Add()-method in pyautocad

In this blog post, I am going to discuss one of the most important methods in pyautocad i.e. Add(). This method opens up doors for creating a number of document-based objects as per AutoCAD’s Object model. For a more comprehensive […]

Artificially intelligent algorithms for optimization in Python

Following the previous articles on interfaces (+) and (exact) solvers (+) for optimization in Python, in this article, I introduce some packages that provide an easy-to-use “interface” for artificially intelligent algorithms (AIAs) (e.g., heuristics, meta-heuristics, math-heuristics, learn-heuristics, hyper-heuristics, or sim-heuristics). […]

Creating a support vector machine using Gekko in Python

In this blog post I model a support vector machine in Python. Previously, I modeled and solved the quadratic assignment problem (QAP) in Python using Pyomo (+). I described that the “similarity” of two facilities could be a reason for […]

Solved: ‘Call was rejected by callee’ in pyautocad

In this blog post, I will discuss an error that occurs while automating tasks in AutoCAD using the pythoncom module.- The pythoncom module is a AutoCAD automatization module in Python. Also, I will provide a solution for the same. The […]

Quadratic assignment problem with Pyomo in Python

No matter if it is the assignment of departments to empty rooms in a building, machines to manufacturing cells, factories to geographical regions, products to racks in a warehouse, sensors to devices, edge computers inside the internet of things network, […]

Flow shop scheduling with PuLP in Python

In previous articles, I modeled and solved a single machine scheduling problem. What if we have two resources that operate in a pre-determined sequence (but not in parallel) to process a set of similar jobs? The so-called “flow shop” scheduling […]

Pricing with linear demand function using Gekko in Python

How can we decide on a product or service price using observed data over time? For example, a retailer may have changed the price for a specific product in multiple time slots of a week, tested the demanded quantity (sales) […]

Python namespaces: Local, nonlocal and global assignments

Together with my co-authors I am proud to see that we have achieved a substantial amount of coding examples and use cases on this blog. Our contribution related to Python are growing. For this reason I want to keep publishing […]

Singly-linked lists in Python

In this blog post I will discuss one of the basic types of linked lists i.e. singly-linked lists. This is one of the important and simple data structure types. Furthermore, this is a data structure that can be defined by […]

Tree data structure for AutoCAD objects using pyautocad (Python)

In one of my previous blog posts, I discussed how we can use lists and dictionaries for storing AutoCAD objects created. In this post I want to introduce some more efficient data structures that we can use for organizing AutoCAD […]

Commenting code in Python

This post provides a quick tutorial on how to comment Python code. There are three ways of commenting Python code: Single-line comments Multi-line comments Docstring comments Single-line comments In Python, single-line comments can be implemented with the # operator. This […]

Extending AutoCAD objects with pyautocad in Python

In my previous post I discussed and demonstrated how to check for intersecting AutoCAD objects with pyautocad in Python. In this post I want to do something similar yet different: I want to show how you can extend AutoCAD objects […]

Intersecting objects in AutoCAD using pyautocad (Python)

In this blog post I will be discussing the IntersectWith method for dealing with intersecting objects in AutoCAD. The method can be used for identifying intersecting AutoCAD objects. It can also be used in combination with object extensions, i.e. when […]

Using Python lists and dictionaries to work with AutoCAD objects with pyautocad

Now that we have understood the basic usage of different pyautocad methods and objects from our previous blog posts we need to learn how to work with those more systematically and in an efficient way. This blog post brings you […]

Raster image object in AutoCAD with pyautocad (Python)

While working with AutoCAD, sometimes we need to insert external objects such as images. That is why in this blog post we will discuss how to insert an image in a AutoCAD template using the pyautocad module. Setting up environment […]
