 3dface tool is very primitive and I cant see how I would create the curves that my model has, I cant seem to form a grid system either to use the 3dface - everything seems to draw in space.
I have asked to amend a drawing, which consists of lots of square tube sections and other stuff, however I have received it in IGS format. I have got it to open in AutoCAD by first opening it in Inventor, then using the 'Save Copy As' command to save it as a DWG. However, instead of it consisting of solid tubes which I assumed it would be for me to easily amend, it's all surfaces.
I can't find a way of opening it as a solid model (maybe the file type doesn't allow it anyway), nor can I seem to convert any of the surfaces into a solid.
I have attached a sample tube from the drawing, how to turn it into a solid? I am moderately experienced at solid modelling from scratch, but I've never come across something like this before.
how to put a 3D object on top of the another 3D object in autocad"! E.g.,I want to put a 3d object of one leaf (raised 1") on top of the vase, so that the edges of the leaf are placed completely on the surface of the vase.
I extruded the leaf 1" first, then tried to copy it on a solid cylinder of a vase, but it didn't work!!! It seems to be simple, maybe not!
I'm having a problem creating a 3D Solid from two 3dpoly lines. I'm attaching a script file which reproduces the two 3dpoly lines to use for the LOFT command. As you can see when running it, I have two closed 3dpoly lines which use exactly the same X,Y coordinates and differ only in the Z axis. I'd like to make a 3D Solid with these lines, which should be possible using the LOFT command... but I only get a surface around the 'sides'.
I needed to remove the .scr extension from the file in order to attach it, so to run it you need to replace .txt with .scr at the end of the filename. It's a standard ASCII script file. If someone prefers I can also give the coordinates of the 3dpoly lines as a post.
i have recived an igs fle which i imported into auticad 2012.when imported the and saved as an .dwg the model is in surfaces, im looking to convert the surface to solid so i can export the file as an .stl for 3d printing. is it possible to convert this?
I need to slice a cylinder with a surface but the slice command keeps giving error " Inconsistent face-body relationships".
I created the surface from a solid that I created using solid intercept between the cylinder and another solid that the cylinder actually passes through (a housing I have). In my attachment I do not include the housing, just the cylinder, the solid intercept and the surface from the a face of the solid intercept.
I tried increasing the U & V isolines of the surface, and scaling it up so that it isn't bounded by the cylinder, but that didn't work.
I'm willing to try any technique that achieves the same goal - I need the butt of the cylinder to contour to the housing so that I can do a JOIN and have a solid housing with a cylinder sticking out of its face. The inside of the housing is hollow with a 0.05 inch wall.
I am working on a project and have ran into a problem. I need to hollow out a currently solid surface in order for it to have a uniform thickness of 3mm that follows the curvature of opposite side. These pictures will show what I mean.
Basically, I need to hollow out the backside to make it fit the surface of the front side with a thickness of 3mm. Is there some sort of tool that is designed for this or another way of doing it?
