But again, picking the erase command first and then the entities sends a clearer message with a very noticeable difference in performance when working with large selections. An extension of this is to get out of the habit of using the Delete key for erasing entities. This instruction is much clearer and skips out a lot that we’re not interested in. This is vague, so AutoCAD® has to prepare for anything. However by invoking the command first and making a selection afterwards you’re saying “I only care about performing this action – these are the entities I want to perform it on”. By selecting first you’re saying to AutoCAD® “Here are some entities that I am interested in – prepare them for me to use in any way”. This sends a clearer instruction to AutoCAD®, and it is dealt with more quickly than if we make the selection first. Make sure you select commands before you make a selection. There are ways of working that allow us to drastically reduce the frequency of AutoCAD® freezing when working with a large selection. The time that this takes is proportional with the amount of things selected, so you can see that simply selecting objects can be the cause of AutoCAD® freezing. So, if for example you have the properties window on your screen anywhere, even if it is docked with the auto-hide feature enabled, all the data in the properties window needs to be updated with correct information. When a selection is made, any on screen information that relates to your active selection needs to be updated otherwise you’ll be working from incorrect information. This can sometimes leave us gazing at an hourglass thinking “I didn’t ask you to do anything! Why are you freezing on me!?”. Odd as this may seem, there is a reason for it. What can sometimes be unexpected is when AutoCAD® freezes when we have merely selected the objects without doing anything to them. The first and most obvious reason for AutoCAD® freezing is when we do things to a very large selection. It often will shave several Megabytes from the file size.How many times have you been working in AutoCAD®, and then suddenly it freezes on you? Panic sets in, as you try to remember the last time you saved… You wait… and wait… and… thankfully AutoCAD® un-freezes, this time…īut what actually is the cause of AutoCAD® freezing? It depends – there are many potential reasons for AutoCAD® freezing, but some can be avoided completely with a little understanding of what’s actually happening. Look at the file size before and after the Wblocking. That block would not be selected if you used the Window selection method and did not include that speck.īy the way, this Wblock method is just a great tool for really cleaning up any drawing. Crossing is the safer method in case there's an oddball block with a hard-to-see speck way off in space somewhere. You probably should select by Window or Crossing or WindowPoly or CrossingPoly, (not All or Ctrl+A), to make sure only the visible things are saved to the new drawing. Just hope the paperspace objects were not the corrupt part of the drawing. Or you can Copy and Paste from old drawing to new drawing. If you need the paperspace objects, you can use Design Center to drag the layout tabs back into the new file from the old file.
Only the modelspace entities you select will be wblocked.
Be aware that Wblocking by the selection method will not include any paperspace entities.
