AutoCad 3D :: Sketch In 3D Of Truncated Pyramid - Twisting Vertical Structure
Oct 24, 2011
I am trying to produce a sketch in 3D of a truncated pyramid, base 11 meters square and top 20 meters square. Its 80 meters high and I need to twist the top 45 degrees to create an iconic tower for a friend in Brazil.
Have drawn the pyramid but how can I twist the top and make the vertical lines follow?
My issue right now that I can't seem to find an answer to is it seems that when a certain engineer in my office opens a drawing at her computer and saves it, the drawing is slightly "twisted" i guess you could say.
I have a fix to this issue, for example, I use DVIEW and change the points to 0,0,0 and 0,0,1. Which works just fine and fixes it. But for some strange reason it seems like after she opens the file and saves it, the target point usually ends up as something like 1.35454,2.5664721,0.0000076 And I know that the last coordinate is what causes the problem.
I'm just curious if there may be a variable or something set on her computer that would keep causing that to happen when she opens a drawing so that I can set it back to default and eliminate the time spent on running the DVIEW command on every drawing that she opens.
I draw 3D curved handrail, mainly just rectangular because i import the geometry in to Alphacam and run tool paths down them, but i keep getting faced with the problem of the twisting of a solid when sweeping along a spline or a 3D poly!
We use C3D 2012 (metric only) - We are attempting to customize our list of structures for Sanitary Sewers. The structure list shows sizes we do not use and we would like to modify them. However, when we try to select the "Inner Diameter" it displays a list of sizes that we can not seem to modify or add to.
I have looked at some of the XML files to try and modify or add new sizes (example: AeccStructConcentricCylinder_Metric.xml) , but they do not seem to be recognized even after I restart the program.
One good thing about null structures is the way they display in 3D. They cover that gap in the pipe segments. Can I steal that shape? I am currently using a simple cylinder for water pipe "joints" and turning it off like most people do I think.
I have drawn a pipe network with multiple concentric sturctures. I need to make them all eccentric now. Is there an easy quick way to do this, or do I have to redraw all of them. When I go to the properties, I cannot find an option that allows me to change this.
I am creating three shapes out of a pyramid. I figure if I split the pyramid in half, I can create two, then mirror them and blend the two together to make the final design. I have figured out how to create a pyramid by extruding a cube with a taper.
My pyramid is 40mm x 40mm x 40mm. I need to cut it in half, diagonally, top to bottom.
When I have the pyramid in the workspace, I see nothing that I can select - that will allow me to create lines where I need to - to cut them out.
I'll add a logo in 3-d that I am trying to create. (also, I am using this project to familiarize myself with the software.)
Assume that I have an odd pyramid 3D-solid say with a polygon basis that lies on a "floor". The apex was higher than the ceiling, so I "sliced" the pyramid to fit it right under the ceiling.
Now, I change my mind and want to make the ceiling slightly higher (say, 1"): after raising the ceiling I am left with a sliced pyramid that is cut 1"below the ceiling. Question is : what is the best way to re-extend the pyramid (and make it look like it was cut by the higher ceiling) ?
I cannot just "undo" because too many things happened in the meantime.
I can imagine re-creating the unsliced pyramid by press-pulling the upper sliced surface and then slice this extension with each side of the original sliced pyramid and ultimately re-slice with the new ceiling. Can I do better / faster than that ?
I want to create a pyramid with a base of three sides with different lenght. In the end i want to have a solid where i can drag and move the notes to change the hight,lenght and the angle of the sides.
I already managed to draw it in 3d but now i want to convert the drawing into a solid and keep it flexible to change the parameters by draging the notes.
I also tried to extrude a triangle with a specific angle but then i was only able to move the top note up and down changes the hight. Doing it this way the top note also kept beeping in the center-point of the triangle.
I am importing a Gis (2007) shp file into C3D 2013 (Attaching Query and everything else) and everythings seems to be working. However, I get an elevation of 3 for all contours (Even before the Query a 3 feet elevation is depicted in the properties windows).
The only reason behind this, that I could think of, is that C3D is not reading after the 3.***** in the dbf file.
In LDDT 2009, I was able to describe points like this: STK #32
But in Civil 3D 2013, whenever I use the # symbol, the description gets truncated. So, using the point description above, it will show up in Civil 3D 2013 as STK rather than STK #32.
Is this a setting or something that I can switch on so that the I can use symbols such as # and - in my point description?
I think you will see from the pic my line mabel do not = the distance or property mesurement. all the labels are truncated so there is no auto rounding..
I am trying to get my points to displey the " mark from our descriptions. The description keys are set to $* and I have tried changing the Label Style from full description to raw description. I cannot get any information after the " mark from our field data. LDD used to put it in, but civil 3D truncates the information. I know I can do a find and replace in the .csv file, but would rather not have to continually edit the .csv file. Where the setting in civil 3D is to allow this to happen? I have even messed with the Point File Formats to no avail.
I have been trying to create a 3D pyramid using Illustrator CC. All the tutorials I have found have been telling me I need to create a custom bevel, but the Bevels.ai file is not in the plugins folder as it used to be. How do I create a custom bevel in Illustrator CC?
I have been using Elements 8 for some time and recently purchased an ASUS monitor that is at home in both vertical and horizontal modes. Can I change the Elements 8 format to work in a vertical format to accommodate the larger size possible with a vertical image. It is difficult to manipulate the functions in Elements when the mouse is working in a horizontal mode and you are viewing a large image in a vertical format. If the format of the Elements 8 software can be changes to vertical, any protocol (directions) to accomplish this?
While using the 3D extrude and bevel tool, specifically the isometric preset from the position drop down menu. I am noticing that when I expand the shape (in this case a perfect cube), the vertical paths are not exactly perfect, and are not truly vertical, but off slightly. Is this something that can be fixed or adjusted in the settings, or is this how the tool works?
I'm following a "Simple Mass Creation" exercise in a Revit book, which says to create a cube, a sphere, and a pyramid. It doesn't say how, though, it just goes on to the next step of dividing the masses into floors. After much research and trial and error, I figured out the cube and sphere, but how the heck do you create a pyramid? At first I was thinking of a blend, from a square to a point, but that's not an option. Then I tried to use void shapes to remove parts of a cube...and I'm getting an error message because my voids are overlapping and there's no solid to cut. There MUST be a faster and less complicated way to create such a basic form.
I have a weird bug in CS6 Photoshop... all brushes, at about 30 size, are getting truncated on the circle. Paint brush, background eraser, doesn't matter... most of the times all I see is the brush outline from 9-12 o'clock. The other 3/4 of the arc are gone. As I make the brush smaller, I see more, and as I make it larger, even the center cross hair starts to disappear.
CS5.5 has worked like a charm until a week ago. All of a sudden pictures I had worked on in PS and saved back to LR3 showed up in LR corrupted. When trying to open them in PS I get the following message: "Could not complete your request because a JPEG marker segment length is too short (the file may be turncated or incomplete)."
Oddly, it does not happen to all files I work on, though I am fairly consistent in using the same procedure: I import from my camera to LR (3.6) work on the RAW file in LR and do my fine-tuning of the shot in PS (PS 12.1 x64). In PS I save the file back to LR by using "Save" and add an additional file to an external disk in .jpeg format using "Save as ...".
Another odd thing is that there also appears to be a time issue connected to this. After working on my photos, I upload them to my website, and it works fine. After I close PS/LR and reopen again (there could be a reboot in there sometimes), the pictures that were fine previously, are now corrupted. In LR the pic is missing the bottom third (gray snow), split and a color level is missing.
If I try to open the picture in Preview, it tells me the file is empty. Quick Look will show the thumbnail, but nothing more. The file in its folder is obviously only the thumbnail as the size is somewhere between 80 - 120 KB.
I recently updated my OS to 10.8.2 ...Obviously, this is no way to work. Is there some workaround for this problem, short of having to invest in CS6 and LR4?
Addl info: Nikon D300, files imported directly from camera without card reader. I use Topaz and SilverEFEX Pro 2, but it does not appear to have an effect on the truncation Processor: 2x2.4 GHz Quad-Core Intel Xeon; Memory: 16 GB 1066 Mhz DDR3
When I try to open a large (98MG) tiff file in PhotoShop, I get the following message: "This file may be damaged (the file may be truncated or incomplete)." When I continue, the image appears with a blue line through it. I am, however, able to view the file using Microsoft Office Document Imaging, and the image is perfect.
I don't know why, but lately, I don't have any options available when I go to export an image. Once I click "Export" from the file dialog box, all I get is this three-button Help/Export/Cancel dialog, and I can't specify any options relevant to the export format.
Is there a way to correct the slight inverted pyramid effect caused by a 17-40 when taking interior room shots in Lightroom or do I have to go to PhotoShop to do this? I have found the lens profile correction but are there other tools in LR to use? What I am seeing is a slight outward shift from floor to ceiling on side walls and need to straighten these walls.
