Let s talk about CAD2009 what practical changes have come from the design institute.

Thank you, friend, I am Dream Street, and I have the opportunity to communicate with you!!

If you have any questions, you can communicate together**!!

1. Open the Options dialog box;

2. Select the display label and click on the "Color" option;

Hello, I have been using CAD for 8 years.

TENGEN CAD, ZWCAD, etc. are secondary development programs of CAD. For CAD beginners, learn AutoCAD first, and then use the secondary development program directly. There are many versions of AutoCAD, etc., my personal opinion is that the old version of the software is generally more mature and stable, so it is recommended that you use the 2004 version.

And if you use the old version, the later diagram can be opened in the new version of the software, and the new version is not easy to open in the old version.

The second is that the new version of the software has not changed much in terms of practical functions, but the name has changed.

For beginners, the main thing is real combat experience. This is also easy to do, you take a few pictures, according to the above description, make sure you 4 pictures to draw down, you will basically be, and then it is the process of proficiency. If you don't know something, you can ask me, practice for 3 hours a day, less than 4 days, you can't learn to cut me.

But brother, I have to tell you the truth, learning CAD is attached to some kind of profession, right? So you have to choose a good major first, whether it is machinery, construction, or molding. The first two are enough to use CAD, and it is best to use UG to learn molds.

Of course, you just need to be a draftsman. 25355 hope it helps you!

Right-click on a black background and there is an option at the bottom.

Go to the Display tab.

There's a color in there.

You can change it.

Tools - Options - Display - Colors in the menu.

That's too easy, in the drop-down menu in the top left corner of the CAD, click on the option at the bottom, go in and there's a sketch option, click on the color, go in, have a uniform background color, and change the settings to black.

1. In the text toolbar, select and then select the annotation text that needs to be modified, and enter the new content.

2. You can also use the command to modify, enter the command ed enter, and the same operation is also used.

3. If you often use this function, you can also click to modify a simple shortcut key, click Tools-Custom-Program Parameters, find ed ed and then modify it to the required shortcut key, and save the notepad.

Get the attribute bar out and replace it with text.

Enter the ed text command to modify.

1.Click the Tools button on the interface and drop down to select an option.

<>2.A dialog box appears, click on Display, find the crosshairs size, and control the crosshairs size by adjusting the blocks.

You can change it in the crosshairs, and I 359578763 if there's something

Enter the command op and the options will come out.

Let's take a closer look at it in "Options".

In the installation folder, he was sent to find him and found him without leaking the modification, if there is no modification, I will send you a copy!

In this case, the request made by the owner (Party A) is generally unreasonable from a technical point of view. or violates the relevant national building regulations, codes and regulations. Or the use of backward technology, technology, materials, so that the designer is afraid of losing face in the industry.

So only the drawings are produced to meet the requirements of the owners. Failure to sign indicates that it is not the opinion of the designer.

It should be noted that if the drawing is not signed and has no legal effect, it is invalid and changed, and it is strictly impossible to pass the acceptance.

If it is not in violation of the relevant national building regulations, norms and regulations, it can be negotiated with the designer to issue the owner's reasons for requesting such a change and to admit that it has nothing to do with the designer. If it is in violation of the relevant national building regulations, regulations, then do not ask people to sign, it is a great face to be able to produce drawings, and once there is something, the designer will be responsible if he does not sign.

Under normal circumstances, even if the owner has good professionals, it is not as comprehensive and in-depth as the design institute to grasp the national norms and the current situation and development of the industry, so it is necessary to listen to the opinions of the design unit, explain the purpose to be achieved, and ask the designer to come up with ideas, which can not only solve the problem but also make both parties passable.

By the way, I have worked in the design department, but most of the time I am in the owner's unit, and I know a little about both sides, and I hope that the suggestions put forward can be used as a reference.

Most of the time the requirements put forward by Party A are unreasonable and force the designer to make changes, so the responsibility is pushed to the designer, and the designer is not stupid. The designer does not pay the design fee, which is bad, and the stomach is bad. How much does it cost to design?

In the event of an accident, the design fee will be compensated, and it will be posted upside down. Party A, a little conscience! It's interesting enough to give Party A a white picture.

Communicate with the design institute and explain the reason for the change. If it is really illegal or the economic and technical comparison is unreasonable, then the design institute is right to disagree with the change; Party A does not ask for changes, and only the drawings are not signed. It is best to communicate further and make it clear that the general design institute will not get along with Party A.

The reason is that Party A proposes that the design institute only produces drawings but does not sign and seal, and does not make changes. This sentence means that Party A entrusts Party B only to produce drawings without qualifications, so the design fee is charged for white drawings, and of course it is not stamped.
