questions from neophyte

[wally4192]

Good morning to all,

I'm new for the use of catia and I have a couple of questions, I hope to ask you in the appropriate section!

1) Can I use, as in pro/e, part of geometry, for example a solid edge, as a reference to delimit a new geometry in a new sketch? to understand, the cursor goes to bind to the extreme of the selected edge as reference, if possible?

2) using the 'loft' command I realized I had some difficulties

Hi.

1) Of course it is possible:

command projects elements 3d (iconcine con prisma e freccina down on a floor, or menu-iser-operation-geometria 3d), select a edge, a point or a face that will be projected on the floor of the sketch and can be used. (naturally in construction or standard mode depending on how you need it)

3d intersection command (in its drop-down menu), performs a section of the element, according to the sketch plan and project it.

command projects edges of the 3d shape, in the case of ball or tube etc. project the maximum contour of the selected object

wanting it is not even necessary to project the reference entity, but you can first create the geometry on the sketch and then insert the bond by selecting the edge, point or face of the reference. the same applies to the offset, you can simply select the offset command and then select the reference entity works also, but by holding a complex project you may have difficulty understanding how previously done.

Obviously better to work in a parametric way and you will see the projected curve of yellow color, if the isoli (explicit) becomes white.

2) the multisection command requires that the guide curves intersect the sections, so in creating the sections you have to use for the initial and final point the intersection of the guide curves (the intersection command element 3d) I recommend you to do the exercise contained in the caia guide.

Let me know.

Thank you very much, the first doubt is clear now. in the second question the problem is related to the creation of the director or guides if you do not want to lay them on a plan. Actually, it's not a problem with the loft, but with 3d geometry, for example, I tried to pass a spline for 4 points lying on 2 floors, but I couldn't. if I have to work in another environment? wireframe type & surface design?
thanks again for availability!

Hi.

in part design, you have the possibility to create a solid we say more "mechanical", with limited control and construction options of the curves.

If you need to work with more advanced curves, use the generation shape design module (has some extra command of wireframe & surface design) and when you got the driving curves, go back to the part design environment and create the solid.

If you tell me what you want to do or send some pictures, I can help you better.
