Geometrical Constraints
(OP)
When creating a Sketch, is it possible to make use of Geometrical Constraint like "Equal Length" or "Equal Radius" ? (this is a function in UG)
Or is the only way of doiing this in CATIA is to us the Formula Function.
Thanks

double click the value and type to dimension field = and select the dimension You want.
That should do the job.

What I want to know is Geometrical Constraints, not Formulas.

When you create your circle, you can rightclick on the other circle and get same radius but it won't be link (open HMR if you want).

Hope this helps for the radius.

you set equivalent dimensions for Rad A, Rab B, Rad C.
Then you can change the one you want they will all change.
If you set regular relations rad A = rad B and rad B= rad C, then you can change only C.

As itsmyjob has alread pointed out, there are COPY LENGTH
and COPY RADIUS for you to pick up when you're creating your line or circle respectively. While creating your line/circle, move your cursor to another line/circle, MB3+Parameters+Copy Length/Radius.
Or supposing you've already created a number of cirlces/lines, and you've also assigned a length/radius constraint to ONE of the line/circle. Then you may try Ctrl+C the contraints, next Ctrl+V on those lines/circles. As a result, those "slaves" will subsequently follow the value of the "master".
Of course, in all cases, no link!!

i have catia v5 drawing of version R13. but these drawings do not open in earlier version like R7.
please help

That being said, there is a "DownwardCompatibility" utility that can migrate CATParts from one version down to other versions. For CATParts, the result is a Volumetric Solid (no history).
Unfortunately, all other V5 Documents are not able to be migrated downward, including CATDrawings. The only option available for these is to export them to DXF or IGES and re-import them at the lower level.
