AutoCAD Inventor :: Creating Non-manifold Topology
Dec 6, 2013
Lets say, I have an Extrude feature built on a Rectangle as Sketch Profile. Is it possible to programmatically edit that Sketch, add one line in the middle dividing the Rectangle and replay the Extrude, so that I get Rectangular solid and a Partition surface in between?
This was not possible as a user, but programmatically if its allowed to turn ON some Non-Manifold flag and allow this. If allowed, this probably may not be a single Extrude feature doing both Solid and Surface, but could split into 2 Extrudes.

I have downloaded the SSURGO file from Web Soil Survey. They are in .shp files, I have imported the spatial files into AutoCad Map 3d 2012. My goal is to create a Topology so that I can detemine the soil type and acres of parcels of land.
When I click on the polygon in my drawing it is a closed polygon with double line or overlapping lines and it does has object data but it is part of the line not a point as I am used to.

I am having trouble shelling a part I have designed. Every time I try, with no matter what thickness, I get the following message:
"The attempted shell operation had non-manifold inputs. Try with manifold inputs."

I want to calculate the total external surface area of the attached manifold. When I use the iProperties tool, it give me the surface area including internal surfaces of tubulars etc.

The attached assembly contains 3 parts modelled in slightly different ways. All parts fail when the dimension of 600 is changed to 200 in the Tool Part, probably because a different face comes into play...but it's the same body.

I am trying to shell a multi-layered part that has been union boleaned to form a 3D solid. Once I hit shell, eliminate one face for 3D printing, set the thickness desired, command line reads "Non-manifold edge detected" and restarts the shell command. 1.) What is a non-manifold edge and 2.) How do I fix it?

Whenever a annotative dimension is selected, its text are displayed with virtually all possible scales simultaneously on the screen, blocking the view of other objects and make the screen all a mess. Have a look at the attached picture.
Is there a way to get rid of it?

I've been using cad for a while but only for simple layout drawing for parts I need made.
Autocad 2010 I want to set up a drawing to draw some manifold adapter plates in millimeters. I can set it up for inches but I'm having a problem setting up for mm. I start a new drawing and select the template initial setup-manufacturing-metric.dwt In drawing unitDecimal and precision is set at 0.000 Units is set to "millimeters"
I draw a circle to test it. I draw a circle of 5 radius. Should be a circle 10mm in dia, correct? But it is huge, my guess is that it's 10 inches. I'm basing the size on what is printed out when I set my print to no scaling, 1:1, plot window. The same as I have for all the drawings I do in inches.
Second question.
How can I get circle centers to show on prints without actually drawing them or putting in dimensions?

I am trying to detect overlaps between two different features. They are, at the core, shape files from a GIS system and we have AutoCAD Civil 3D 2009.
I have reviewed the steps to test for Topo within a feature but don't know how to test topo between two features. I need to test for and identify "Overlaps" between feature A and Feature B and when Feature A is "Not Entirely Within" Feature B.

Why I can't create a topology for spatial object (feature classes)? It works only for drawing objects.

I have two set of points with O.D. attached (points_1:data_1 and points_2:data_2). I want each point of the first set get the O.D. of the NEAREST point of the second set. Something like "point overlay". The problem is that AutoCAD Map can't overlay point topologies, and that makes sense, since entities don' t actually overlap.

I have successfully created and defined a topolgy in Map 3D using a Visual Lisp routine that I cobbled together from CREATE.LSP. What I'd really like to do is be able to access that data and create closed polylines and centroids without going through the menu interface. The only documentation that I've been able to find is the Mapping Commands section of the Help file.
I found several commands, but they rely on user input to work. I might be able to work around this by typing a dash before the command line to suppress dialog boxes except for the fact that MAPCLPLINE does not respond to this method.
I noticed in CREATE.LSP that there was a TPM_MTNBUILD command that (apparently) was used to build the topology. Are there similar commands that I just haven't found yet?

Auto cad map 2011...unhanded exception error occurs when I create a large (2500+) polygon topology. In fact, initially I only use acad point for centroids to minimize complexity, until I know the map is clean.. Later, when a topology is assured, I bring in attributes as the centroids. I am only using four layers. Have been doing this for five years...always used acad map 2006 and had no issues. Have had the same problem with all releases after 2008, and was hoping this would be the moment..but it's still the same. Incidentally...I even moved to a 64 bit box,6 gigs of ram and 64 bit 2011version of acad map in the hope that this would go away.. How I regret giving up version 2006.

I have some problems with this drawing. I have some parcels and buildings, and a number for each of them. I attached data to parcel and building number, and I want to create topology and then to create thematic queries, based on any data attached to the numbers. And I don't know how to do that, and how can I use thematic query to show me the specific parcels based on the data I want if the table is attached to the parcel number and not on polylines. Same thing on buildings...
For example: I want to make some thematic maps based on tax value, street where the parcel is located, area, or on buildings: how many levels they have, and more.
I uploaded a example file to be more specific, with data attached to numbers, without topology created (drawing cleanup is done).

I have sculpted several levels of detail on a face and have run into a issue.I have realized that I want to change the topology of the face.How do I go about doing this without losing all of the sculpted detail?

I have an object with about 10 morph targets and I've seen some issues with some shapes, which will need a few more edge loops around the mouth. Adding an edgeloop or any other topology edition to any of the targets or the original breaks the morpher animation.Is there a way to do this? Or to propagate the topology changes to all the morph targets?

I am always having a great problem while modeling knees and elbows. Some people say put three loops on knee and some people say put 5??.. If i put too many loops then it collapse while deforming and when i put less then it won't deform properly...
I just want to Know is there any effective topology technique for knees to deform naturally and which should look realistic while the character is on squatting positions.
Please Check out the attached Picture.

I'm recently using inventor a lot. But now IM try to make a .IDW template with my own line styles and thickness and stuff. This is what I do:
I open an exciting IDW file. I go to manage and click style editor. Then I create a new style. Called test style. I make sure I activate my new style and I go to layers, where I change the line weight from 0.51mm to 0.25 mm (example)
I save my change and close style editor... After that I save my copy as template (called test 6-1) and close the drawing. I open inventor and create a new file. Select the template I created. I get this style conflict.... I don't fully understand this error... How can I fix this problem?
When my new template opens, I check the line weight by the style editor but the weight detente change... Its still 0.51 mm.

I have searched this forum for a way to create 3D pdf files directly from Inventor or other "free" software but have not found anything that works very well. Today I found an answer, it is by using the Bentley Viewer. I had to "Save Copy As" my Inventor .iam file to "AutoCAD DWG Files.dwg". Then open it up inside the Bentley Viewer, go to the "Print pdf" button and select the "Print to 3D" button. It will even show some colors.

Is there anything wrong with creating a new template this way:
1. Create a new model for a new client.
2. Create new drawing based on the standard template.
3. Bring in model views and create new title block, notes, symbols, etc. specific to new client.
4. Save drawing as a client specific template in my template directory.
5. Open new client template and erase all drawing views but leave notes, symbols, title block, etc.
6. Save.
The question is, doing it this way, will it cause problems? Will the drawing views somehow still be linked to the template? Should I erase the drawing views BEFORE saving as a template? Is there a better way ti create a template?

I'm having the constant problem, with IV crashing when trying to export an UK/EU A0 sheet. If I drop down one sheet size to A1 the export to PDF works with out a problem.
I've got the latest SP and fixes installed, so I don't know if it is IV or Adobe XI Pro at fault. Plenty of memory, paging file set to min of 8192 Max of 32768 so there plenty of space, 8MB Ram. Windows 7
What I've tried is save the file as a different name, file is NOT compressed on the HD, the HD is not faulty I've ran several test & checks, the folder & file are not corrupted, no viruses reported after deep scan, so now I'm stuck here wondering why IV will not export an A0 sheet to PDF.

I have to design a new part based on joining two of an already made ones. I thought it would be as easy as a "union" command in AutoCAD... but couldn't find anything that resembles that, and I really need them to be a joint part, since I will be printing them in a 3D printing machine. how I can do that in Autodesk inventor?

I'm having problems creating a boundary patch on the attached model, Its a Y-Pipe joint in 3 planes that I'm attempting to split in half. I've used a silhouette curve to create a centre line in a 3d sketch then joined the ends together, however when I try to select the lines to create the boundary patch it only allows me to select some not all of the lines.

I want to make some icopy tools to suit my needs, i did the tutorial i've found on AUGI "an icopy how to" and then i did a glass panel using the technique i learn there. Everything works fine until i place the icopy on a different plane than the x, y plane.
when i place it in other plane it the icopy behave in strange way. I had this problem since the first icopy test i made and i can't find why it doesn't work.

Is there away to use an IFeature creating a new body?
I mean, modeling a part as multibody, i would like to insert a feature with an iFeature, but i would like too that that new feature will be a new body.
I have tried in many ways.. including inserting in the ifeature a Split Feature..but with no sucess.
