Autocad common questions when commands are "Not working"


Line  - Disappears after starting - You must specify with a left mouse click at least 2 points. Pushing enter after the first point will cancel the line.


2 lines for the price of one - You didn't push enter to finish the line command at the right point. Each left mouse click adds another segment.

Line - after a specified point as per command line - right mouse undo - undoes last segment - can be repeated to original start point of line


Osnaps not appearing - Is Onsnap mode on (F3 function key toggles). Is command line asking for a specified point? 


Erase - Accidental - Whilst it's easy to use grips and then erase, grips don't go when mouse pans/zooms. So you can delete objects off screen.

(Don't be lazy - use the erase command instead - that way you will see all objects to be erased - just remember to push enter when finished)


Zoom Extents results in a tiny or unseen drawing - You have good data and bad data. - Bad data is where you have created an object too far away such as with an offset command which has been given a far to large offset distance.


Undo Zoom extents so that you can see the good data. 

With command line clear (Use escape key if necessary). 

Go right mouse, clipboard, copy with base point

Type 0,0 when prompted for base point

Now select good data objects with a window selection box (Either green or blue), push enter to complete your selection

Now type E, short cut for the erase command, in response to select objects type "all". Then push enter.

You have now deleted both good data and bad data

Now go right mouse, clipboard and paste to original co-ordinates or paste to 0,0.

This will put your good data back in it's correct place.

Zoom extents should now work as normal


Using PDF files in Autocad PDF files can be inserted into an Autocad drawing using the "Insert PDF toolbar icons on the insert ribbon bar

Alternatively we can supply PDF to CAD conversion software. It's currently £195+vat and can save you a lot of time spent tracing over an image



Can't find center point of an arc or a circle - Move cursor over the arc or circle edge, a cross will appear. You can then use the center point.


Fast trim - Type the short cut for Trim which is TR and push enter - then right mouse in the screen area for fast trim. Just trim any trimmable object to trim to next cutting edge


Fast Extend - Same as fast trim - push right mouse 


Offset - specify distance - Can either be a value or 2 points clicked on screen to represent the distance. 

Best rule is type in a distance if you have one, before clicking a point. 


Blocks disappear when inserted - check that the current layer is not turned off or frozen. Has the layer on which the block was created been frozen?


Try zoom extents - can you see your block insertions in the lower left hand corner? If so the block's insertion point has been left at it's default 0,0. You will need to explode the block and redefine it using your original name and a convenient insertion point on the block.


Sizing issues - It could be too large or too small to display. Try inserting the block into a new blank drawing. Go to the A icon, Create a new drawing. Go to bottom right hand of dialogue box, open with no template in metric.  Zoom extents to see your block.  You can check it's size.

Use the Scale command (Short key SC) to scale it to the right size. Scale factor is What distance it is / what distance it should be.


Block references itself


If you are modifying an existing block you should explode it first. The system will only let you have one block name definition.











Copy through clipboard with base point, use 0,0 so that additional content fits

De-select objects in either selection sets or grips - shift + cleft click objects or selection boxes

Delete unused layers etc. with purge PU
