AutoCad 3D :: Create A Solid Which Is Of Wedge Shaped
Apr 14, 2013
I am using AutoCAD R14. I need to create a solid which is sort of wedge shaped. But the top surface twists (like a propeller blade). So it is not in any one plane. Also, that surface is not square (no right angles). The bottom surface is flat and in the x-y plane. It is a quadrilateral. The other three sides are a rectangular flat surface and two triangular flat surfaces.
I don't know how to create this shape as a solid. I was able to create several polylines to accurately describe the shape but then when I tried to join them together to create a solid using the UNION command I get the following error message: "At least two solids or coplanar regions must be selected." How can I create this solid?

I need to create a 3D model of a segment of a jogging path/trail that has a drainage feature called a knick. I pasted a freehand drawing of what a knick looks like below this post. It's a semi-circular area that slopes to one side at a small angle on a trail that is otherwise flat. I need a model of a trail segment with two of these sloping indentations that is just a smooth, gray object- nothing fancy. I managed to create a simple 3D model for a second trail design that has a slope to one side throughout the trail- made a box with a tapered edge and rendered it gray.
Since to my eye a knick looks like a lemon wedge indented into the face of a box- that's what I've been working towards. Made a box, made a cylinder, moved the cylinder so half of its base sits on top of the box face on which I want the indentation, and then used pushpull and subtract to take out a shallow semi-circular cut off the top of the box (did two of these about 20 units apart on the same face).
I don't know how to taper the semicircular cut so that it actually slopes off the face to the edge and doesn't look like a clean cut depression. I need it to slope to the edge at a 2% angle. I've tried tapering many times, but I don't think I completely understand the concept of the tapering axis because all I end up doing is tapering the various faces of the box and the knick cut stays the same. I also tried out all the tools on the ribbon that look like they can be used for filling in or smoothing edges, but without any luck. Should I be approaching the process of making the knick from a completely different set of commands?

I tried every single way to try to extend the with of the hole body but it's not working in any way The problem is its a solid body which looks like a rectangle shape frame,and i made it as a hole union which i cant simply extend the top and the bottom widths.

Most engravings into solids are done in real life with a V shaped engraving bit along a text outline. Having come from a very dated Inventor 7, I was hoping my new Inventor Professional 2012 edition would be able to tackle this with ease. I thought the embossing of text would provide what was needed, but the emboss feature only seems to engrave the solid of the text and not an outline of text. With no luck there, I decided to import an AutoCAD text outline onto the surface of my model and try to sweep the tool shape over the path. I’ve been successful only with text that is composed of straight lines. Any text shape with an arc or line segments is frustrating me like crazy.
I’ve attached a file showing my successful engraving over some letters of the text. This is my desired output.When trying to sweep the tool path along the “R” in the model, an error comes up saying: The attempted operation resulted in the creation of a self-intersecting surface. Try with different inputs.
When trying to sweep the tool path along the “C” in the model, it actually displays a preview of the end result; however, a different error comes up saying: The attempted operation had problems trimming and discarding faces. Try with different inputs.

i'm trying to create a custom shaped viewport. Instead of using just a rectangular viewport I need to make it polygon shaped. I know I've done it before but for the life of me I cannot remember how. I'm using ACAD MEP 2011.

I cannot figure out how to create a flexible T-shaped dynamic block. It falls apart scattering the linework all over the screen. My constrain parameters for width, height and thickness are not controlling the lines. I have an I-beam shape that works, but using that to make a Tee didn't work. Or a link as to creating semi-complex dynamic blocks.

I'm trying to create a hole in a sheet-metal part so that a pipe can be welded in it, see attached picture. What's the best method to do this? Because the flat-pattern of this hole isn't an ellipse-shape (more like an egg), it seems it's very difficult to do.

I would like to learn how to create a pizza slice shaped graphic similar to the one attached. Preferably in layers so that I can change the individual photos easily. Pizza segments must have rounded corners and be equal proportions. Individual images have a thick white border and gray stroke.

Today's challenge was to create an artificial reflection beneath an irregularly shaped object.
In the past I've been asked to add reflections where the reflection is simply a plane that cuts horizontally across the entire object (example 1), and where the object to be reflected is skewed (example 2) - both operations are pretty straight forward...
Example 3 is the object (a duvet) to which I had to add a floor reflection. I did come up with a solution, which I am reasonably happy with, but would love to see what methods other people use! I guess my attempt is OK because the texture and shape of the duvet is fairly forgiving!
Do you have a better method for these irregular floor reflections?
Example 4 is perhaps the trickiest I can imagine as the entire object is curved and the texture uniform so a bodge job will be very obvious!
Perhaps this can't easily be done in Xara - I imagine it could be painted in a bitmap package or rendered with a 3d package... or photographed with a reflection in the first place!
Xara file here -> IrregularReflecions.xar

It's a simple "wedge" assembly where the wedge is constrained to a single axis with a return spring keeping it biased one way. The are two blocks that are pulled tight against the taper of the wedge with springs that keep them pressed against the taper. When the wedge moves in they split, when it moves out, they contract. Simple, right?
For the life of me, I can't seem to constrain the parts correctly to the taper so it behaves correctly. The design is proprietary, so I've made up a "lite" version of it and attached it here.

I have an assignment. I've done all the work until i reached the end of it which is adding 2 cylinders to a weird looking object.
I'm trying to put the cylinder which shares a space between a wedge and a region but I'm unable to subtract it.

I'm working on a UDK level for a college assignment.
I want to create a circular shaped elevator with a circular fence around it that's roughly half the size of an average sized character standing on it. I then wish it import this as a static mesh into UDK.
Here are 2 sketched up designs of the elevator, what I want to create.
1st image: [URL]....
2nd image: [URL]....
I am very new to 3DS Max so I would prefer a list of steps to follow to create this elevator with a a fence,

I have a post that can only move up and down and I want to be able to drive an angled wedge sideways under it and back again, such that the post is progressively lifted by the wedge as it moves further under the post and then goes down again. How do I link this? I tried creating a path that coincides with the angle of the wedge and linking the post to that with it set to only inherit movement on the vertical, but that doesn't work. I will also need to do this with a wedge that has a wavy leading edge so that the movement of the post up and down is not linear, but follows the shape of the wave.
Perhaps another analogy would be to have a car drive over a hilly terrain, but instead of the car moving, the terrain is moving sideways under the car, which stays in the same position but moves up and down with the terrain (and the car's orientation is always horizontal (i.e. doesn't pitch its nose up and down).

As part of a larger job we have surveyed the top of a dry stone wall. The client now wants that we make a solid for him from the surveyed points with a height of 2000mm (the drawing units are in millimetres).
A 3d polyline was created from the lines joining the points and I have that in the attached drawing.
I'm not looking for someone to create the wall, but I'm looking for the method to do it, as it will certainly crop up again with this new client. I've tried many ways in both AutoCAD and Civil 3D but just can't create the solid.

I drew a 30 degree wedge with rounded short side. Where the long sides meet at the acute angle, a sharp point forms. When I join three of these next to each other, I get a three-pointed overlap at the acute point instead of a smooth 90 degree turn. How do I eliminate the acute points? I am not able to control this using the handles--or I haven't figured it out yet.

I try to migrate our ObjectArx Api to Inventor. Therefore I need a function to create a mesh from a solid.
With Autocad .Net Api, I can use GetObjectMesh(DbObject obj, MeshFaceterData parameter). Does in the Inventor Api a similar function exist?
In the parameters I need to set the deviation in the same way as in the Autocad .Net Api.
Example:
FaceterDevNormal = 0.1;
FaceterDevSurface = 0.1;
FaceterMeshType = 2;

Using AutoCAD 2014 I'm trying to model the tummy cut on the back of a guitar similar to this:
2013-06-03_15-46-23_140_zps0a2815e5.jpg
I've modeled it to my liking using a mesh surface, how can I "subtract" this area from my 3d solid body? I also have Fusion360, but don't really know how to use it.

I have borehole data of a site, where I want to sort of extrapolate the borehole data to the whole site, so that I can have a 3D soil model of the whole site. I have attached my DWG file, the vertical lines represent the borehole data and different colors represent different types of soil.
I'm thinking of manually extrapolating the data to the edges of the site, then split the site area into few different parts, and then create solids for each part, where each point is a vertices of a solid. But how to create a solid from 8 vertices, which would naturally form a closed solid like a box.
Besides this, are there any other methods of achieving what i want (3D soil model from borehole data)?

I have just downloaded an educational version of Inventor. Although I can create sketches I cannot extrude the sketch to form a solid. The origin arrow heads appear over size and it seems as if the origin plane is being extruded to form a solid!

create a plane and mirror a solid?
I am planning to have the following workflow:
Plane creation:
Through the z-axis and at an angle of 7,5° to the XZ-Plane
Naming the plane - Mirror Plane
Turning off the plane visibility
Mirror solid:
Add mirrored solid to the existing solid
Here is a sample ao the code...
Dim oDoc As PartDocument
oDoc = ThisApplication.ActiveDocument
Dim oCol As ObjectCollection
oCol = ThisApplication.TransientObjects.CreateObjectCollection
'This does not work...
oCol.Add(oDoc.ComponentDefinition.SurfaceBodies(1))
'Here I want to create a new plane
Dim oPlane As WorkPlane
oPlane = oDoc.ComponentDefinition.WorkPlanes(1)
Dim oMirror As MirrorFeature
oMirror = oDoc.ComponentDefinition.Features.MirrorFeatures.Add(oCol, oPlane, False, kOptimizedCompute)
I have also attached a simplified part file where the code has been copied inti the iLogic browser

If you can create a solid by lofting between two section, in this case they are 3d polylines, along a given path. The path is at the top of the sections. Using the loft command I have to key in the PO ( point ) option several times to get the path option to show then when I select the path it gets treated as another section. See attached.
