I can't see anything in Sketch

[akhtar07]

Hello Guys,

I need a help with a simple problem as far as i think.

I open a DXF file and copy the contents or 2D geometry from the drawing and paste it in the Model Sketch.

Doing so, everything is pasted but i can't really see it. When i exit the sketch, lines and points are there. But when I double click the sketch everything vanishes again.

Can someone tell me what's going on and how to fix it?

I would really appreciate ur help guys.

Warm regards,
Akhtar Aziz

right click on the sketch ( from tree) and click Define in work object .
may this will solve your problem.

I already tried that buh it is only working from coming out of the sketch.

I can't see things when I am inside the sketch.

Warm regards,

Try to use "fit all in" and look in "no show" space for the geometry. Also, make sure the geometry is not hidden in the tree.

Another guess at what might be causing the blank sketch problem: you have the "display current body only" option turned on. To show all the bodies: look at the bottom menu for a little red/orange rectangle icon, and click on it to change the icon to 3 blue rectangles. (red/orange icon means display current body/set only, and blue icon means display all bodies & sets)

Also, you can verify the sketch contains geometry by expanding the geometry branch of the Sketch in the tree.

This happens to us all the time when bringing in DXF lettering that will be used on a part surface.
Here is what we do:
1. Cut and paste DXF into sketch
2. Immediately select "Fix Together". DXF geometry will highlight, and place green paperclip to geometry.
Note: the reason DXF is not seen (in our process) is because it's black, against a black background.
3. Move geometry to area of use (part surface to apply to) and it will be visible, I.E; black letters against part surface color.
We use this process because it makes it easy to place the DXF into desired position.

You can also: select all DXF geometry via cursor or tree and change graphic properties to a visible color.
or
change the color of the DXF in the drawing prior to bringing into the sketch.

Guys,

I have tried everything:

1. Changed the color
2. Fit all and look around
3. View in hidden background
4. Make sure nothing is hidden
5. Check if the sketch contains lines and points
6. Toggle between Blue and Orange sets

Nothing is working for me... anyways I really don't make any changes in the sketch, so it is not stopping my work but we need to come up with the solution.

Do You have a Visualization filter set?
Tool>Visualization Filters (should be set to all visible).
Could you post a catpart with the sketch?

copy and paste the sketch in a new file.

can you also just remove all geometry from sketch but few lines and share the file with us?

I imported the DXF into a Drawing selected it all, then copied and pasted into a sketch.
No Problems.
See attached.

This is what I see in sketch:

outside sketch:

all but one line in the sketch are blue (0,0,255) : (guess I did not copy all dxf geometry, I m missing some frame black lines)

what color is you background?

all but this:

is on layer 0

do you have a filter applied?

chose all visible to remove all filter.


Also 15000 elements in sketch might be too much for some video card (who knows)
copy small area from DXF into sketch and see if you have same result or not

Rickyt and itsmyjob.. thank you guys..

it was due to the Visualization Filter, i didn't notice at the first.

Now i can see, select and modify the sketch

Thanks a lot everyone...

BTW how to set visualization "to visible all" by default ?

Warm regards,

[itsmyjob]

it should be, if not 'clean' your CATSettings

FYI
There is one setting on whether the filter is applied to all or current documents.

I have seen filters accidentally applied by opening Catia v4 models.
Once you open a V4 model, v5 will apply the filter that was saved in the V4 .model file.
Now every time you open a v5 file, this filter is applied until you turn it off or delete it.
