Recently I just started using C# to develop something to work with Solidworks.


Someone please help me to get started...


Below just the code to change a dimension in a opened document(I added two COM reference just as they instructed here):



using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;


namespace ccccc


    public partial class Form1 : Form


        public Form1()





        private void button1_Click(object sender, EventArgs e)


            SldWorks.SldWorks swApp;


            swApp = new SldWorks.SldWorks();


            SldWorks.ModelDoc2 Part;


            Part = swApp.ActivateDoc;   //Cannot convert Object

            Part.Parameter("D1@Sketch1").Systemvalue = 0.1;




            //swApp = null;  






However, Visual Studio complain about the code in red colour?!!


Please help how to write that part please... I just need to assign opened document to it, but it refuse to work!
