With so many Autodesk product experts, writers, authors, and blogs out there it has always been a pleasure to publish a guest post from someone. It helps the guest author get more attention and also shares some valuable knowledge with the readers of the Between the Lines blog, a win – win for everyone in my book. Perhaps you are looking for a job and want exposure and to be noticed by a large audience or perhaps a link to your blog and all the SEO goodness that comes from that. The only thing I ask is the topics be Autodesk related and exclusive. If you would like to submit a guest post please Email Me for details and consideration.

Do you need to create hatched areas in AutoCAD using Circles, Arcs or Splines? Find out how with this quick tip.

OK, my title is a bit cheeky. Of course, you can’t create AutoCAD hatches with Circles, Arcs and Splines.

But I can show you another technique that you could use to get a great result.

Did you know that AutoCAD’s ‘CLIP’ command can be used to clip Blocks?

We can use this feature of AutoCAD to create a re-usable pattern that will act in place of a Hatch.

To use this method we will need:

• An AutoCAD Block which will represent our hatch.
• A Polyline as the Clipping Boundary.

Tip: The polyline can be closed or open, but it must contain straight line segments only.

Firing up the ‘CLIP’ command

Button

You will find the CLIP command on the ‘Insert’ tab on the ‘Reference’ Panel.

Tip: If you are using AutoCAD in ‘Classic’ Mode you can use:
Modify Menu > Clip > XRef

You can also start the CLIP command by typing ‘CLIP’ at the command line.

Pick a Block to Clip

AutoCAD will ask us to select an object to be clipped:

Command: CLIP
Select Object to clip:

In this case we will choose our Block.

AutoCAD will ask us for a clipping option:

Enter clipping option
[ON/OFF/Clipdepth/Delete/generate Polyline/New boundary] <New>:

In this case we will choose ‘New’ to create a new clipping boundary.

Pick a Boundary

AutoCAD will ask you to specify a clipping boundary:

Specify clipping boundary or select invert option:
[Select polyline/Polygonal/Rectangular/Invert clip] <Rectangular>:

In this case we will choose ‘Select Polyline’ and pick the Polyline that we wish to use as our clipping boundary.

The Result!

The Block is clipped to the Polyline that we gave it.

Note: The Block is not permanently trimmed, and can be used again elsewhere in the drawing.

The clipping boundary can be adjusted at anytime by Grip editing or using the ‘CLIP’ command again to define a new boundary.

An Extra tip for AutoCAD 2012

AutoCAD 2012’s new Dynamic Array objects behave like Blocks. They can also be trimmed with the ‘CLIP’ command.

I hope that you enjoyed this quick explanation of Block clipping. Do you use Clipped Blocks in your workflow? Can you think of any situations where this technique would help you?
