AutoCAD Inventor :: Analyze Sketch - Total Number Of Lines In Loop
Jun 28, 2013
Being all new and complete virgin-like, to ilogic, I would like to know wether it is possible to analyze a sketch (wenn it is being closed)?
What I want to analyze is:
Does the sketch contain a fully constrained closed loop?
Does this closed loop consist only of straight lines?
What is the total number of lines in the loop?
Next fase is:
Create an excel-sheet with the following information:
For each line in this closed loop i wish to add the length of the line, and the angle to the next line (consequently on the internal side of the loop, resulting in angles from 0 to 180 degrees).

I am not sure exactly why this is a limited feature of Inventor 2011 but when you want to select a sketch to create a boundary patch you have to select each part of the sketch in sequence. It's a pretty laborious task. I am looking to a way to automate this using i logic.

I have been trying to create a macro that would add a custom property to my sheet metal parts that would tell me the total number of piercings in the part (holes and punches). So far I have the punches to count correctly but I am having issues with the holes, as I am getting an error.
Sub Piercings() 'Get the part doc and sheet metal component defn. No error handling: Dim oPartDocument As Inventor.PartDocument Set oPartDocument = ThisApplication.ActiveDocument Dim oSheetMetalComp As

Is there any way to make 2 to sketch lines instead of floating lines so that I can dimension them?
For example, if I have a part that can change lengths and I need to print off a new drawing, it would be good if I could say that the lines were a set distance from each end of the part or some features of the part.
Then I could update the part length, then just open the part drawing and not have to adjust anything.

I have selected several lines (not pl or spl), just lines, all of which are the same layer and such. I want to be able to select all thirty or forty of the lines using either the select similar (lisp, AC2010) or quick select and return a total length of all of the selected lines. In the properties box it shows as varies.

When you're working on a sketch in the part environment the status bar shows the number of constraints needed to fully constrain the sketch. For example "2 Dimensions Needed".
How do you retrieve this value using Visual Basic Net?

Is there a way to return the total number of layouts in a drawing file?
I would use it to update a field showing the total number of sheets in a set.
(eg 2 of "X", where X is the field variable).

Cant figure this out - I create a sketch in a drawing, but I cant see the lines as I'm drawing them. The lines are on a "solid" layer set to red as defined in my standard. The background of my drawings is black. When the line command is done, the line appears and it's red. Problem is I cant see it as I'm sketching. Is there any way to modify this? Can I have the line appear red (or white) as I'm sketching?

Just getting started, gone through all the tutorials back in 2008...
first time I've actually tried to make something,
Can't use the sketch b/c there's probably a gap in the outline, is there a quick fix?
(Did the entire thing in snap to grid, was hoping there's a function to either connect lines all at once, or ignore Extremely small gaps).

In sketch mode, there is a function to split lines, but I don't see one to join lines.
(I'm talking about colinear lines with the ends touching - I want to convert two lines into one).
It may seem trivial, but I'd like to use these lines in frame generator to select by a single line and not by endpoints of two different lines. Less clicks and more consistency in my model.

When I am in sketch mode I can draw a rectangle and when I go back to dimension it it only adjusts that specific line and not the connecting lines. Is there a setting or command to fix this?

I know about the pink lines, green lines, and black line, but I recieved a part from another person and it had red lines for the sketch, how, what did he do to get those? He doesn't know how he did it.

I opened a part today and noticed that it had collapsed into itself.
This should be a rectangle 85x15.75:
On closer inspection it appears that the vertical lines somehow became zero length lines. Why does this happen?
Edit: I should mention that I was able to repair the skecth by making the 85" dimension driven, then dragging the line over...

I am having problems with lines disappearing in a sketch randomly. I am in a small assembly, going in and out of sketches used for machining, and then the sketch lines and dimensions will all be gone when I enter a sketch. If I hover over the sketch in the browser I can see the lines highlighted, but when I remove my mouse the will disappear. I cannot interact with the lines or dimensions at all. If I draw a new line, it immediately disappears. I have tried changing some things in the view tab and settings but haven't had any luck.

I have an oddly shaped flat plate extruded from a sketch, the sketch of which has lots on constructions lines, none of which actually represent solid edges of the plate. However, I want to locate the plate to other components via the geometry defined in the sketch.
I find that when I am trying to constrain the plate to other parts none of the sketch geometry is available to me. Points, lines, construction lines, circles; I can select none of it when constraining. I am confused. How can I constrain such a part?
Just to clarify - the flat plate is the base of a structure. Its profile is decoratively shaped, so nothing about the cut edge of the plate is suitable for constraining to. I need to constrain off geometry defined in the sketch.
I have "Shared" the sketch.

I have created a chassis wireframe using 2D and 3D sketches. In frame generator, I am able to insert frame members on the 2D lines, but not the 3D lines. I can put frame members on 3D lines ONLY if I use the "insert members between points" placement, but then I can't merge several members together to create 1 tube (can I?).
How do I put frame members on 3D sketch lines using the "insert members on edges" placement?
OR
How do I merge tube members when they are inserted using the "insert members between points" placement?

I have a question regarding copying geometry in drawing mode.
When I was working in V5 and making drawings I sometimes had to "fake" geometry, the world is not perfect I know, copy geometry in the 2d, like center lines and such. I am trying to do the same in Inventor and use the project geometry button and geometry is created but it does not show up when exiting sketch.

Is there a quick and easy way to get the total number of layers in a photoshop document? I've searched high and low, and everything I've found involves scripting, which I haven't gotten into - and don't really want to spend much time on this.

I am looking for a way to extract (filter) all polylines, and loop a lisp based on the number that are found within a "W" selection window.I am frustrated getting "malformed list" or errors, even after defining "n" for repeat.The code I have so far looks like this:
(defun cWW (/ p1 p2 sspw myObj ss)
(setq p1 (getpoint "
Pick first corner: "))
(setq p2 (getcorner p1 "
Specify opposite corner: "))
(if
(setq sspw (ssget "W" p1 p2 '((0 . "*POLYLINE")))
[code].....
Without the (repeat () portion, it was working ok with selection window, however it only would run the commands for a single polyline. What needs to be done without overhauling the code? The lisp has worked on a drawing-wide basis, however needs to run on only on user-windowed polylines since there are other polylines within the drawing which are attached to layouts via viewports.

I would like to export sketches, but leave off the construction lines as they all show up the same in my CAM program. Is there a way to not export the construction lines? Possibly using the "Post Process" options of the Export Options. I am using 2013.

Is there any way to hide construction lines in Part & Assembly sketches in the same way you can in a Drawing sketch?
I know you can change the line colour to the background colour but this makes the lines invisible in sketch as well.
Not being able to hide the construction is making some layouts pretty pointless since relevant detail is obscured by the construction lines. Grounding the geommetry and deleting the construcion lines isn't an option since the sketches are part of the design development and not fixed.

I am using Inventor 2012 and have recently experienced a problem with the fillet not working correctly. I have a curve and a straight line that connect and when I select fillet it will allow me to select the curve but not the straight line. I have been able to do this in the past with no problems.

I'm wanting to have vertical and horizontal construction lines already created whenever I start a sketch so that I can set symmetric constraints to the part I'm drawing up. At the moment, I have to draw both lines every time and constrain them to the center point. It would be much easier if it was already there when I started so I can start on the sketch right away. Is there a way to do this? I've included a photo of what I'd like to do.

Is it possible to isolate the interference detected by Inventor? I am thinking something trough the API or ilogic?
When we analyze interference we get a long list from inventor and sometimes is hard to see it. I am thinking maybe to Isolate the two parts that interfere.

I have a newly discovered issue with left clicking and moving lines and points in 2D-sketch.
After working in Inventor for a while I cant move lines and points(green and unconstrained geometry). If I exit 2D sketch mode and enter again I can move a line once and then its back to not being able to manipulate the geometry at all, the curser just want to create a marking box.

I have a large group of lines that I want to get a total length of. Right now the only way that I know how to do this is to highlight them all and use the list command but then I have to go through the text box and write down each line length and then add them up. This is fine if I have only a few lines but when you get into the hundreds or thousands it becomes a monster task.
I tried copying the text box data into a Word document, removing all of the text except for the line lengths and then dumping that into Excel to calculate. This works ok for a hand full of lines but is not really practical.
I know that there are LSP routines that can do this in the full version of AutoCad but LSP is not supported in AutoCad LT.
Is there a way to automate this process in LT?
Or maybe extracting just the length data from a line to a text file where I can send it to Excel and use Excel to add up the lengths?

Why can i use lines from a 3d sketch to constraint a part to a skeleton base part?
I have attached a example where i try to constraint the tube.ipt using 3D geometry lines of the part Layout_3d_sketch.ipt in the assembly teste.iam, but i'm unable to select any lines from that file.
Why can't i use this 3D sketch lines in a skeleton base part?

I have been searching for a macro to export the start and end point of a line coordinates to excel, but I can only find information on how to export 3D Points.
Is it possible to program a macro that allows me to export the start and end point of various lines in a sketch?
The objective of this is to connect an excel file which is updated when I create a line with it correspondent points, then i could not only import these x,y,z coordinates from excel to inventor but I whould be able to update my spreedsheet whenever I change my sketch.
