A quick post to highlight that AutoCAD has a lot a “hidden” settings that most people (including me) don’t use or even know about.
Take for instance Match Properties, this actually has a selective settings box so that only some of the properties from the source object are matched!
Note that when Match Properties is clicked and the source object is selected AutoCAD lists the current settings under “Current Active Settings”, usually this is everything, however you can type S (or click settings in 2013 and above) and you will be presented with the dialog to turn off (or on) various properties to copy.
Further to my previous post regarding renaming AecCore.crx, it has been suggested that this could break other things. A slightly “better” patch would be to copy the AecCore.crx from the 2013 install and place it into the 2014 folder. This does work and no visible breakage yet!
Our CAD support people have suggested that this patch is a reasonable temporary solution though they say if an update from AutoDesk arrives then you will need to revert back to the 2014 version of the AecCore.crx file before installing the update.
Also the CAD support people looking at this flickering issue with AutoDesk at the moment and I will let you know the outcome of that.
It appears that changing AecCore.crx in C:Program FilesAutodeskAutoCAD LT 2014 to AecCore.crx.old or similar (in order to stop it working) fixes the flickering symptoms, making the program usable again. However this will most likely break something else as this file is an object enabler. The underlying issue appears to be with the new mapping feature (which makes sense as there is a greyed out map pin next to unrecognised when the bar flickers) and that is not working properly.
We all wait now for a Service Pack or Hot Fix for this from AutoDesk. Please check out this page regularly to see if the hot fix or service has been posted. I will update my blog when it arrives to see if it fixes the issue!
As previously mentioned we updated the drivers to the latest ATI drivers for the Firepro and that seemed to stop the flickering. It however came back today. A restart of AutoCAD stopped it from flickering which is better than before as it was all the time.
On this forum post it has been suggested that network file access might be the issue. However its early days in troubleshooting!
A colleague of mine had dropped in some blocks from an external source and found that they had two layers and wanted only one. They wanted to move all objects on one layer to another within the blocks.
Normally I would go about this, if there were no blocks involved, by using QSELECT. Then select the desired layer in the Ribbon and PURGE out the unused layer.
However as they are in blocks this does not work as the selection ignores the lines in blocks and just selects the blocks themselves. As we were after only specific lines in these blocks I was faced with exploding them all or some clever LISP.
However I discovered two commands that would not require LISP or lots of work! If you don’t want the layer LAYDEL should do the trick but the one that was really awesome was LAYMRG. This merged the two layers and purged out the unused one and kept all the blocks intact!
This can be found on the ribbon in the following location:
One of colleagues today noted that today he had annoying boxes. When I looked at his screen he had something like this.
These strange annoying boxes are constraints, part of AutoCAD’s parametric system, found under the Parametric Tab on the ribbon (strangely).
In order to use constraints you need to click the INFER constraints button on the bottom left of the status bar. This allows objects drawn in this mode to have the Parametric constraints. This button looks like this
Or this, depending on whether you use icons or not.
Once on you can draw your objects to be constrained. Here I have drawn a rectangle and a polyline. If I move the polyline the rectangle will deform as the polyline and the rectangle are linked or constrained together.
If you do not want this constrain feature on this object anymore you can click on the object and then delete constraints on the ribbon.
Once removed the object returns to a plain old rectangle polyline.
Remember to turn off the INFER constraints button before drawing anything else as all items drawn will have this parametric capability.
So you got a nice shiny new machine, an AutoDesk certified graphics card and you’ve just installed the latest version of AutoCAD. All is great, you have lots of new features to help you productivity and you are steaming along. Then you insert an image and this image has a white background. Then your world falls apart. You can no longer see your cross hairs.
You have white cross hairs on a white background.
Don’t worry this problem can be sorted by turning off 3D acceleration. For some unknown reason AutoCAD does not have dynamic cursor colour when 3D acceleration is on!
Type 3DCONFIG in the command line, click “Manual Tune” and uncheck “Enable Hardware Acceleration”. The dynamic cursor colour now works.
Once you have undertaken the task needing the dynamic cursor colour feature you will probably want turn the acceleration back on.
One of my colleagues asked today, how do I get those paper-space dimensions to work? As I tend to dimension in Model space (I need to research associative dimensions) on differing layers per style I never see the need to use paperspace dimensions.
So after a quick perusal of the Dimension style box, there is a check box to make the style to scale to paperspace. Cunningly called “Scale dimensions to layout”!
However strangely this did not work. After further searching I found that if the paperspace dimension is different when snapped to differing scale viewports then the DIMASSOC variable is most likely to be set to 1. Set it to 2. Then all will be good.
A slight tangent on my usual posts, but today I noticed that I had a 2nd hard drive in my Windows Explorer that I knew did not exist. This phantom drive turns out to be a mapped drive for AutoDesk Cloud Sync (360)! I think this came from a Beta version of AutoCAD that I have now uninstalled but my AutoCAD 2013 is still using Cloud Sync! I had no idea this was even running. Very annoying. Its been syncing data that I didn’t even want to be copied to the cloud.
This article showed me that I could find out what the Phantom drive was by running “SUBST” from the command line (CMD.EXE) in Windows 7. The results of this were as follows: (xxxx indicates personal info removed)
Z:: => C:UsersxxxxAppDataLocalAutodeskAutodesk SyncCloudxxxx@xxx.com
That means, Z drive is actually a folder which is my AutoDesk sync folder. Hence the hard drives were identical in properties. Confusing.
Solution: Sign out of Autodesk 360. Drive and syncing stop. Awesome!
