Secret discovered by alicloud designer

Entering the world of electronics, PCB is indispensable. At the beginning, it was amazing. At that time, alicloud designer summer 08 was used, and now alicloud designer winnter 09 was used. I feel that it is not much different from alicloud designer 6.9, but the function is updated, it becomes more visual. Occasionally visit the forum or discover the unknown secrets. Put them here. Let's see the unknown.

(1) In the PCB layout stage: in the schematic diagram, you can select components in a region or click several components, and the quick cut key "T" + "S" can quickly switch to the PCB interface to select those components, press the "I" key and select the second item in the menu. Drag a box in the place you want, and the components will pop up in the box you drag.

(2) In the PCB layout stage: Does the component name appear around or even overlap each other in disorder? Select several components in the box, and then press the "A" shortcut key to display an encapsulation symbol image in the second option of the menu, click the image's top, bottom, left, right, top left, bottom left, top right, and bottom right. After confirmation, the component names are arranged neatly on the top, bottom, left, right, top left, bottom left, and right of the selected components ......

(3) Shift + S: Single-sided wiring, and other layers are invisible.

(4) Ctrl + Shift + scroll wheel: Switch different wiring Layers

(5) Ctrl + shft + T (top): Top alignment

(6) Ctrl + shft + B (bottom): Bottom alignment

(7) Ctrl + shft + L (left): Left alignment

(8) Ctrl + shft + T (right): Right alignment
(9) Ctrl + shft + H (horizonta): horizontal top offset

(10) Ctrl + shft + V (vertical): The offset in the vertical direction

(11) Ctrl + X: Flip left and right in the same plane of Sch or PCB

(12) Ctrl + Y: Flip up and down in the same plane of Sch or PCB

(13) S + L: select a local device or line for operation

(14) Click the menu schematic or PBC and select split vertical or split horizontal to view the design in two windows.

(15) N more devices should be flipped from the top layer to the bottom layer, or vice versa. Select all devices and press "L" and "OK" in the drag process.

(16) when multiple schematics appear in the same project, if the same net occurs, they must be connected together and cannot be connected as in the same Sch, to add Port external module interfaces, you can not add net.

(17) Port priority is higher than net. Net can only be in the same Sch, but port can make global (equivalent to local variable, global variable)

(18) after the completion of the Board, in the final modification Silk Screen Layer, You Can seitch to 3D, it will be better, and the opposite side can be directly flipped over to correct

(19) heat-generating devices similar to lm1085 can cover VCC with copper in a large area and add top solder to the pad to improve heat dissipation.

(20) Shift + M: magnifier

(21) If you only want to see a layer of Board and are not disturbed by others, you can select one by L.

(22) for digital boards, generally do not follow the bottom line. When copper is overwritten, the pattern prevents heat dissipation and better welding.

(23) design-board options-electronic grid: When the coordinates of the circle on which the cables are routed are lost, it is OK to select this one.

(24) You can draw a line when designing the schematic diagram and convert it with Shift + space.

(25) schematic fast cabling P-W

(26) PCB rapid cabling P-T

(27) when the sheet entry is modified again at the bottom layer when a vertical hierarchical schematic diagram is drawn, the sheet entry synchronized at the top layer cannot be modified in the same way as other copies, but can only be manually added to the sheet entry

(28) similar to PCB layout during Sch design, Shift + space is used to switch the cabling mode.

(29) Ctrl + shift in the PCB to highlight multiple cables

(30) P--V Miss hole

(31) copper-coated P--G

(32) P--T draw line

(33) for some reason (version or project), you can modify the design -- board options -- display physical/logical designators To Make It unmovable after drawing the wire.

(34) Tips for drawing n lines at the same time: shift to select multiple lines, then press TTM (multiple traces), OK

(35) If you do not want to lose net in paste, select edit-paste special-keep nets name.
