Inventor lacks IMPORTANT 2D Sketch Capabilities -

Inventor lacks IMPORTANT 2D Sketch Capabilities -

Introduction:

I just submitted Multiple Ideas that are all related to 2D Sketching. I find a big lack of capability within Inventor's 2D commands. It has driven me crazy since I started using Inventor frequently. It was the first software I ever learned, but then I went into the HVAC Engineering industry and I now regularly use Revit and AutoCAD. This is where most of my knowledge comes from with regard to CAD. I am working on projects within Inventor to design new Invention Ideas. I have fully designed a QuadCopter Airplane, a complex Toolbox, and now I am designing a new cold brew coffee maker.

 

See below for my idea submissions:

 

A. The functionality of some of the "Modify" commands in 2D sketch mode is garbage:

 

 

 

2.  The lack of Dynamic Input on the Modify commands is crushing my efficiency. 

The Breakdown: When I need to copy a circle to a new location that is 10mm directly underneath the original, in AutoCAD or Revit I would normally Copy, select a base point, move my mouse down along the constrained Y-axis, then I would simply type "10" and hit enter to complete the Copy. Now, I have to draw a guiding line going from the base point to the destination, and then execute my Copy command, and then delete the line. I love how Inventor's Dynamic Input works when drawing a line --- just add that system to Moving and Copying. I tried learning about precise input, but I could never figure it out. It just isn't intuitive.

 

Summary:

Look, I love Inventor. It holds a special role in what I do. Its extremely intuitive, easy to learn, and for the most part, you can get anything you want done eventually.

It is really smart sometimes. But the fact is, when you are in 2D sketch mode, it really lacks ability. And this is the most frequently used mode within Inventor. Everything stems from a 2D sketch. Inventor is bottlenecked by the fact that it just isnt as good at 2D sketches as AutoCAD. Even Revit has picked up on some of these things (Mirror suggestion), while Inventor hasn't. The worst part is, Inventor is slower to work in that AutoCAD is. That means that for me to draw a line with the intention of later deleting it, it's going to take me that much longer because of that wasted line. Please just take some 2D CAD notes from AutoCAD and hide the features somewhere within Inventor, for the majority of us who use and know AutoCAD.

Inventor s sketches are parametric environment s. They are almost exactly opposite to AutoCAD drawings.

In AutoCAD, everything stays put. In Inventor, everything is free to move untill YOU fully describe your design intent by fully constraining your sketch.

So, with Inventor I would first create my geometry without worrying about location or size, because it will be free to move until I constrain it anyway.

1. Sketch circle one at the origin (it's important to have at least one fixed point) and enter a diameter.
2. Sketch circle two, roughly to size and approximately in the right location.
3. Add an equal constraint to make the two circles the same size.
4. Add a vertical constraint to align the circles centrepoints verticaly.
4. Add a dimensional constraint to set the distance between the two circles.

Does that help?
