Z axis messed up!!

[mata]

I don’t make so complex things, just 2D general detail dwgs. Sometimes I need to add a perspective views for the objects I make, then I use basic 3D tools to construct these objects, but when I do 3D there are something that drive me crazy, it’s that some lines, text, etc. go back or front on Z axis. what settings I should fix? What I’m doing wrong?

I know I probably didn’t explain good enough my problem so I attaching some JPG you can see on pic#1 a conventional dwg I use to do.. all looks good.. a flat 2D view; but take a look on pic#2 when I go to a different view Z axis is all messed up!!

It looks to me as though you've been using your object snaps to snap to objects at different Z elevations. In plan, you won't notice this. I recommend that you read up on UCS. I notice that your model is effetively lying on its side relative to the WCS and this makes orientation difficult. Consider building your models in model space and then putting your views together in a layout, in paper space.

Yes your problems is UCS related, the objects looked messed up because they have create on different XY planes..

Take Cadtutor's advice and read up on UCS.

thanks for your help, i went for a glanze at UCS help and will go more deep on it later.. I just would like to try explain better my problem; it also happend when I just do 2D lines. for example: I just making a simple square in a new dwg. I'm laying 4 simple lines starting anywhere on model space, then to end to end and so, also I'm putting a circle at right side. now I go to isometric view... and here is again.. one of the lines is somewhere back on Z.. also the circle center went back!!
this is actually my big bother, 99% of my drafting is always flat, but when I need to pedit there is always some lines or arcs that arent right on Z. or if I just get done a dwg. with dims, text, hatchs.etc it looks fine in flat but if I go to iso or top view some elemets are moved in Z..
there are some setting I should fix in order to cad doesnt mess with Z axis?

Type in -CH or CHANGE. Select object, then type P for property. After that, type in E for Elevation. Type in 0. What this will do is to change all objects in Z value to 0. Unfortunately this one doesn't flatten line with different Z value.

UCS can be confusing and difficult to grasp.

Everything you draw is on planes that pass through the origin point (unless you use snap points).

Turning the grid on will show you the current drawing plane.

Consider carefully where the origin is.

Use the move command to reposition drawn features.
