AutoCad 3D :: Create 3D Model Of Segment Of Jogging Path / Trail
Jul 17, 2013
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).
Here is where I ran into my own limitations. 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 (or rather I know that I completely misunderstand it) 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. Or should I be approaching the process of making the knick from a completely different set of commands?
Usually in the previous versions of maya I used the timewarp in conjunction to motiontrail for retiming my animations. In maya 2012 seems no longer work.
When I apply the motion trail to my object that has changed with timeWarp, the keyframes are displayed by Motiontrail as if there was the timewarp.
In the old motionTrail there was also a chance to see every single frame of animation with a number, not only keyframes.
Can I somehow smooth create editable motion trail curve? And why it is often that undo not working correctly, it is not updating in viewport and also if I left click and check show in and out tangent's they are not showing.
or is there a way of locking the angle of the bezier handles, when adjusting curves with direct selection tool?
Before the recent update, you could use the direct selection tool to select a curved path between two anchor points, and drag in either direction to tighten or relax the curve with the handles sticking to their current angles, the handles would just extend or shorten depending on the direction you dragged the path. It would only effect the curve selected, and would not effect the handles on the other side of the anchor point.
Since the update when using the direct selection tool to adjust curves the handles rotate, and can also effect the handle on the other side of the anchor point, if the handles/anchor point is set to smooth. Or if the handle/anchor point is set to be a corner it can create or leave sharp corners.
I'm trying to copy sheets from one dwg file to another in Inventor 2010. I get the error: "Named segment already exists: cannot create or rename". The sheet name is not listed in the target file. Why this error is occurring and how to fix it?

I would like to know how to draw segment elbow 90 degrees ( segments are not equal ) and create Flat Pattern for each of the segments - using sheetmetal in Autodesk Inventor?
Actually, I have more than 6 years experience on Catia V5 customization and vb and vb.net catia API's. What I am trying to do know is converting some applications or programs running on catia to the inventor.
The first program deal with the inventor API relating to the SweepFeatures class. So my first problem is about to find the right way to use the sketch3D for the creation of the path which is the input of the sweep method.
I know That is possible to create a path by using the CreatePath method when the input is SketchLines or any guide curve in the 2D Plan. Also, I tried to generate path by using the ProfilePath3D method of the sketch3D class but No way, the AddUsingPath method of the SweepFeatures Class doesn't accept it as path Input.
So I cannot imagine that is limitation of inventor because it was possible to do it by using the seep function of the model tab in the ipart document. How to create the path object as an input of the AddUsingPath method of the SweepFeatures class.
how to create a segmented circle as shown in the attached image. I have it as a jpg but I want to create it in Illustrator so I can have greater control over the parts. For example, while the image shows three segments, I may have to add another one into the image (it's part of a process demo).
Using pen tool I have to press Alt + click again at the node while drawing to create a cusp node.
My method is - Select Pen tool - left click for first node and drag to achieve desired curved segment - release mouse button - press again left click for second node at desired position and drag control handle to create desired curve - then Alt click at second node for cusp node - continue in this fashion for rest of the curved segments as shown in my example.
Is it possible to draw and edit control points for a cusp, smooth or symmetric node simultaneously in a single stretch while drawing curved segments with some other shortkey combinations but without pressing again S for smooth/symmetric or Alt click node for a cusp or F10 for edit later?
I have some negative space I created(black area, see first image) that I want to fill with type, not just a simple fill.
Basically I want to create the negative space from a bunch of small minus signs(-) that need to line up as they go across. If I type on each path one at a time as the text doesn't line up that way. This needs to be one continuous path. (see second image)
Unfortunately if I add them together, it creates a compound path, which you cannot type on, unless I am mistaken? So I need them to be a path, not a compound object.
I want to be able to transpose the perspective of the existing image to my new 3D prism shape.Why can't I create a path.. and then drag nodes on that path.. and warp the pixels at the same time???
It shouldn't apply to just 3d.. because I should be able to draw a rigid path around anything and warp / stretch the image from those points.
I've been trying to model cut produced by a ball end mill taking an arbitrary 3D path. I know how to do this for 2D paths (and this has been discussed a couple of times on this forum), but I have had little to no success extending this to paths in 3D. I've attached an Inventor file that demonstrates what I want to do, it has an sketch that describes the tip of the end mill and the path that I want the center of the tip to trace out.
This seems like something that should be possible using sweep feature, but if it is then I have not found a way to get this to work. The issue is that I have not been able to effectively control the angle of the sweep plane with respect to the path. In reality, the normal of the plane should be equal to the tangent of the path with the z-component zeroed out.
However, if I sweep using the path and the "Path orientation" then it does not zero out the z-component, if I sweep using the path and the "Parallel orientation" it does not take the x&y tangent components, if I sweep using a guide rail or guide surfaces it also does not zero out the z-component.
In fact, the only way I could come up with to accomplish this would be to sweep the path in 2D and then to use a series of bend part features in order to put things into 3D. So far as I can tell this works, but back calculating the 2D curve is so backwards and laborious that I can't imagine using this for anything. In Solidworks this is relatively easy using the sweep solid feature .
Completed a project. Wanted to show the customer the end result and go over changes on my laptop. Copied the directory to my laptop. None of the Nuts & bolts will show up on the laptop version. Got a new desktop computer. Same problem. My completed version doesn't show the content center items, Hence drawings & assemblies are always un-resolved. How can I get the Content center files to show up without deleting and reinserting the items.
Also how can I make the content center parts I place into the model reside in the local path.
When I open ACAD A14, the workspace is displayed black (I had it set on white). When I zoom out, the screen is white again, but when I move the cursor, the crosshairs are displayed as a black square and leave a black trail, like for example Internet Explorer on the old Windows systems. I can use all functions normally, however my drawings are not properly displayed through the black. I had it running today already, without any problems, but my laptop was not connected to the internet, now it is. Things I tried: Reinstalling AutoCAD Restarting my PC Disconnecting my laptop from the internet and reopening AutoCAD A screenshot is attached. I am a first semester student and the plan is for a supporting structure of a hall that is due on friday, so its nothing that takes up a lot of computing power or anything.
We have several people in our firm in and out of drawings. Is there a way to pull an audit trail? of sorts in order to find out who worked on drawing last? Or is this information stored somewhere in the file?
Is there a way to create a walk cycle for your model and have it follow a path instead of animating each step? It seems like an incredible waste of time to sit and try to animate every single step the model takes. Also, I want the steps to be persistent. I don't want some to be larger and some to be smaller. I feel like there should be a better way of getting my character across the screen, I just don't know how to do it.
Possible to change/set the work plane while sketching the path of an in-place model? This guardrail extension is an example of where I would have liked to change the work plane while sketching the path because the path shifted planes. I believe you can do this in the family editor, but I could not get it to work in the in-place modeler. What I ended up doing (as an experiment) was to create masses and picked their edges to get the path I wanted. I would love to be able to have more control over the work plane, like defining the workplane by a face and then being able to move it relative to the face selected.
I am trying to create a 3d model of a stockpile, i have the are at the bottom of the pile, and I have the height and area at the top, but there is a road going up to the top of the stockpile. how can I cut that road into my model? It twists around to the top its not a straight line.
What I'm trying to accomplish is a way to create a kit (assembly of loose parts) that will be used in more than one product model. Each top level assembly (product model) will require the parts to be constrained in different locations but all of the components in the kit will remain the same.
Is the iAssembly tool the right tool to use for this?
I've recently been given a *.dwg file that seems to contain a 3D model composed of blocks. I'm a long-time SolidWorks user, and in my parlance, what I've got is an assembly composed of individual parts.
I need to create a 2D version of each 3D part. Currently, my process isCut & paste 3D component into new document.
Select all and perform 'flatten,' removing hidden lines. Select all and explode.
Manually remove a zillion duplicate and unnecessary line segments. Manually fix radiused / filleted corners, which have become a bunch of little straight line segments. Draw a polyline around the whole part. Run 'boundary' to create a new polyline approximating the original shape.
Clearly, this is not very efficient - nor does it produce an exact 2D duplicate of the face of the 3D part; what I get is a close approximation. I don't use AutoCAD to do 3D work, but I assume that, much like SolidWorks, a 2D sketch is created first and then extruded into the 3D objects.
This, in turn, leads me to believe that there ought to be a way to extract that 2D sketch intact for use elsewhere. How should I go about doing this?
