Difficulty in selecting sketch entities in Creo

[ML_11353167]

I'm working in Creo Parametric version 11.0.1.0.

When in sketch mode and selecting entities for adding dimensions, I hover over the entity until it highlights, but when I click the entity often does not get selected. I thought there might be a config parameter that affects the sensitivity of sketch entity selection, but I wasn't able to identify one.

Can you check your computer's scaling setting? I've seen this issue occur when your scaling factor is set to something other than 100%. You can access the scaling settings by right clicking on your desktop and choosing Display Settings. Set it to 100% and try again.

Thanks for your reply. This setting was already at 100% for my monitors.

Could be a graphics issue.  In 7.0 and Creo+ (running Creo12.0) I get instant highlighting and selection.

Is it the same with the display set to wireframe?

You could also try setting config graphics to win32_gdi to disable the video card.  If this helps, you may need to use an updated driver (the latest is not always the best).

[ML_11353167]

Setting the display to wireframe did not change this behavior.

How do you set config graphics to win32_gdi?

[kdirth]

In your default work directory, there should be a file named config.pro.  Open it in a text editor and add the line graphics win32_gdi

[ML_11353167]

I tried adding this parameter as you suggested. It definitely had a noticeable affect on the graphics, but not on the original problem.

If that option had solved your problem, it would have meant your issue is specifically a graphics card issue.

Since it didn't, your problem is elsewhere.

Make sure you remove the option, it will destroy your overall system performance.

[ML_11353167]

Yes, I noticed! The option has been removed.

There is an option in the config.pro called :

pick_aperture_radius 

If this is set in any of your configs, it may make select more difficult. But honestly, I suspect it is either of the other response, graphics card or scaling.

[ML_11353167]

Thanks for your reply. This option was not already set, and setting it to its default of 7 did not seem to make things any better or worse.

What is the selection filter set to when you are having difficulty in sketch mode? It should be set to "all sketcher" but it is possible that it may not be.

[ML_11353167]

This problem typically happens when trying to apply dimensions or reference dimensions, at which point the selection filter is set to "All."

[StephenW]

Is this in a large assembly? I know that once my assemblies get to a good size, selection begins to get worse. Most prominently in large assembly drawings, but in modeling also. Even worse when surface models are involved.

[ML_11353167]

No, this happens in sketch mode when modelling parts - even simple parts. I've seen what you're referring to as well, but that usually appears as a lag in highlighting or selecting entities. What I'm experiencing is no lag in highlighting but failure to select. I should also emphasize that this is an intermittent and so far unpredictable problem.

[StephenW]

Yes, agreed. Lag is correct for large assy's.

Intermittent and unpredictable is horrible. Hard to figure out what the issue is.
