AutoCad 3D :: 3D Faces Or Surface To 3D Solid Model?
Sep 17, 2013
I have a model of a boat from some database. It's build from 3D faces but I would like to make it a 3D solid with a thickness of 3mm.
I can convert the faces into a surface, but i can't seem to get any of the two models into a 3D solid. I have tried thicken, convtosolid and a lot of other options without luck.
I was wondering if I could make two surfaces, one smaller than the other, place them ontop of eachother and create solid between them?

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 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?

My problem today is that I made a Model of a Part of a ship using surfaces rather than solids because the engineer thought it would be easier to bring into ANSYS program for analysis but he is now having a problem with it and I am looking into converting my current model to solid. I can do it but the method I thought of using is quite long winded and we are working to a tight deadline.
1.open up the surface part
2.use "Offset/Thicken"
3.any clashes between parts make a sketch and cut away.
the problem is the amount of plates I have and the time it takes to sort them out.

I am trying to find a way to import a laser scanned mesh or point cloud file into Inventor (2013) such that I can use it to make a parametric representation of the form. The import format can be STL, OBJ, VRML, XYZ or PLY. I have tried the Mesh Enabler from Autodesk Labs but the files I am looking to work-on are bigger than the enabler can cope with and my system slows right down or locks-up.
I know bespoke reverse engineering software is the ideal way to go but I was hoping there was a way to model over a mesh to represent its form to create a placeholder in a parametric assembly. I'm not looking for accuracy, just a surface or solid output that can be constrained to native inventor parts. If I could get the files to STEP or IGES someway that would be enough.

I'm trying to work with some geometry imported from another software. Somewhere there's a problem with drawing precision and imported geometry gets slightly warped. For example in the attached file four points of bottom face should be in the same plane, but they're out by 0.0006mm (in this case). Similar imprecision is evident on all sides (this should be a kind of a flat panel-type object with grooves cut on sides). Is there a way to get autocad to merge faces on a solid or somehow clean it up?

I have been tasked with making a feature/hole chart for a complex cast & machined part.
What the quality engineers want is color-coding of the actual features to denote which machining operation they are cut in. It's intended to be a quick reference for the machine operators to identify if there has been a missed operation, broken tool, etc...
What I have done in the past with simpler parts is import the .stp file, then FLATSHOT each of the views. I HATCH (solid) the boundary of the machined feature, then add the hatch pattern to a layer for the appropriate OP number. Callouts are added to the layout in paper space, and it's released for issue.
The problem with the new parts that I am working with is that they are MUCH more complex than the others I have done (50-60 machined features, complex compound shapes and curves, etc...), so using FLATSHOT results in many, many broken boundaries and edges. This has made editing them to get HATCH to work exponentially more tedious and time consuming.
I've tried to hatch by picking internal points rather than by manually selecting boundaries, but it takes 5-10 minutes for my machine to finish "analyzing the selected data" and almost universally fails to generate a hatch. When it does work, the hatch is incomplete, due to curves and angles in the machined surface.
The above method does work, but it's causing me to neglect other projects due to the time required. Any (comparatively) simple/easy way to accomplish this directly on the 3d solid of the part to speed things up.
I am using Inventor suite 2008, but I am not well versed with Inventor or the 3d capabilities of AutoCAD. I use Mechanical Desktop 2008 for the majority of my CAD work.

I have a problem with getting an Inventor model into Revit. It's not the import of the model that's the problem, but the way the model displays in Revit. (It displays fine in AutoCAD, 3ds max etc - just not Revit.)
Here's the part file - it's just a simple box with a couple of split-face features on it to generate a pattern.
If I take the model into Revit, I can only see the pattern if I select the object.
Deselect the object and the pattern vanishes. Here's an unselected/selected screenshot from Revit:
Models attached - Inventor 2014 IPT and a SAT version of the same.

I've currently written an application for SolidWorks that reads file that geometry in the form of faces (ie. 3 or 4 double values that represent triangular and quadirilateral faces). I am trying to create the same application to work for Autodesk Inventor, but I am having some issues.
First, I am basing my code off from the examples given in the help files. There's a lot of pointers to objects being to get to the Face creation portion, this seems to be slowing my appliation down considerable compared to the SolidWorks counterpart. SolidWorks API has a modelling method called CreatePlanarSurfaceDLL that allows me to provide an array of doubles representing the vertex points in order (x, y, Z) for each point, so the array looks like this for a triangle (P1.X, P1.Y, P1.Z, P2.X, P2.Y, P2.Z, P3.X, P3.Y, P3.Z). Is there anything similar in the Inventor API to simply the process?
Secondly, when using the example, they all have a known "shape" and therefor there are a definied number of vertices, edges, faces, etc. And when adding the faces, the known points / vertices are used. In my case, each face contains information for it's 3 or 4 vertices. I created these using the prescribed methods, but when the final surface body feature is created, and a repair is performed on it, it shows a lot of duplicate edges and vertices. Do I need to take the time and filter out all of the duplicate vertices, and point to a single vertex that may represent a vertext used by up to 3 or 4 faces?

I have created a TIN (triangulated irregular network) of an existing survey in my terrain modelling software (12d Model). I am able to export (save-as) the TIN as 3D Face Triangles for opening in AutoCAD (2012) or similar.
My ultimate goal is to create a solid surface in Inventor. The surface has to be seemless (stitched) in order for me to create a new sketch and extrude to this surface. Finally giving me a part in Inventor that represents my ground. I would then want to use the same process to bring into Inventor all other Civil Design works created in 12d Model such as roads, earthworks platforms (including dams) etc.
I've tried stitching (Inventor and Microstation) without success. Inventor keeps crashing and Microstation looses data. AutoCAD (2012) won't let me create a polyface mesh from 3D Faces. I tried doing a mesh, surface union without success. Programs either crash or data is lost.

I am fairly new to 3ds Max and I would like to know if there is a way to fix my model to get rid of the triangles within the faces. And how I may prevent these errors in the future.

I would like to edit the faces of a model I imported into Maya, but I cannot find the face option when I right click. When I create a polygon however, it works just fine on it. Is there any way I can convert the model into a polygon?

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.

I am trying to model I-Beams to s solid. I put 3d polyline around the front "I" then a path down the middle of the beam. I have tried extrude, sweep with aligned to path, and sweep not aligned - then put a patch on both ends. Use the command "surfsculpt" and it will not convert due to not being water tight. I delete the 3d poly and path line before patching.
We only have 2011 - Civil 3D.

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'm using ACAD 2014 Win8 64bit.
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 have a scanned model of a casting. It was necessary to delete surfaces to remove the casting flash from the model.
I have lofted/patched/stitched the missing surfaces to close the solid. Apparently there is a gap somewhere because the model remains as a surface instead of returning to a solid.
How can missing surfaces be found in the model?
What else can prevent the model from returning to a solid?
When stitching, the gap tolerance was set to .002". The model will "rebuild" without any error messages.

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.
Top Side:
Bottom Side:
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?

I have created a surface in Civil 3D by adding contours....... Now that I have created the surface I need to Exoprt it to .sat / .stl files. But in order to do this I need a 3D Solid.
How do I convert this service to a 3D solid in order to the the export?
I have tried the thickening option in the 3D Modeling workspace but it doesn't want to accept my surface.

I'm having trouble trying to place a material onto a surface so that it aligns with the x-y coordinates. When I use drag and drop from the materials library and use ctrl to select one particular surface/face, the material drop s in fairly arbitrary.
I thought I could use materialmap to force it into a particular alignment and while I can use the commands to set the base point and alignment, the material does not update with the boxed alignment.

I have a solid that was created by extruding a regioned profile. I have made a lofted item (Yellow), that I will have to subtract from the solid (Green) to create a hole. When using the subtract command, I recieve the following error.
"The selected surface was ignored. Surfaces cannot be subtracted from solids or regions. At least two solids, surfaces, or coplanar regions must be selected."
I have tried convtosolid as well & to no avail.
