I am trying to create a 3d surface by importing points from an excel file. I have been using "import points" in the 3d sketch mode, and checked off the box that says "create 3d spline." But this just causes Inventor to freeze and crash. My excel file had about 2000 points, all of which lie on the surface I want to create in Inventor.
Should this method work in theory, and do I just have too many points?
i attached a lsp with and excel
the lsp does creat circles with diameter of 5 related to imported points from excel
i realsed that it is able to get the first column but can get the coordinate from the second one
(setq posX (atof (substr line 1 nPos))) (this is ok)
(setq posY (atof (substr line (1+ nPos)))) (not this one)
I have a group of Points coming from a step.file. So I don't have their coordinates, excel list or anything else. Just the step file. Around 100 points. There is a line between each 2 consecutive points.
Is there any way to select all the points and create a complete spline? Or even to select all the points and create tangent arcs between all of them?
I need to be able to extract all "X" and "Y" axis points from a "spline" created in a 2D "sketch" and display them in the "Debug" window (for test only).

Now at certain parts, I would like to increase the thickness and then blend it the rest of the surface(may be chamfer its edges) .
At certain parts on curved surface I would like to add an extra mm, I think if the surface was flat I would just sketch the shape, then extrude it by few mm and smooth the edges by doing a chamfer
But how can this be done on surface that is curved? Or multi curved for edges?
I'm trying to link an Excel sheet to a new assembly but it is only listing half of the sheet parameters. I have done this before with no issues. I've also imported another sheet and it works fine. I copied and renamed a sheet I know that works deleting the data from it and coping the data I want and I get the same results. This lead me to believe there is something wrong with the sheet. See attached file.

View 3 Replies View RelatedI 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?
Attached is design I am working on and I have imported standard parts from Carrlane. These parts are in surface type and I could not see them in Inventor DWG though they are visible in assembly. How can I convert these imported parts to solid or is there an easier way out of this ?

I don't even get an error message... I have tried the same thing on another computer with the exact same spreadsheet and it works 100%.

I'm trying to create an external involute spline (ANSI B92.2M) Fillet Root Side Fit 26.9mm x 1 mm x 26 teeth x 38 mm long using the spline generator with Inventor 2012. I created a test shaft"M-182-AMA.ipt" that is Ø26.9 mm x 38 mm long with 1 mm radius on each end of shaft.
I use the following steps:
1. After creating component "M-182-AMA.ipt" I select Design tab>>Power Transmission>>Involute Spline.
2. A window appears that has the caption "Involute Splines Connection Generator".In the Dimensions section I choose "Splines Type: ANSI B92.2M - 37.5 deg, Fillet Root, Side Fit, 26 x 1.00 x 38 x 5H/5h" and change the Length to 38 mm.
3. In the Shaft Groove section I use Create new, and I push the Reference 1 button that turns blue, I then select the od feature from the model and I get an error(see attached pic "error1.jpg).
I changed the 26.9mm od to be 27mm and it still gave me the error.

The attached csv file contains x,y,z coordinates and the image number per row (only 1 in this file). I am reading in this file and creating a spline knot at each of these points. The last coordinate x,y,z set closes the splines and creates a shape that resembles a US state. I next extrude it a couple inches and it looks like a hollow 3-D state.
My question is how do I go about capping (or filling) the top and bottom faces? I have a feeling it is a bit more complicated because of the large number of knots, around 127, in this shape. As every time I try and follow the cap surface instructions in the reference it doesn't do what I want. Is there any way to automatically or by using a script join the vertices so that it looks like a mesh grid on the top and bottom and then fill in those areas?

How can I draw Spline with fit points in AutoCAD 2013 .NET API using my own jig?
View 5 Replies View RelatedI have a large surface (over 1.5 million points and 20 000hectares)
I need to get a point file .csv from the TIN to be able to use it in another program.
-so i've extracted the points from my surface, but they are Autocad points.
-next step is to convert them to civil 3d points.
-I can not select them all when converting them or my computer crashes.
-so i select about 25 000 at a time, the converting takes roughly 10 minutes.
and i have over 1.5 million points to do.
how can i speed this up.

I have a spline that goes through 4 points:-
x1,y1 - x2,y2 - x3,y3 - x4,y4
The spline is of degree 3 and is fixed at points x1, y1 and x4, y4.
What i need is the equation of the spline.
Is there anyway of calculating the equation that represents the spline?
I am working on a little lisp routine to draw splines, but can't get it working. The basic idea is that i first select a set of points that i can feed to my spline command.
(defun c:test2 () (setq pt (getpoint "
define point:")) (setq ptlist nil) (while (not (equal pt nil)) (setq ptlist (cons pt ptlist)) (setq pt (getpoint "
define point:")) ) )
Now i need to draw a spline based on these points. My plan whas to simply use the acad command itself. But this option didn't work.
(command "spline" ptlist "")
Then i tried using the vla-addspline command. But i can't even get this one working .
As you can see, the nature of my model forbids me from making a 3D solid using LOFT.
The top surface is consisted of 3D polyline and arc, which if "joined" will be become a spline.
The bottom surface can easily be joined into polyline.
If I loft the top and bottom, it'll only give me a LOFTED Surface, which is not I want (wanted a 3D solid).
I am trying to create a 3D meshed surface from an irregular shaped solid I created using firstly a SPLINE, FILLET, PEDIT, and EXTRUDE. I have a solid in the basic shape now, but I am trying to create a meshed top and bottom (x, y, z,) to change the contours of those surfaces. I have looked at 3DMesh but it asks for (n,M,) coordinates like it is a regular shaped surface (square, rectangle) where one can calculate the required even spacing needed.
My goal is to create in CAD something like a fine art carved piece of wood, with irregular shaping and no straight planes or surfaces.

Importing excel files into AutoCAD drawings works nicely but the print is unreadable in some areas of the page. There seems to be no rhyme nor reason to how the plot will turn out.

View 3 Replies View RelatedAny way I can import data from an excel file in a predetermined range but variable workbook and sheet. For instance, in Station5.dwg I access cells B4:C15 on sheet STA-5 on workbook TerminalA.xls and then in Station6.dwg I access cells B4:C15 on sheet STA-6 on workbook TerminalA.xls, but all through just rerouting the sheet just as if I were to reroute an xref with the same scale and insertion point.
I'm trying to avoid a continual copy/paste of OLEs for each .dwg because I will have an average of 5 ranges to import from each sheet, of an average of 7 sheets per workbook, of an estimated 220 workbooks to work through. (7,700 ranges estimated so far is a lot of work).
I'm looking for a script for scattering proxies on a surface or along a spline. In previous versions of Max I used Peter Watje Scatter. But itdoesn't seem to be available for 2012.
I don't have enough use for it to justify buying Carbon scatter or multiscatter and I find render farms don't tend to have these plugins anyway. Forest Pack lite only works on flat surfaces.
I am trying to animate a spline or jointed border object over an irregular surface.I want to add particles to the spline in the end to try to simulate a fire burning outward across a terrain.
I tried booleaning out a border and while that works, when I add particles to it, it overwhelms my computer. I tried using shapeMerge but that doesn't quite do what I want either. Itoo's glue plugin conforms an object to the terrain but doesn't allow me to animate it.
Im totally new to max. Im trying to draw a ship hull. I draw frames and placed in positions then i tried applying coss section modeifier and tried also to connect vertices manulay.
View 3 Replies View RelatedI've just finished up a ground level survey. I've jotted the coordinate and levels down in my notebook and typed them up on Excel. I'm having trouble getting the coordinates from excel into AutoCAD Civil 3D 2013 version.
I'm VERY new to this sort of stuff as a trainee site engineer the most I do is simply take coordinates from a drawing to set out on site. I'm importing the points from file using Civil 3D.
I've simply saved the coordinate on excel as, for example:
430245.454 434264.654 62.321
I get this error "No point file format match found" when I try and import them. I've had a look at some Youtube videos and I'm not sure what I'm doing wrong. Maybe it's the file type I'm saving it under.
I have a user that imported srrvey points and after getting all the points in and set up has discovered that the point over 100 have an extra 0 in between the letter identifer and the point number so instead of A100 he has A0100 , there are several hundred point descriptions to change is there a way to get rid of all the extra 0's without editing each one.
