how to create new plane in solid works

If you don't know this, than where are your models from?

insert - reference geometry - plane.

But perhaps it is better to "explore" all the commands and find out yourself.
Also the use of HELP can be very helpful.

But if it is very important to "create new things and designs"....perhaps it is wise to get professional help (school, course, or buy a solidworks book)
If you do not know how to add a new plane (one of the basics), than you will get into more problems.......

I have looked at the model FRONT WHEEL ASSEMBLE
How you were able to do this without the basic knowledge of solidworks....this is a miracle...please explain to me how you were able to produce this model without adding new planes......

now i got the short cut key for generating the new plane
it is just click the ctrl and pull the requried plane to required length and dimensions and thank you for giving a lot of knowledge regarding this

Ctrl + drag an existing plane to create a new plane that is offset from the existing plane.
