AutoCad 3D :: Subtracting Surface (loft) From A Solid?
Apr 12, 2012
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."
AutoDesk 2014 . I am currently trying to design in iphone case. So I downloaded a replica iPhone from grab cad:

I imported it and formed a solid around it, now I am trying to subtract the phone from the solid so it perfectly fits within the case. It will not let me subtract it though because the phone is a reference block and the square around it is a solid.
I'm loft retarded. What I did here was loft to a tangent work plane, then did a sketch on the top surface and extruded the shape that I want. There has to be a better & easier way.
I'm making these legs for a piece of furniture. I need this to be a solid object.
So I drew a vertical line, set the radius using circunferemces. Then (can't remember how, it was long time ago) I manage to turn them into surfaces (circles, so it's an area).
Now when I loft them, it won't result in a solid. Why?
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 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?
layman what Autodesk is wanting me to change? Trying to use "loft" to skin the surface of 5 polylines. It will do the first, second, third and 5th for a surface, but doesn't like the 4th polyline I created.
I am having problems creating a profile around a path. The profile (image-1) resulted in an undesirable corner (image-2). Which I don't know if that can be fixed. My workaround was to create a lower profile, and then loft between the 2 rails.
The loft results in a twisted surface (image-3). So to correct this under loft> transition I turn off automatic mapping and edit the point set. I always end up with one extra set of points, or edge, and end up having one set of points on top of another, a duplicate edge. Which I believe is where my problem lies. However I can not delete this extra point set, so there is not much I can do there. Am I missing something? This results in a surface loft (image-4). When I thicken this surface by 6mm it results in this broken solid (image-5)
I have tried merging tangent surfaces in the loft command, which appears to work better, but when using thicken the error message reads that the thicken operation did not produce a meaningful result. When I change the thicken direction I get a solid, just not the one that I need.
I had many other strange errors, and seemed to have solved some of them by taking the fillets out the sketch, and applying them to the solid. But this should be an easy operation, and I can't seem to make this work at all.
I am using Inventor 2014 and the ipt file is attached.
Attached is an Inventor 2012 part file. I am trying to perform a surface loft with multiple sketches and rails. Each time I try to perform this operation I get the following error:
Error: The attempted loft operation had problems with the specified rail curve not intersecting one or more sections. Try repairing the rail curve so that it intersects all the sections.
I have corrected this issue as much as I know how by project the rails onto each sketchs workplane and then using the projected points to constrain the sketch. It is not working.
It is very difficult to explain, but I have attached the part file. It was created from Autodesk Inventor 2012.
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'm constructing a simple test track for my university project, and I have managed to get the geometry of the track all sorted. I'm struggling to assign a bitmap image of a 4 lane road surface to the track. When I assign the material all I get is a grey surface with no lane markings. I figured the size may be wrong, but I have tried adjusting the size settings in the co-ordinates roll out in the material editor, with no luck.
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 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'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 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 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?
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 was given a STEP file that was created in Solidwoks which when opened in Inventor 12' is a surface.
The surface can be successfully thickened after it is stitched, prior to stitching it fails due to it's complex obround, tapered, bell shape. However, because thicken only thickens perpendicular to the surface I end up with a lot of unusable ends with crazy angles and in many cases additional phantom surfaces which I cannot cut off or sketch on because they don’t really exist. Thickening has not been a serviceable option to this point.
All other techniques I try when making this model from scratch fail or do not match the original surface. Measuring the surface is difficult because the only measurements we get are the lengths of the loops, no radial measurements. Additionally, when I enter the solid I created from scratch into an assembly (whether it’s geometrically correct or not), I cannot constrain it, I can’t click on anything but the working planes – no surface, face or edge can be picked on the solid itself.
Making surfaces into workable solids? Is there anything I should do different? Is the sequence I am using incorrect? Correct order of operations they use to successfully create a solid from a surface?
Any program to convert 3D solids to a mid plane surfaces? We need our models in this form to do FEA work on them. I wanted to ask this question before I took on the task of trying to create one myself.
I am trying to convert this composite surface into a single solid body, however when I try to stich the surfaces in the construction environment it always crashes. I have also tried edditing the STEP file import options but it still always opens as a composite surface.
