Tweaking Repair Tool

[Marguerite Gilbeau]

Tryingto fix a system that is currently infected is obviously a very bad idea and can make things worse. An infection can hijack a machine and keep part of the repairs from running correctly. Since only part of a repair will work the other part that failed could end up causing problems. Rule of thumb before working on a system is to make sure it is clean. Even if you think your system is clean doing a scan before hand is a good idea.

Doing a check disk on the hard drive is a good idea. This will have Windows check the file system on the drive fixing any problem it finds. Corrupt files can break a lot of things, including the repairs. So making sure the file system is good is a must.

The built in Windows system file checker is a tool that checks that the Windows files are intact, the correct versions and not corrupted. This is a good idea to do before doing repairs as if a file is corrupt and we try a repair that needs that file then the repair will fail.

Doing a system restore point is a great idea to do before doing any repairs. If any unforeseen problems happen after any repair than a system restore can put the system back to the way it was before the repairs. This is highly recommended.

Tweaking.com Windows Repair is a small, portable and free all-in-one repair tool designed to help you fix common Windows problems. Dial-a-Fix used to be a great tool for this task but it does not work on Windows 7 and has not been updated for years. Windows Repair is a great alternative.

I have used this on several occasions for the worst computers, only. It does well with Vista and 7. I do have a problem with the SVCHOST memory error. I tried several known fixes with no luck (Sorry I do not have exact details as I have stopped using this on XP). I always use the newest version and run chkdsk and sfc as always before, but still had this problem on most xp systems. I even tried to use it again last week. I tried all modes with the same results. I just reimage from my backup and avoid this tool or system restore it back if I actually created a restore point. :) It does work very well with vista and 7.

The utilities and fixes built into ADWCleaner are not intended to be comprehensive and I'm sure they don't want to risk including anything that might be hazardous to any users' systems if used improperly and that may be the case with some of these more advanced Windows system component fixes, though I am far from an expert on the subject.

@exile360 the tweaking.com repair MSI tool and all others tweaking tools are no longer available because it is no longer updated . for most recent version of all tweaking tools are included in tweaking window repair tool (all-in-on)

If you were hit by malware or adware and have cleansed your system with AdwCleaner, your computer might still have some residual issues or might behave erratically. Then you are advised to use the 'Basic Repair Actions'.

Since Malwarebytes has decided to offer some 'Basic Repair Actions' (and not all that are possible), you might end up with a visit to the forum asking for assistance. There they will probably advise you to download and run [some other program], which essentially means that AdwCleaner has a sub-par set of 'Basic Repair Actions'.

The repair routines which have been public/common knowledge for years (most of the fixes in Tweaking.com's tools are nothing new/original; they just compiled mostly known fixes over time into what eventually became their repair tool which is why I also linked directly to the original articles/tutorials and MS support topics as well which describe each fix in great detail such that an individual could easily write a batch script to perform the fix routines (I have a folder full of such scripts/tools which I've created, developed and compiled over the years for my own uses). I just needed references to clearly indicate precisely what each fix/repair would require to make it easier on the Developers if they did choose to implement any of the requested fixes rather than making them do all the research.

The geometry power tools are located on the Tree View window under the blue geometry tab. In many cases, a model will fail to mesh because of problems with the geometry. Since the range of geometry problems is so wide, and because these problems can be hard to diagnose, the Geometry Power Tool has several built-in tools designed to analyze and repair these problems. The Geometry Repair Tool analyzes geometry for small angles, overlap, small features, bad geometry definition, blend surfaces, close loops, or mergeable entities that may affect meshing capability. It also contains a powerful toolkit of geometry modification methods to fix these problems. All of the common geometry clean-up tools are now in one place on the GUI menu. In addition, there is a window that lists results from geometry analysis in a tree format, making it easier to find, diagnose, and solve geometry problems. And Cubit will save your settings, so you can run the same diagnostic tests each time you use the geometry power tools.

Bad Angle Upper/Lower Bounds - The bad angle upper/lower bounds are tolerances set by the user to determine the definition of small or large angles. The default values are set at 350 degrees for the large angle and 10 degrees for the small angle. These values are used to test for angles between curves, surfaces, and at tangential intersections.

Tangential Intersection - A tangential intersection is formed when two parallel surfaces share an edge and have a 180 degree angle between them. The tangential intersection test is looking for the condition where two surfaces that meet tangentially share a common edge, and each of the surfaces has another edge which resides on a third face and forms a small angle as shown in the following example. Surface 1 and Surface 2 are tangential to each other and share a common edge. Both Surface 1 and 2 have another edge which resides on Surface 3 and forms a small angle at the vertex common to all three surfaces.

Mergeable Entities Check - As it suggests, this test is looking for entities that overlap and that can be merged. Pressing the "Merge all" button on the Power Tools will automatically merge all entities flagged by the merge test.

Overlap Check - The overlap tests look for geometry that are either overlapping or coincident (exactly on top of each other). Keep in mind that some of these problems may disappear with imprinting and merging.

Small Features Check - Small features may be necessary and desirable in a model, but many times they are the result of poor geometry translation or import, or they may just not be important to the analysis. The small features tests look for small curves, small surfaces, and small volumes. These tests rely on the user-defined short edge length parameter. Small curves, including zero-length curves such as hardpoints, are compared directly against the defined parameter, and flagged if they less than or equal to the given parameter. Small surfaces and volumes, on the other hand, are compared against their hydraulic radius. For surfaces the hydraulic radius is 4*surface_area/perimeter. For volumes the hydraulic radius is 6*volume/surface_area.

Bad Geometry Definition Check - Cubit uses third party libraries, such as ACIS from Spatial, Inc. for much of its geometric modeling capabilities. The bad geometry definition check calls internal validation routines in these libraries, when available, to check for errors in geometry definition. If the third party library does not provide validation capabilities, this check will not return anything. Note: ACIS is a trademark of Spatial.

Blend Surface Check - A blend surface is a transition surface between two orthogonal planes, such as a fillet. The blend surface check identifies the surfaces which meet this criterion. Many times these surfaces are candidates for the split surface command or the remove surface command. The split surface command allows you to split these blend surfaces into two surfaces, making it easier to mesh the volume. The remove surface command removes the surface and extends the adjoining surfaces until they intersect.

Close Loops Check - Close loops (pronounced KLOS, not KLOZ) are two loops on a single surface for which the shortest distance between loops is less than a user specified tolerance. The tolerance for close loops is the square of the shortest edge length parameter. Close loops are common around holes and fillets, and are usually found where one loop is entirely within the other loop. These surfaces are often candidates for removal, or tweaking.

Note: Pressing most of the geometry tool buttons on the panel will only bring up applicable command panels on the Control Panel. You must press the Apply button on the Control Panel to execute the command.

The split surface tool is used to split a surface into two surfaces. This is useful for blend surfaces, for example, where splitting a surface may facilitate sweeping. To select a surface for splitting, click on the surface in the tree view. To select multiple surfaces in the window, hold the CTRL key* while selecting surfaces (surfaces must be attached to each other). Then press the split surface button to bring up the Control Panel window with the ids of selected surfaces in the text input window. The split surface menu is located on the Control Panel under Geometry-Surface-Modify. You must press the Apply button for the command to be executed. You can also bring up the Split Surface menu by selecting surfaces in the tree view and selecting Split from the right click menu.

The healing function in Cubit is used to improve ACIS geometry that has been corrupted during file import due to differences in tolerances, or inherent limitations in the parent system. These errors may include: geometric errors in entities, gaps between entities, and the absence of connectivity information (topology). To heal a volume, select the volume in the geometry repair tree view. Then press the heal button. You may also press the heal button without a geometry selected in the window, and enter it later. The Control Panel window will come up under the Geometry-Volume-Modify option with the selected volume id highlighted. If no entity is selected, or if another entity type is selected, the input window will be blank. You can also open the healing control panel by selecting Heal from the right click menu in the geometry power tools window.
