IN-Screenshot Free Addin for Autodesk Inventor

Posted on by

This post is for all Autodesk Inventor Users. How many times have you felt the need to take a screenshot of your Inventor file (assembly, part, drawing etc) and send it across to people who do not have Inventor or even upload the image online. You would have to follow one of the following two options

Option A: File > Save As> Save Copy As> and then select .jpg or .png as extension and save the file.

Option B: Use “Print Screen” key on your keyboard, go to MS Paint or other image editing software, paste the copied image and then save it.

At AR-CAD, we have developed a simple addin for Autodesk Inventor which lets you take screenshot or capture the current view of Inventor and save it as a jpg / png / gif or bmp image. And the best part about this addin is that its for FREE !!!. The addin developed is pretty simple and we just wanted to help Inventor users. We have developed the addin using Visual C#. Below images show an overview of IN-Screenshot usage in Inventor 2009 and Inventor 2010 (which has a Ribbon User Interface). To know more details and download IN-Screenshot addin, check out AR-CAD website.

It presently works on Inventor 2009 and 2010 versions and should also be able work on 2011, when it would be released. We have tested it to work on both 32 and 64 bit OS of Windows XP, Windows Vista and Windows 7.

You are free to try the addin and let us know your valuable feedback.

Disclaimer: Some days ago, I had come across a blog post pointing to ADN Addin of the month being awarded to a similar Inventor addin which saves the active view as an image. I had developed IN-Screenshot atleast an year ago and have no link with the other addin.

Minimize forms along with Parent Application or Form in C#

Posted on by
112

How to minimize forms that belong to a particular application, when the parent application (In my case Autodesk Inventor) is minimized ? When you create software or addins, you would want the forms/dialogs to be minimized and not floating around when parent application is minimized.

For that we need to deal with hWnd of parent application. “hWnd” stands for Window Handle, which is the API call to the window(parent application). Since we come across this too often in Inventor customization to make addins, I have created a Class and a couple of methods for better clarity. Before I go into details, lets see what are the different types of Forms/Dialogs you would deal while developing Windows based software.

1)Modal Forms or Dialog Box

Modal Form

The modal forms are used when you want the user to enter some values and unless the form/dialog is closed, he/she cannot interact with other controls in the application. All the MessageBox’s are of modal types. The image on the left is also an example of Modal forms. Here, the user has to enter/select details of Graph plots in our addin IN-Motion.

2. Modeless Form

The modeless forms are used when user can enter values into the form and also can interact with other controls in application, even when the form is not minimized. The image on the left is the Simulation playback deck in IN-Motion.

Coming back to our problem of minimizing forms with parent application, below is the code. If the user minimizes Inventor application(parent form), its child forms are also minimized.
[sourcecode language=’c#’]
//
//Declare and set..here m_inventorApplication is the application
//MainFrameHWND returns its handle.
//WindowsWrapperForForm is a Class, defined at the bottom
WindowsWrapperForForm m_windowsWrapperForForm = new
WindowsWrapperForForm((IntPtr)m_inventorApplication.MainFrameHWND);

//Declare and set a form .. ModalCmdDlg is our modal form
ModalCmdDlg m_modalCmdDlg = new ModalCmdDlg();

//Declare and set a form .. ModelessCmdDlg is our modeless form
ModelessCmdDlg m_modelessCmdDlg = new ModelessCmdDlg();

//Show Modal form
ShowModalForm(m_modalCmdDlg);

//Show Modeless form
ShowModelessForm(m_modelessCmdDlg);

//Methods
private void ShowModalForm(Form _modalCmdDlg)
{
_modalCmdDlg.Activate();
_modalCmdDlg.ShowInTaskbar = false;
//ShowDialog is used..for Modal forms
_modalCmdDlg.ShowDialog(m_windowsWrapperForForm);
}

private void ShowModelessForm(Form _modelessCmdDlg)
{
_modelessCmdDlg.Activate();
_modelessCmdDlg.ShowInTaskbar = false;
//Show is used..for Modeless forms
_modelessCmdDlg.Show(m_windowsWrapperForForm);
}

//Below is the code for Class WindowsWrapperForForm
//****************Class***************

class WindowsWrapperForForm : System.Windows.Forms.IWin32Window

{
private IntPtr m_hwnd;
public WindowsWrapperForForm(IntPtr handle)
{
m_hwnd = handle;
}
#region IWin32Window Members
public IntPtr Handle
{
get { return m_hwnd; }
}
#endregion
}
//****************EndClass*******************

Opensource C# Graph Plot Library – ZedGraph

Posted on by

Update: Check out Zedgraph C# Graph Plot Example Application , I have an example ZedGraph Application (with sourcecode) to draw Line Plot, Bar Graph and Pie Chart.

Update 2: Check out ZedGraph C# Graph Data Export to CSV Using a Custom Context Menu , It has code to make a custom context menu item and also export the graph plot data as CSV.

ZedGraph C# Graph Library

I was searching for an opensource(hence free) Graph plotting library in C# (or VB.NET), so that it could be used in our IN-Motion addin for Autodesk Inventor. After some googling, I found 2 suitable open source libraries namely ZedGraph and NPlot. When both websites(read wiki) were compared, I found ZedGraph recently updated and also had great documentation to take off immediately. I readily downloaded the latest version of ZedGraph dll from its SourceForge project and followed the instructions on ZedGraph wiki.

Within no time, I was ready with ZedGraphTest example, whose screenshot is above. It is so simple that, without even exploring, I could accomplish basic graph plotting. Some of the plus points I see in ZedGraph are:

  • Not much tweaking of source-code is required for basic tasks.
  • All the plot elements (line, curve, panel, axes, plot-markers etc) can be set different colors. Even gradients can be set to have crazy as well as good looking Graphs
  • Different types of graphs (line,bar,pie etc) are possible with ease.
  • Using left click on the plot panel, the graph can be zoomed
  • Middle button can be used to pan the plot
  • Upon right click over the plot, a context menu appears which, out of the box has a lot of useful features such as saving the image, toggle the on-hover highligthing etc
The code for my ZedGraphTest is below. I have changed only CreateGraph() method, and the remaining code is same as in the example.
[sourcecode language=’c#’]
private void CreateGraph(ZedGraphControl zgc)
{
GraphPane myPane = zgc.GraphPane;

// Set the titles and axis labels
myPane.Title.Text = “ZedGraph Test”;
myPane.XAxis.Title.Text = “theta (angle)”;
myPane.YAxis.Title.Text = “Sin (theta)”;

// Make up some data points from the Sine function
PointPairList _list1 = new PointPairList();
for (double x = 0; x <= 360; x += 10) { double y = Math.Sin(x * Math.PI / 180.0); _list1.Add(x, y); } // Generate a blue curve with Plus symbols, LineItem _myCurve1 = myPane.AddCurve("Sin (theta)", _list1, Color.Blue,SymbolType.Plus); // Fill the pane background with a color gradient myPane.Fill = new Fill(Color.White, Color.FromArgb(220, 220, 255), 45F); //Make the MajorGrids of Axes visible myPane.XAxis.MajorGrid.IsVisible = true; myPane.YAxis.MajorGrid.IsVisible = true; // Calculate the Axis Scale Ranges zgc.AxisChange(); } [/sourcecode] So far, this library has been a boon to me as I dont have to reinvent the wheel again. Thanks a ton to ZedGraph guys 🙂

IN-Motion: Motion Simulation Addin for Autodesk Inventor

Posted on by

Update: IN-Motion, a Motion and Dynamic Simulation Addin for Autodesk Inventor has been launched by us. Check out the below video for an Overview

Update: Video tutorials on usage of IN-Motion for Dynamic Simulation of Autodesk Inventor Assemblies.

For the past few months, along with my mentor (Aik-Siong Koh), I have been busy developing Motion Simulation addin for Autodesk Inventor. We have named it IN-Motion. Once we are done with the development, it would be available for Autodesk Inventor users, in the form of an addin. Upon installing IN-Motion, they will be able to simulate an assembly both kinematically and dynamically. The following screencasts show the progress we have achieved so far in this regard and very soon we will be launching IN-Motion.

1) Basic tutorial on getting started with IN-Motion. We start with a blank Inventor assembly and place components and apply constraint. Then we start IN-Motion, set rotation to a Insert Constraint (Revolute Joint) and then simulate the mechanism/assembly. Watch high resolution video at AR-CAD.

2) Tutorial on simulating a four-bar mechanism. This assembly has 2 grounded parts and 3 movable parts, with 4 Insert Constraints. IN-Motion allows us to give rotation to one of the Insert Constraints and then the simulation can be made to see the behavior of the imposed motion. Watch high resolution video at AR-CAD.

3) Tutorial on simulating an Elliptical Trammel. This assembly has 4 components. IN-Motion deals with Planar and Insert Constraints in this case and the simulation takes place for an imposed Rotation on one of the insert constraints. Watch high resolution video at AR-CAD.

4) Tutorial on simulating an Engine. We start with the engine assembly that gets shipped along with Autodesk Inventor. Right now, we are not dealing with the sub-assembly(Piston.iam) parts and constraints. We are considering the sub-assembly as a block/part. Upon user feedback, we may actually extend upon the sub-assembly parts. This is mainly because, a lot of processing takes place in our Motion Solver and the sub-assembly parts(if non-trivial) add up to the CPU load. Watch high resolution video at AR-CAD.

5) Tutorial on Dynamic Simulation of a pendulum in Autodesk Inventor, using IN-Motion. We take the pendulum from Tutorial 1 and instead of giving a rotation, we set the value of Gravitational force for the assembly. IN-Motion then passes the gravity to our Motion solver and the dynamic simulation of the assembly takes place. This example is the simplest form of dynamic simulation and complex assemblies can also be simulated for dynamics. We are working on getting velocity, acceleration and force data at any point in the assembly, in the form of a graph. Watch high resolution video at AR-CAD.

Its been quite a long time since I last blogged. Some of the updates at my end

Autodesk Developer Network Logo

I have become an Autodesk Developer Network (ADN) member.

Secondly, I attended Autodesk Dev Days programme at Bangalore on November 12,2008. I could meetup with Autodesk guys and also Deelip Menezes of Sycode fame. I was lucky to be invited along with Deelip to dinner with Autodesk guys(picture below)

Third and most important update is the progress on IN-Motion. IN-Motion is the Motion Simulation addin we are developing for Autodesk Inventor. I am going to post screencasts on the progress of IN-Motion we have achieved so far and hoping to launch IN-Motion as soon as possible.

Develop Autodesk Inventor Addin Using C# – Part 5

Summary: How to Add extra buttons to already existing Addin Command Bar.

This is in continuation of my earlier posts on Developing Inventor Addins using C# Part1, Part2, Part3 and Part4. In our last screencast, I had explained how to replicate assembly tree view inside our addin command dialog. We go a step further and interact with the opened Assembly document / file.

In this ScreenCast, we mainly deal with How to add another button to our existing addin command bar. By clicking on that button, a form would show up. We use SelectSet method of Inventor to capture user Selections. In screencasts to follow, we would try to explore how InteractionEvents can be used in place of SelectSet.

Upon selecting an ocurrence (Part/ Sub-assembly), the label in our Form is changed to its Display Name. Its not a big deal though, but atleast we are heading in the right direction.

Would love to hear any feedback in the form of comments.

Watch High Resolution Video on AR-CAD

This is in continuation of my earlier posts on Developing Addins for Autodesk Inventor using C# Part1, Part2 and Part3. In this screencast, I have introduced a TreeView component in our Custom Form, which gets displayed upon clicking on our Addin Button. I have also introduced concept of ImageList briefly and how it was coupled together with our TreeView.

We also added a new set of methods/ functions in AssemblyTreeCmdDlg.cs file. The major part of the code has been taken from AssemblyTree Apprentice Server example, that gets shipped with Inventor SDK.

Upon clicking on Submit button (on our Form), Inventor quickly produces a TreeView with all the Parts, Sub-Assemblies in the active assembly file, and also shows the Constraints that each of these parts / sub-assemblies have.

This post is in continuation of my earlier posts on Developing Addins for Inventor using C# part1 and part2. In this screencast / video tutorial, we go a step forward and show a Form / Command Dialog when our Custom Button is clicked in Inventor. The form created is very much basic. Ideally the form should minimize along with Inventor if Inventor is minimized. That part is not taken care of in this screencast. It would be done in coming tutorials.

When our Custom Button is clicked (OnExecute), a form is displayed with a label and a Submit Button. Upon clicking Submit Button, the file name of the active document (opened file) is retrieved from Inventor Application object and updated in the Form.
