Successfully drawn a eggshape for tabletop using 3 ellipse and arcs and converted these into polylines but having trouble converting them all into 1 polyline for lofting.

I have drawn a 3d polyline across a stream channel and want to rotate it about the x-axis so i can trace the elevation profile of the crossing. 3d rotate in civil 3d 2012 is not allowing me to pick the axis i want to rotate about? This worked great in previous versions? This is very simple and i dont have a need for a surface or sections or profiles...i just want to trace the 3d polyline profile.

View 2 Replies View RelatedI understand how to get a shape drawn in cross section view -- assign a shape to the area in the SA. I've done that but now I need/want to take the next step.
Using SAC, I created an SA that draws my RockFill but it only shows up in cross section view.
How do I spec that I want the shape to show in plan view too? the shape in plan view should be the daylight line on one side and the RockFill Line on the other side.
I just read the thread the thread "...plus ask about erasers" but it doesn't answer my question about combining shapes to remove unwanted portions - or at least I didn't quite understand it. Here's my issue. I've created a nice "background" image with ripples and live effects, but it has gaps, and isn'tthe right shape. I need to erase parts of it and clip it to the right shape, but every time I try to do this using the slice tool, it puts the gaps back into the image! Attached is my image and the shape I want to clip it to.
I just tried converting the ripple shape to a bitmap copy and then slicing the shape - that doesn't get me the rippled effect I want - just the shape I already have. Then, I tried just creating the water ripples in my shape - but again that leaves gaps and when I try to "slice" them away it does all kinds of weird things to the shape..
Although I have found code that should allow me to convert 2dpolylines to regular polylines, I am having troubles implementing it. At first I got the eInvalid Input but have since fixed that. However, the error now is that there is no error. Autocad just seems to lock up but I can still switch to visual studio and look at my code. It as though Autocad thinks it is doing something but my code is not doing anything. I can scroll around.
My code is this:
Try Dim acDrawing As Document = Application.DocumentManager.MdiActiveDocument
Using acDrawingLock As DocumentLock = acDrawing.LockDocument
Using acTransaction As Transaction = acDrawing.Database.TransactionManager.StartTransaction

is there any solution you know?otherwise i have to closed them one by one.
I've created a very basic shape using the 3D grid as my guide - picture if you will 4 boxes, one on top of each other (as per illustration below):
Each "box" is made up of 3 shapes to give the 3D effect.
I need to resize one of the boxes, the yellow one, which needs to be resized in keeping with the 3D framework (making it smaller in height), and then placing the yellow box above the purple box. How this can be done without having to redraw the shapes in the required positions.
I might add it is the grouped shapes that makes up the box which I am trying to resize in one hit, as opposed to the individual shapes.
I have a cartoon line drawing. The black outlines are anti aliased so the edges of the lines have different grades of gray pixels on them. When I use the fill tool, and adjust the fill with the opacity and tolerance sliders, (I think that's what they're called in GIMP), I still can't get what I want. Only some of the gray pixels are colored in. Others are canceled out. Completely covered by the color, erasing some of the line.
Or some pixels remain uncolored. Just gray instead of a combination of the gray AND the fill color. What I'm looking for is an effect that looks like I placed a colored gel shaped like the cartoon character over the drawing. All the different shades of gray pixels should still be seen. Even the ones that are lighter than the fill color. With a gel, those pixels would appear darker, even though they were lighter than the fill color without the gel over them. The darkness of the color PLUS the added darkness of even the lightest gray pixels should make all the pixels appear darker. And the line would appear complete. Not partially erased.
Is it at all possible to get this effect?
I recently exploded text but now i need it to be a Polyline, when using PEDIT.
View 1 Replies View RelatedFor some reason after drawing shapes with the shape tool, whether it is one line or a custom shape, I just can't edit it after drawing it. I can't edit it at all and it doesn't appear on any layer. I can delete every single layer and the shape will still be there.
They are not paths, but just to double check I did look under paths but it is empty. It doesn't matter what else I've done, or whether it is a new blank page I can't do anything with any shape once I've drawn it.
I can't get it to select it when I click show transform controls, I can't select it with the marquee tool and delete it (because it isn't on any layer) and I can't place anything over it to cover it.
I have to keep saving before drawing any shape and close and reopen the file if the shape doesn't go quite as I wanted first time. Obviously if I want anything over the shape in any way I can't do it.
I draw a T with the pen tool, supposed to be vectorial, that is, you can enlarge it without losing quality.
But the top edge appears pixeled! Why??
Is there a simple way to add a vertex anywhere you want in a shape or polyline? I double click those items and a menu comes up and I can add a vertex but it limits me where I can add the vertex and then it is a pain to make it work like I want.

How can I do that?
The surveyor's CAD file includes a boundary line that is mostly curves. It's drawn as a spline. I'm trying to create a PROPERTY LINE in Revit. I've converted the spline to a polyline in CAD. In Revit, PROPERTY LINE sketch mode, I can hghlight the polyline but can't select what I've highlights. Only one of the polylines gets selected. So I have to try to select them all one at a time. converting a spline to polyline in CAD for use in REVIT?
View 2 Replies View RelatedI have been sent a client's construction drawing for a care home where i need to design the sprinkler installation. The majority of the rooms have got the same head positions within them, but they have all got a slightly different angle as the building is shaped like a banana. Unfortunately its not a uniform radius that i can tell as the one side is larger than the other.
So my question is this. Normally, on a square building, I drop in construction lines along the bedrooms so that i know my sprinkler heads are all the same distance off a wall, and I only need to line up one side. However, with this building being a curve, and the wall angle being slightly different on each room, how do I place an angled construction line or polyline to act as my set out line for my heads.
I need to convert shapefiles to a pretty old version of dxf. Shapefiles is a file format used in geographical systems.
[URL].......
For example a shapefile could contain points, lines or polygons, and attributes for each point/line/whatever.
Now I need to convert shapefiles to an old version of the dxf format, I don't even know exactly what version so I'll have to find out by trial and error I guess. (But a gut feeling says somewhere in the 90's.)
Luckily there are tools to convert shapefiles to the modern versions of DXF, but where do I go from there?
Any routine that would allow you to cut out an odd shape from a solid with the profile of a polyline?The goal would be to have all the pieces that are left, not subtract them out..
View 3 Replies View RelatedI've been working on converting a vector into a shape and am having no luck. I've done this before and have had no problems. I import my vector .ai into AE as a comp (sequence tickbox not selected). Once I've got it in, I drag to the project, then click layer > create shape from vector layer. My shape populates at the top, my .ai file is off and what is just one of the three colors, along with the shap. I've checked the the shape's contents, every group has the correct fill with the correct blending mode.Also, I've tested other logos with the same results--one color displays while the others don't. I'm working with "ray-traced render engine" And, I've reset my preferences.

I think for the moment I'll skip the mouth and ears and eyes aren't so hard to sort. What I can't find however, is any information on how I would go about making the face, hair and neck. What seems easiest for a cack-handed individual such as myself is to use a photo (flat-lit, straight-on, neutral expression, unobscured) of someone's face and then deform it and use some clone-like tools to fill in any gaps.
Obviously I'll need to match the coordinates of particular points on the face and keep large sections entirely unmodified. Then I'll need to do some sort of cloning or smudging to extrapolate bits of the head I don't have.
Well, is it even possible to work from a photo (or couple of photos).

View 3 Replies View RelatedIm trying to make a 3d model of a site in AutoCAD and it seems lofting between some contours is impossible, this is driving me insane, first it told me there was a U and V derivative problem so i loft the surfaces that i could but now there is a gap where it refuses to loft and i cannot create a surface in that gap using network or blend or pach.
View 3 Replies View RelatedI have to do a lot of lofting to create 3D shapes. The more the 2D sections are complicated, the more times takes for AutoCad to find a solution (even in a powerful computer). Beside that, I use Guide splines to create the exact shape I want. For this I have to wait two times, first Autocad find its own solution, then the solution with my Guides. Is there a way to make AutoCad loft by default with Guides, such that it doesn't ask for Guides after the initial loft, but immediately at the beginning.

I'm trying to loft a base for a light fixture. It's narrowest at the top and bottom, and its widest point is in the middle. classic design.
Can I upload a pdf? I assume if it's available to everyone via a search engine, wouldn't it be ok to upload it? Any thoughts?
I digress. I'm trying to look at the circles from the side, so they form horizontal lines. I thought they'd be easier to offset a distance to.
I tried changing my views around to achieve that effect, but to no avail. UCS is World view. Or View.
One of the images in the .pdf, is of the appearance I'm after in a front view. So that way, I could do an offset distance of one inch, but as things stand now, that wouldn't work either.
It wouldn't work in this view projection, I think was what the wording was; or close to it.
The only view I was able to do any offsets in was the Top view IIRC, but that just gave me a bunch of concentric circles with no height. At least they were offset.
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.

Basically we are trying to make a 3D plate (in this case a 2" thick piece of steel) and have a 3D hollow shape inside. Its split into Top and bottom, as shown as the below picture.
top View (plate 1).jpg
I have tried the loft command (which I just learned off within the past hour or so) and it indeed works. But I wish to use its as the opposite, where the middle is hollow and the rest is a solid object.
Side View (plate 1).jpg
I have tried the loft command (which I just learned off within the past hour or so) and it indeed works. But for the life of me does not know how to get it as one big object with the middle shape hollow. Am i missing a step or is it another command completely?
Also, once the object has been created, I want to split the object on its X axis mulitple times, almost like an exploded view. Each split will have its own set of top and bottom orifices which will represent multiple plates.
Is there a way to do that? Also is there a way to gain and separate the top and bottoms of these newly split plates?
Here is the drawing file as well to work on -> 3D-MK1.dwg
In previous autocad version that supported Lofting, i was always able to create a solid loft.
With 2013 the loft command seems to divide its abilities depending on what type of profiles are selected.
When selecting a closed polyline profile, loft produces a solid. Works fine.
When selecting a region or solid face loft produces only a surface.
The work i am trying to do at the moment involves irregular sections and/created from existing solids.
I could trace the profile and make a polyline, but each profile contains an ellipse, and you cant trace an ellipse.
Where i used to be able to select the ends of the existing solids and create a solid loft,
I now have to produce a section twice (gives you a region), loft the regions, convert the regions to surfaces (because the produced surface doesn't have and faces), union the surface and then convert to solids
Instead of 1 command there are now 6.
I tried turning of the assiciativity (surfaceassociativity 0) hoping that it had some sort of influence but to no avail.
There was no issue with 2010 and 2012 and i have just installed all 2013 products.
I have a lot of work to do and have to produce 3dsolids.
I am working on creating a male mold for a canoe. I first designed the cross sections for the canoe and then began converting them to the mold cross sections. When I try to loft the cross sections I have converted so far, they all loft as I intended until I get to the rear of the canoe (sketch 8). The issue typically arises in gunwale section (the part that appears to be a notch in the sides). Everytime I loft, one of the gunwales splits/twists in an undesired fashion (in the image below the right gunwale is incorrectly twisted).
I do not understand why this is happening for a few reason:
1. The canoe cross sections lofted as planned, and I only added simple boxy shapes to those cross sections.
2. Each cross section is symmetrical (or at least from what I can tell they are).
3. The cross sections that are lofting improperly all have the same number of segments and are in very similar shapes.
I have attached the file of the cross sections and another file of an improper loft.
Coming from Sketch up to real big boy tools. I watched the tutorial videos and tried poking around a bit for this specific answer but came up a bit short.
What I'm trying to do is loft a face to a point. Easy enough. I've got my point established on an offset work plane, and I can just loft to that, however, I get nothing but straight lines. (First attachment)
An example of the ideal outcome in SketchUp is the second attachment.
I'm having the most difficulty trying to draw the curves along which I want the face to be lofted because, even as I sketch along my 2D plane, I can't snap the endpoints of my arcs to the endpoints of the face (or the point to which they'll all connect).
